Scheme 1. The main reaction and side reactions in the epoxidation of allyl alcohol catalyzed over TS-1 catalyst. On the other hand, the diffusion property of the TS-1 can be improved by decreasing the ...

为解决CO2光催化还原选择性差与H2O2绿色合成难题，研究人员通过浸渍法（IMP）在CaTiO3（CTO）表面构建双功能Ag助催化剂体系，实现CO产率较光沉积法（PD）提升2倍并同步生成H2O2，为碳资源转化提供新策略。 全球气候危机与能源转型背景下，如何将温室气体CO 2 ...

为解决传统蒽醌法合成H2O2的高能耗与污染问题，研究人员通过调控π电子密度设计新型共轭聚合物催化剂A-AB，实现*OH中间体稳定化，使H2O直接氧化生成H2O2的速率达8700 μmol g-1 h-1，为双路径光催化体系提供理论依据。 当前，过氧化氢（H 2 O 2 ）作为绿色氧化剂在 ...
