摘　　要：醇类的选择性催化氧化为相应的醛类和酮类是一类化学品生产的基本反应。然而,该反应需要苛刻的条件,如有毒的金属氧化物或高温高压,对环境有害,限制了该反应的进一步推广。光催化技术被认为是一种清洁和可持续的有机合成方法,共价三嗪框架是有前途的无金属材料,可应用于多种领域,特别是在光催化领域。介绍SBA-15负载含硫共价三嗪框架作为有机光活性聚合物,用于选择性地氧化醇类,由分子氧作为绿色氧化剂进行氧化。这些光催化剂在光催化反应过程中表现出高效率、高稳定性和良好的可重复使用性。Selective catalytic oxidation of alcohols to the corresponding aldehydes and ketones is a fundamental reaction in chemicals production.However,harsh conditions like toxic metal oxides or high temperature and pressure are required in this reaction,which are harmful to the environment and greatly restricted the further application.Photocatalytic technology nowadays is a clean and sustainable method for organic synthesis and covalent triazine frameworks are promising metal-free materials applied for versatile applications,especially in photocatalysis.Herein,we report the use of sulfur-containing covalent triazine frameworks coated on SBA-15 nanocomposites as organic photoactive polymers for the selective oxidation of alcohols,with molecular oxygen as a green oxidant.These photocatalysts exhibit high efficiency,high stability,and good reusability during the photocatalytic reaction.
