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":"2 3","pages":""},"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":"2 3","pages":""},"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}

However, the current sensors face limitations regarding low sensitivity, poor stability, and inadequate adhesion bonding between stimuli-responsive functional materials and flexible substrates. To overcome these challenges and enable the further development of sensor devices, surface modification of stimuli-responsive materials with amyloid aggregates has emerged as a promising approach to enhance functionality and create superior multifunctional sensors. This review presents recent research advancements in the flexible sensors based on protein amyloid aggregation. The article begins by explaining the basic principles of protein amyloid aggregation, followed by outlining the process of preparing 1D to 3D amyloid-based composite materials. Finally, it discusses the utilization of protein amyloid aggregation as a surface modification technique for developing flexible sensors. Based on this foundation, we identify the shortcomings associated with protein amyloid aggregate composites and propose possible solutions to address them. We believe that comprehensive investigations in this area will expedite the development of high-performance flexible sensors with high sensitivity, high structural stability, and strong interface adhesion, especially the implantable flexible sensors for health monitoring.","PeriodicalId":100403,"journal":{"name":"Electron","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/elt2.59","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141812129","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.
