Over the past decade, graphitic carbon nitride(g-C_(3)N_(4)) has emerged as a universal photocatalyst toward various sustainable carbo-neutral technologies. Despite solar applications discrepancy, g-C_(3)N_(4) is still confronted with a general fatal issue of insufficient supply of thermodynamically active photocarriers due to its inferior solar harvesting ability and sluggish charge transfer dynamics. Fortunately, this could be significantly alleviated by the “all-in-one” defect engineering strategy, which enables a simultaneous amelioration of both textural uniqueness and intrinsic electronic band structures. To this end, we have summarized an unprecedently comprehensive discussion on defect controls including the vacancy/non-metallic dopant creation with optimized electronic band structure and electronic density, metallic doping with ultraactive coordinated environment(m–N_(x), m–C_(2)N_(2), m–O bonding), functional group grafting with optimized band structure, and promoted crystallinity with extended conjugation π system with weakened interlayered van der Waals interaction. Among them, the defect states induced by various defect types such as N vacancy, P/S/halogen dopants, and cyano group in boosting solar harvesting and accelerating photocarrier transfer have also been emphasized. more importantly, the shallow defect traps identified by femtosecond transient absorption spectra(fs-TAS) have also been highlighted. It is believed that this review would pave the way for future readers with a unique insight into a more precise defective g-C_(3)N_(4) “customization”, motivating more profound thinking and flourishing research outputs on g-C_(3)N_(4)-based photocatalysis.

Green Chemical Engineering 2024年第3期5卷 290-306页

作者： Litian Liu Yunlong Li Jialun He Qing Wang juan Deng Xiao Chen Chao Yu School of Environmental and Chemical Engineering Jiangsu University of Science and Technology

The burgeoning field of photocatalytic reduction of CO2has emerged as a remarkable promising solution to address some of the most pressing global energy and environmental issues which we face today. Researchers around the global have been striving to augment the efficiency of CO2photocatalytic reduction, employing strategies that range from modifying the fundamental properties of photocatalysts to suppress the electron-hole recombination, optimizing reaction conditions to achieve the highest yield, and conceptualizing and constructing photoreactors to improve the adsorption process. Among these factors, the photoreactor plays a critical role in enhancing the overall photocatalytic efficiency. Understanding the various types of photoreactors and their operational dynamic can significantly influence the experimental design, thus guiding the data collecting and analysis. Compared to the solid-liquid phase, gas-solid phase photocatalytic reduction of CO2is gaining recognition for its potential advantages, such as rapid molecular diffusion rates, adjustable CO2concentrations, and uniform and sufficient light exposure. Nonetheless, the currently reported gas-solid phase photoreactors are still in their infancy. In this review, we dissect the underlying mechanism of photocatalytic CO2reduction and the performance evaluation criteria of photoreactors, and review the development process of gas-solid phase photoreactors. Furthermore, we explore the evolution of gas-solid phase photoreactors, elucidating their growth trajectory and future possibilities. We present a comprehensive classification of gas-solid phase photoreactors,offering a new insight into their design and functionality, summarizing their strengths and inevitable ***, we provide a forward-looking perspective on the future developmental prospects of carbon neutrality.
