growth of the metal-organic framework material MFM-300(Fe) on an ultra-thin sheet of graphitic carbon nitride (g-CN) has been achieved exfoliation of bulk carbon nitride using supercritical CO. The resultant hybrid structure, CNNS/MFM-300(Fe), comprising carbon nitride nanosheets (CNNS) and MFM-300(Fe), shows excellent performance towards photocatalytic aerobic oxidation of benzylic C-H groups at room temperature under visible light. The catalytic activity is significantly improved compared to the parent g-CN, MFM-300(Fe) or physical mixtures of both. This facile strategy for preparing heterojunction photocatalysts demonstrates a green pathway for the efficient and economic oxidation of benzylic carbons to produce fine chemicals.
通过超临界CO2对块状氮化碳进行剥离，实现了金属有机骨架材料MFM-300(Fe)在超薄石墨相氮化碳(g-CN)片上的生长。所得的杂化结构CNNS/MFM-300(Fe)由氮化碳纳米片(CNNS)和MFM-300(Fe)组成，在室温可见光下对苄基C-H基团的光催化需氧氧化表现出优异的性能。与母体g-CN、MFM-300(Fe)或两者的物理混合物相比，催化活性显著提高。这种制备异质结光催化剂的简便策略为苄基碳高效经济地氧化生产精细化学品提供了一条绿色途径。
