Abstract

The development of hydrogen energy is crucial for achieving global dual-carbon strategic goals, namely "carbon peak" and "carbon neutrality." Photocatalytic water splitting, powered by solar energy, presents a promising approach to hydrogen production. Advancing this technology requires the development of photocatalysts that are cost-effective, highly active, and stable. As a non-metallic semiconductor, g-C₃N₄ stands out for its potential in sustainable energy and environmental remediation technologies, garnering considerable interest for its efficiency in harnessing light-driven reactions. Although g-C₃N₄ exhibits promising characteristics, its practical application is significantly hindered by the rapid recombination of photogenerated charge carriers and its limited light absorption range. This review highlights various strategies employed to improve the photocatalytic hydrogen production efficiency of g-C₃N₄, including heteroatom doping, microstructure control, co-catalyst modification, defect engineering, and heterojunction construction. These strategies enhance active site density, light absorption capacity, and photogenerated charge separation in g-C₃N₄, thereby boosting electron migration rates and improving photocatalytic hydrogen production. Additionally, we explore the potential of integrating cutting-edge AI technology with advanced instrumentation for the prediction, design, preparation, and in-situ characterization of g-C₃N₄-based photocatalytic systems. This review aims to offer key insights into the design, development, and practical application of innovative, high-performance carbon-based catalysts.

期刊介绍： Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
