Mesoporous carbon nitride (mpg-C(3)N(4)) polymer can function as a metal-free photocatalyst to activate O(2) for the selective oxidation of benzyl alcohols with visible light, avoiding the cost, toxicity, and purification problems associated with corresponding transition-metal systems. By combining the surface basicity and semiconductor functions of mpg-C(3)N(4), the photocatalytic system can realize a high catalytic selectivity to generate benzaldehyde. The metal-free photocatalytic system also selectively converts other alcohol substrates to their corresponding aldehydes/ketones, demonstrating a potential pathway of accessing traditional mild radical chemistry with nitroxyl radicals.
介孔氮化碳（mpg-C(3)N(4)）聚合物可用作无金属光催化剂，在可见光下激活 O(2)，用于选择性氧化苄醇，避免了相应过渡金属体系的成本、毒性和纯化问题。通过结合 mpg-C(3)N(4)的表面碱性和半导体功能，该光催化体系可以实现高催化选择性，生成苯甲醛。无金属光催化体系还选择性地将其他醇底物转化为相应的醛/酮，展示了通过氮氧自由基实现传统温和自由基化学的潜在途径。
