Abstract
Up to date, the single-atom catalysts (SACs) have provided a sustainable solution for mitigating the energy crisis and improving environmental quality. The enhanced efficiency and selectivity in various chemical reactions relies on the rational design of metal atom coordination environments and a deep understanding of the underlying mechanisms. The atomic-level coordination between metal species and graphitic carbon nitride (g-C3N4) support offers potential unique characteristics and advantages. This review summarizes and provides insights into the recent progress of g-C3N4-based SACs. We discuss the principles and benefits of introducing atomic-level metal sites on g-C3N4, as well as essential preparation methods and characterization techniques. We also explore the applications of g-C3N4-based SACs in photocatalytic energy conversion and environmental remediation to gain a comprehensive understanding of how single-metal sites impact activity, selectivity, and stability. Finally, we highlight both the opportunities and challenges for development of g-C3N4-based SACs in the future.
期刊介绍:
Applied Catalysis B: Environment and Energy (formerly Applied Catalysis B: Environmental) is a journal that focuses on the transition towards cleaner and more sustainable energy sources. The journal's publications cover a wide range of topics, including:
1.Catalytic elimination of environmental pollutants such as nitrogen oxides, carbon monoxide, sulfur compounds, chlorinated and other organic compounds, and soot emitted from stationary or mobile sources.
2.Basic understanding of catalysts used in environmental pollution abatement, particularly in industrial processes.
3.All aspects of preparation, characterization, activation, deactivation, and regeneration of novel and commercially applicable environmental catalysts.
4.New catalytic routes and processes for the production of clean energy, such as hydrogen generation via catalytic fuel processing, and new catalysts and electrocatalysts for fuel cells.
5.Catalytic reactions that convert wastes into useful products.
6.Clean manufacturing techniques that replace toxic chemicals with environmentally friendly catalysts.
7.Scientific aspects of photocatalytic processes and a basic understanding of photocatalysts as applied to environmental problems.
8.New catalytic combustion technologies and catalysts.
9.New catalytic non-enzymatic transformations of biomass components.
The journal is abstracted and indexed in API Abstracts, Research Alert, Chemical Abstracts, Web of Science, Theoretical Chemical Engineering Abstracts, Engineering, Technology & Applied Sciences, and others.
