While the relatively inert nature of C<img>H and C<img>O bond (e.g., methane and carbon dioxide) and uncontrollable coupling of C<img>C bond render the selective activation and controllable transformation of C1 molecules to high-value-added products challenging in C1 chemistry. Catalytic conversion of C1 energy molecules under mild conditions enables a better control of the selectivity of the desired products, however, which requires highly active catalysts to lower the reaction energy barriers. Besides designing efficient catalysts to promote C1 molecules conversion, employing electro-catalysis and photo-catalysis to circumvent the thermodynamic limitations is regarded as promising ways for C1 catalysis at low temperatures. Benefiting from the advanced technology for catalyst synthesis, reactor design, mechanism understanding, catalytic conversion of C1 molecules under mild conditions has made significant progress from 2010 to 2020. In this review, we summarized the typical catalytic processes and representative catalysts for transforming methane, carbon monoxide, methanol and carbon dioxide into high value-added chemicals with a reaction temperatures below 200 °C driven by thermo-catalysis, electro-catalysis, and photo-catalysis. Besides, a short perspective is offered to highlight possible future research directions towards C1 molecules conversion under mild conditions. It is expected to provide a useful reference for the readers to design better catalysts and reaction process for mild conversion of C1 molecules efficiently in future.</p></div>","PeriodicalId":307,"journal":{"name":"EnergyChem","volume":"3 1","pages":"Article 100050"},"PeriodicalIF":25.1,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.enchem.2020.100050","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"3246454","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}

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.

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.

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.
