Abstract

Along with industrial development, various organic pollutants are accumulating within the global ecosystems, and their emissions are continuously increasing. Accordingly, research and technological development are actively progressing to decompose/convert organic pollutants using sustainable and energy-efficient methods. Carbon nitride-based photocatalysts are receiving attention for their excellent organic pollutant removal efficiency under mild conditions, solar energy utilization, high chemical stability in various conditions, and reactive oxygen species generation capabilities. However, their photocatalytic performance can vary considerably depending on the type of reaction system (aqueous, gas-phase, or solid-phase), because mass transfer, catalyst–pollutant interactions, and reaction pathways differ according to the reaction environment and the physicochemical properties of the pollutants. This review summarizes the key factors that influence the photocatalytic decomposition of organic pollutants present in various phases and the recent research trends of carbon nitride-based photocatalysts for performance improvement along with their modification strategies.

氮化碳光催化剂多相降解有机污染物的研究进展

随着工业的发展，各种有机污染物在全球生态系统中不断积累，其排放量也在不断增加。因此，利用可持续和节能的方法分解/转化有机污染物的研究和技术开发正在积极进行。氮化碳基光催化剂因其在温和条件下优异的有机污染物去除效率、太阳能利用、各种条件下的高化学稳定性以及活性氧生成能力而受到人们的关注。然而，它们的光催化性能会根据反应体系的类型（水相、气相或固相）而有很大差异，因为传质、催化剂-污染物相互作用和反应途径会根据反应环境和污染物的物理化学性质而有所不同。本文综述了影响氮化碳光催化分解各相有机污染物的关键因素，以及氮化碳基光催化剂性能改进的最新研究趋势和改性策略。

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.
