Traditional disposal methods such as landfilling and incineration not only exacerbate environmental degradation by releasing harmful chemicals and greenhouse gases, but also squander finite resources that could otherwise be recycled or repurposed. Upcycling is a kind of plastic recycling technology that converts plastic waste into high-value chemicals and helps to avoid resource waste and environmental pollution. Electrocatalytic upcycling emerges as a novel technology distinguished by its mild operational conditions, high transformation efficiency and product selectivity. This review commences with an overview of the recycling and upcycling technology employed in plastic waste management and the respective advantages and inherent limitations are also delineated. The different types of plastic waste upcycled by electrocatalytic strategy are then discussed and the plastic waste transformation process is examined together with the mechanisms underlying the electrocatalytic upcycling. Furthermore, the structure-activity relationships between electrocatalysts and plastic waste upcycling performance are also elucidated. The review aims to furnish readers with a comprehensive understanding of the electrocatalytic techniques for plastic waste upcycling and to provide a guidance for the design of electrocatalysts towards efficient plastic waste transformation.","PeriodicalId":100403,"journal":{"name":"Electron","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.63","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142099971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The catalytic performance of cobalt phosphides largely depends on the phase structure, but figuring out the optimal phase towards HER remains challenging due to their diverse stoichiometries. In our work, a series of cobalt phosphide nanoparticles with different phase structures but similar particle sizes (CoP-Co2P, Co2P-Co, Co2P, and CoP) on a porous carbon network (PC) were accurately synthesized. The CoP-Co2P/PC heterostructure demonstrates upgraded HER catalytic activity with a low overpotential of 96.7 and 162.1 mV at 10 mA cm−2 in 1 M KOH and 1 M phosphate-buffered saline solution, respectively, with a long-term (120 h) durability. In addition, the CoP-Co2P/PC exhibits good HER performance in alkaline seawater, with a small overpotential of 111.2 mV at 10 mA cm−2 and a low Tafel slope of 64.2 mV dec−1, as well as promising stability. Density functional theory results show that the Co2P side of the CoP-Co2P/PC heterostructure has the best Gibbs free energy of each step for HER, which contributes to the high HER activity. This study sets the stage for the advancement of high-performance HER electrocatalysts and the implementation of large-scale seawater electrolysis.","PeriodicalId":100403,"journal":{"name":"Electron","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.58","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141805956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The next-generation electrochemical energy storage (EES), incorporating flow battery (FB) and metal-based battery (MB, Li, Na, Zn, Mg, etc.) received more attention. The flammable electrolytes in nonaqueous batteries have raised serious safety hazards and more unconventional electrolyte systems have been proposed recently. An emerging class of electrolytes, eutectic electrolytes have been reported in many batteries due to the facile preparation, concentrated states, and unique ion transport properties. In FB, eutectic electrolytes can significantly increase the energy density by promoting the molar ratio of redox active materials. In MB, eutectic electrolytes reduce the vapor pressure and toxicity, inhibit metal dendrites growth, and enlarge the electrochemical window. In this review, we summarize the progress status of different eutectic electrolytes on both FBs and MBs.

Herein, we proposed an extensible strategy to synthesize MOF‐derived Co/C‐anchored MoS2‐based PCMs using high‐temperature carbonation of flower‐like MoS2 grown in situ by ZIF67 and vacuum impregnation of paraffin. The resulting MoS2@Co/C‐paraffin composite PCMs exhibited good thermal storage density, thermal cycling stability, and long‐term durability. The thermal conductivity of composite PCMs was 44% higher than that of pristine paraffin due to the construction of low interfacial thermal resistance. More attractively, our designed composite PCMs also possessed −57.15 dB minimum reflection loss at 9.2 GHz with a thickness of 3.0 mm, corresponding to an effective absorption bandwidth of 3.86 GHz. The excellent microwave absorption was attributed to the multicomponent synergy of magnetic loss from Co nanoparticles and conductive loss from MOF‐derived carbon layers, and multiple reflection of MoS2 nanowrinkle, along with good impedance matching. This study provided a meaningful reference for the widespread application of composite PCMs combining thermal storage, thermal conduction, and microwave absorption in high‐power miniaturized electronic devices.","PeriodicalId":100403,"journal":{"name":"Electron","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, most studies are conducted under mild laboratory conditions, but for some extreme environments, such as Mars and space stations, there is an urgent need to develop new catalysts satisfying such special requirements. Conventional catalytic materials mainly focus on metals and narrow bandgap semiconductor materials, while the research on wide and ultrawide bandgap materials that can inherently withstand extreme conditions has not received enough attention. Given the robust stability and excellent physico-chemical properties of diamond, it can be expected to perform in harsh environments for electrocatalysis or photocatalysis that has not been investigated thoroughly. Here, this review summarizes the catalytic functionality of diamond-based electrodes with various but tunable product selectivity to obtain the varied C1 or C2+ products, and discusses some important factors playing a key role in manipulating the catalytic activity. Moreover, the unique solvation electron effect of diamond gives it a significant advantage in photocatalytic conversions which is also summarized in this mini-review. In the end, prospects are made for the application of diamond-based catalysts under various extreme conditions. The challenges that may be faced in practical applications are also summarized and future breakthrough directions are proposed at the end.","PeriodicalId":100403,"journal":{"name":"Electron","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.45","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141691825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
