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
介孔氮化碳 (mpg-C(3)N(4)) 聚合物可作为无金属光催化剂激活 O(2) 以在可见光下选择性氧化苯甲醇,避免成本、毒性和纯化问题与相应的过渡金属系统相关联。通过结合 mpg-C(3)N(4) 的表面碱度和半导体功能,光催化系统可以实现高催化选择性以生成苯甲醛。无金属光催化系统还选择性地将其他醇底物转化为其相应的醛/酮,展示了使用硝酰基自由基进入传统温和自由基化学的潜在途径。
