To date, HC is produced exclusively by charring organic precursors in inert atmospheres. One would not expect to find HC in rice hull ash (RHA), the byproduct of rice hull combustion processes. However, in developing approaches to depolymerize RHA SiO2 (90:10 wt% SiO2:C) to produce silica-depleted RHA or SDRHA40-60 (40–60 wt% SiO2) to tailor C:SiO2 ratios for carbothermal reduction reactions, the SDRHA carbon component is recently revisited. In more detailed efforts to characterize the form of carbon present in SDRHA, a series of analyses reveal graphitized carbon domains in amorphous matrices, i.e., HC, despite RHA being produced via combustion in an oxidizing atmosphere. Comprehensive electrochemical analyses on SDRHA40-60 find unexpected capacities far in excess (>700 mAh g−1) of reported values for HC and graphite. Electrochemical and STEM characterization suggest that the unexpected capacity may come from the nanoscale morphology of the amorphous carbon component. Given that RHA is a biowaste generated in kilotons/year worldwide, there seems to be an opportunity to develop sustainable high-capacity anode materials for alkali-ion storage systems.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 2","pages":""},"PeriodicalIF":6.5,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsu.202400667","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, metal organic framework(MOF) is used as self-sacrificing templates to prepare CoNiSe-P by hydrothermal with following selenylation and phosphorization treatment. Due to the hollow porous structure, rich electrochemical active sites and elements synergistic influence, the obtained CoNiSe-P electrode shows a high capacity of 838 C g−1, which is much higher than CoNiSe (322 C g−1) and CoNiP (616 C g−1). Furthermore, CoNiSe-P electrode shows excellent rate characteristic (685 C g−1 at 20 A g−1) and ultrahigh electrochemical stability with capacity retention of 99.6% after 10 000 cycles. More importantly, an asymmetric supercapacitor is assembled with CoNiSe-P as the positive electrode and nitrogen-doped porous carbon as the negative electrode delivers an energy density of 42.4 Wh kg−1 at 266.6 W kg−1 and maintains a specific capacitance of 96.8% after 10 000 cycles. Significantly, the asymmetric supercapacitor shows a high energy density up to 21.3 Wh kg−1 at a very high power density of 21.3 kW kg−1, higher than those of previously reported asymmetric supercapacitors.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 2","pages":""},"PeriodicalIF":6.5,"publicationDate":"2024-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143446902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Within robotics, silicone-based soft grippers are recently developed owing to their high adaptability and versatility allowing to deal with various objects. However, the soft grippers are difficult to recycle and may cause increased environmental impact. Here biodegradable soft pneumatic actuators reinforced by cellulose nanofibrils (CNF) distributed in a matrix of gelatin are presented. The results show that adding CNF enables 3D printability and provides tunable mechanical properties for the actuators. The actuator performance, with a bending angle of 80° and a blocked force of 0.1 N at 15 kPa, is comparable to state-of-the-art mold-casted pneumatic actuators from conventional silicone materials while being exclusively composed of non-toxic, biodegradable materials and fabricated by additive manufacturing techniques. Moreover, the actuators exhibit self-healing ability and enable object manipulation when formed in a gripper configuration. The mold-free approach and achieved functionalities establish new opportunities for soft-robotics, across various fields including healthcare, packaging, or even environmental monitoring. The performance of the gripper shows that CNF can be used in the creation of eco-friendly high-performance soft robots and contribute to the advancement of sustainable and green robotics.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 2","pages":""},"PeriodicalIF":6.5,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsu.202400450","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143446831","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a series of rare-earth (RE) elements doped RuO2 nanorods is developed as high-performance OER electrocatalysts. X-ray absorption spectroscopy suggests that RE doping regulates the local coordination environment around Ru sites, lowers the valance of Ru, and shortens the Ru─O─Ru(M) bond length, which enhances structural stability. Among the RE-RuO2 samples, Sm-RuO2 exhibits remarkable performance with a low overpotential of 283 mV to reach 100 mA cm−2 and maintained stability for over 140 h at 10 mA cm−2. Moreover, the PEM electrolyzer using Sm-RuO2 as the anode can be stably operated at 500 mA cm−2 for 15 h. Electrochemical analysis, X-ray photoelectron spectroscopy, and in situ Raman spectroscopy show that Sm doping lowers the d-band center, reduces the adsorption energy of O intermediates to enhance the OER activity, and restrains excessive oxidation of Ru sites while stabilizing lattice oxygen during the OER process, thereby enhancing OER stability. This work offers valuable insights into improving the stability of metal oxide catalysts in acidic electrolytes.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 2","pages":""},"PeriodicalIF":6.5,"publicationDate":"2024-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143446834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, an efficient photocatalytic system is reported that can produce high-valued tartaric acid or formaldehyde and simultaneous producing hydrogen. At optimized conditions, the directional conversion of glycolic acid into tartaric acid is achieved with a selectivity of 76.24%, and the selectivity of methanol oxidation into formaldehyde reaches 88.21%. A high hydrogen production rate of 21.43 mmol·g−1·h−1 is obtained using glycolic acid as substrate. Mechanism studies reveal that α-C─H bond is preferentially activated in glycolic acid adsorbed on the photocatalyst, while O─H bond is preferentially activated in methanol, forming carbon-centered radical (•CH(OH)COOH) or oxygen-centered radical (CH3O•) for subsequent coupling or oxidation reactions. This work demonstrates the selective control of the photocatalytic conversion process of different hydroxyl compounds, providing a new perspective for achieving organic compounds selective activation coupled with hydrogen production.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 2","pages":""},"PeriodicalIF":6.5,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143446687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is previously revealed that Brønsted acid-free Sn-Beta zeolites selectively produced light olefins from polyolefin cracking. Brønsted acid sites ionize olefins by protonation and the generated carbenium ions are converted into other hydrocarbons via various reactions, thereby the elimination of their effects led to the improvement of light olefin production ability. However, the deactivation of zeolites by coke deposition is a critical problem for industrialization. Inhibition of coking deactivation is previously achieved by doping Cr6+ species connected to silanol groups in zeolites. This work aimed to inhibit coke deposition and realize selective and continuous production of light olefins through repetitive polyolefin catalytic cracking. Sn-Beta zeolites are prepared with various crystallinity by changing the feed fluoride ions content in their synthesis and found that their activity on low-density polyethylene (LDPE) cracking strongly depended on the feed F/Si ratios, implying the active sites for polyolefin cracking are Lewis acidic open-Sn sites. Moreover, Cr6+-doped Sn-Beta zeolites showed over 45% light olefin yields even in the third LDPE cracking test, although excess Cr adding led to reduce the catalytic activity of Sn-Beta zeolites.","PeriodicalId":7294,"journal":{"name":"Advanced Sustainable Systems","volume":"9 3","pages":""},"PeriodicalIF":6.5,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/adsu.202400625","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143688665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
