Photoreforming of biomass to value-added chemicals and fuels is a chemical approach to extract photosynthetically-trapped energy in complex biomolecules which otherwise disintegrate naturally in the environment. Designing precise photocatalytic materials that can selectively break the sturdy, nature-designed biomass with multiplex chemical composition/bonding and inaccessible sites is central to deploying this technology. Polymeric carbon nitride (CN) comprised of a 2D network of condensed heptazine/triazine (C₆N₇/C₃N₃) core has shown great promise for photoreforming of biomass derivatives due to intriguing physicochemical and optical properties. This review comprehensively summarizes the state-of-the-art applications of CN-based photocatalysts for the conversion of lignocellulosic biomass derivatives. Various chemical and structural modifications in CN structure such as doping, surface functionalization, hybridization entailing to higher selectivity and conversion have been discussed aiming at providing valuable guidance for future CN-based materials design.

用于生物质衍生物光重整的聚合氮化碳基光催化剂

将生物质光转化为具有附加值的化学品和燃料是一种化学方法，可以提取复杂生物分子中光合作用捕获的能量，否则这些生物分子会在环境中自然分解。设计精确的光催化材料，可以选择性地破坏坚固的、自然设计的生物质，具有多重化学成分/结合和难以接近的位点，是部署这项技术的核心。聚合氮化碳 (CN) 由稠合庚嗪/三嗪 (C ₆ N ₇ /C ₃ N ₃) 核由于有趣的物理化学和光学特性，在生物质衍生物的光重整方面显示出巨大的希望。本综述全面总结了基于 CN 的光催化剂在木质纤维素生物质衍生物转化中的最新应用。已经讨论了 CN 结构中的各种化学和结构修饰，例如掺杂、表面功能化、需要更高选择性和转化率的杂化，旨在为未来的 CN 基材料设计提供有价值的指导。
