In order to improve the solar-to-chemical conversion efficiency of pristine semiconductors, combining them with cocatalysts to form heterostructures has been extensively investigated. Among studied formulations, bimetallic nanoparticles (NPs), featuring enhanced light harvesting, efficient capture of photogenerated electrons and abundant surface active sites are ideal cocatalysts to improve the photocatalytic performance of semiconductor-based photocatalysts. In this review, we begin with a concise overview of representative synthesis and characterization methods of bimetallic NPs. Then, we predominantly summarize the typical applications of semiconductor/bimetallic NPs-based composites in photoredox catalysis, including hydrogen evolution, carbon dioxide reduction, selective organic synthesis and environmental remediation. In particular, we highlight the regulatory effects of parameters of bimetallic NPs (composition, structure, morphology, size, atomic arrangement, loading position, etc.) on the photocatalytic activity and selectivity. Finally, the remaining challenges and future perspectives for the utilization of bimetallic NPs in photoredox catalysis are discussed and anticipated to stimulate the sparkling ideas in the construction of high-efficiency semiconductor/bimetallic NPs-based photocatalytic systems.</p></div>","PeriodicalId":307,"journal":{"name":"EnergyChem","volume":"3 1","pages":"Article 100047"},"PeriodicalIF":25.1,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.enchem.2020.100047","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"2639046","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}

Since it was proposed in the 1970s and commercialized in 1991, LIBs have been pursuing higher energy, higher power, higher safety and higher durability. Therefore, there is an urgent need to develop more efficient anode materials to overcome the capacity and rate bottlenecks of commercial graphite. Oxide anodes stand out in terms of high capacity and working potential, <em>e.g.</em>, Li<sub>4</sub>Ti<sub>5</sub>O<sub>12</sub> has been a high-performance safe anode material. Yet developed early, most of oxide anodes suffer from low conductivity, low initial coulombic efficiency and large volume change during lithium/delithiation process. Recently, defect engineering has significantly improved the performance of oxide anodes and alleviated the above problems. In this review, we present the fundamentals, challenges and recent research progress on defective oxide anodes of LIBs. Firstly, the development history of LIBs and oxide anode is briefly introduced.

Although much progress has been achieved, the development of better CDI technologies, especially through the design and synthesis of various porous carbonaceous materials with enhanced CDI performance, continues to attract increasing interest within the scientific fraternity. Considering that previous traditional porous carbons might suffer from deficient salt adsorption capacity, the nitrogenization of porous carbons, which brings new opportunities for CDI applications, has emerged as an effective strategy to modify the surface characteristics of porous carbons and ultimately improve their CDI performance. This review summarizes the recent significant breakthroughs on the construction of NCs, including <em>in situ</em> doping and post-treatment strategies, and their practices in the field of CDI to impart a comprehensive understanding of the strategic evolution of the synthetic approaches to nitrogen-doped carbons (NCs) with remarkable CDI characteristics. We present an exhaustive analysis of newly synthesized NCs and the impact of their compositional and structural features on their CDI performance; further, we highlight a special emphasis on the possible role of nitrogen dopants in the CDI process.
