Cathode compensation agent is a favorable strategy to make up for the loss of active sodium ions consumed by HC anode. Yet it lacks agent that effectively decomposes to increase the active sodium ions as well as regulate carbon defects for decreasing the irreversible sodium ions consumption. Here, we propose 1,2-dihydroxybenzene Na salt (NaDB) as a cathode compensation agent with high specific capacity (347.9 mAh g), lower desodiation potential (2.4–2.8 V) and high utilization (99%). Meanwhile, its byproduct could functionalize HC with more CO groups and promotes its reversible capacity. Consequently, the presodiation hard carbon (pHC) anode exhibits highly reversible capacity of 204.7 mAh g with 98% retention at 5 C rate over 1000 cycles. Moreover, with 5 wt% NaDB initially coated on the NaV(PO) (NVP) cathode, the capacity retention of NVP + NaDB|HC cell could increase form 36%–89% after 1000 cycles at 1 C rate. This work provides a new avenue to improve SIBs reversible capacity and cycling performance through designing functional cathode compensation agent.","PeriodicalId":12744,"journal":{"name":"Green Energy & Environment","volume":"12 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140036479","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The introduction of defects emerges as a promising strategy, effectively modifying the electronic structure of active sites. This optimization influences the adsorption energy of intermediates, thereby mitigating reaction energy barriers, altering paths, enhancing selectivity, and ultimately improving the catalytic efficiency of electrocatalysts. To elucidate the impact of defects on the electrocatalytic process, we comprehensively outline the roles of various point defects, their synthetic methodologies, and characterization techniques. Importantly, we consolidate insights into the relationship between point defects and catalytic activity for hydrogen/oxygen evolution and CO/O/N reduction reactions by integrating mechanisms from diverse reactions. This underscores the pivotal role of point defects in enhancing catalytic performance. At last, the principal challenges and prospects associated with point defects in current electrocatalysts are proposed, emphasizing their role in advancing the efficiency of electrochemical energy storage and conversion materials.","PeriodicalId":12744,"journal":{"name":"Green Energy & Environment","volume":"6 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139987778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, efficient seawater splitting is hindered by slow kinetics caused by the ultra-low conductivity and the presence of bacteria, microorganisms, and stray ions in seawater. Additionally, producing hydrogen on an industrial scale is challenging due to the high production cost. To address these challenges, this review presents that from the catalyst point of view, designing catalysts with high catalytic activity and high stability can directly affect the rate and effect of seawater splitting. From the ion transfer perspective, designing membranes can block harmful ions, improving the stability of seawater splitting. From the energy point of view, mixed seawater systems and self-powered systems also provide new and low-energy research systems for seawater splitting. Finally, ideas and directions for further research on direct seawater splitting in the future are pointed out, with the aims of achieving low-cost and high-efficiency hydrogen production.","PeriodicalId":12744,"journal":{"name":"Green Energy & Environment","volume":"22 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139679409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The as-prepared CoTCPP/BiOBr-2 shows optimized photocatalytic performance for CO2 conversion into CO and CH4 upon irradiation with 300 W Xe lamp, which is 2.03 and 2.58 times compared to that of BiOBr, respectively. The introduced CoTCPP significantly enhanced light absorption properties, promoted rapid separation of photogenerated carriers and boosted the chemisorption of CO2 molecules. The metal Co2+ at the center of the porphyrin molecules also acts as adsorption center for CO2 molecules, boosting the CO2 convert into CO and CH4. The possible mechanism of CO2 photoreduction was explored by in-situ FT-IR spectra.

In this review, we investigate the development of industrial-waste-based functional materials for various gas pollutant removal and consider the relevant reaction mechanism according to different types of industrial solid waste. We see a recent effort towards achieving high-performance environmental functional materials via chemical or physical modification, in which the active components, pore size, and phase structure can be altered. The review will discuss the potential of using industrial solid wastes, these modified materials, or synthesized materials from raw waste precursors for the removal of air pollutants, including SO2, NOx, Hg0, H2S, VOCs, and CO2. The challenges still need to be addressed to realize this potential and the prospects for future research fully. The suggests for future directions include determining the optimal composition of these materials, calculating the real reaction rate and turnover frequency, developing effective treatment methods, and establishing chemical component databases of raw industrial solid waste for catalysts/adsorbent preparation.","PeriodicalId":12744,"journal":{"name":"Green Energy & Environment","volume":"13 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139583265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
