Abstract

It is established that crystalline graphite-like carbon nitride (CGCN) exhibits high photocatalytic activity in the process of chemoselective reduction of furfural to furfuryl alcohol in the presence of co-catalysts under the action of visible light by electron-donating substrates, such as methanol/water and ethanol/water, in an acidic medium. When palladium chloride additives are introduced into the reaction mixture, the rate of the process is higher than with the participation of the Pd/SiO2 co-catalyst. This phenomenon may be due to the in situ formation of the CGCN/Pd0 composite photocatalyst in the presence of PdCl2, where the photogenerated charges are better separated than in the CGCN-Pd/SiO2 system. The effective quantum yield of furfural reduction is 56% at λirr = 405 nm) under optimal conditions.

纳米晶氮化碳和钯共催化剂在可见光影响下将糠醛化学选择性光催化还原为糠醇
研究证实,在酸性介质中,甲醇/水和乙醇/水等电子捐赠底物在可见光作用下,在助催化剂存在下,结晶石墨状氮化碳(CGCN)在糠醛化学选择性还原为糠醇的过程中表现出很高的光催化活性。当在反应混合物中加入氯化钯添加剂时,该过程的速率要高于有 Pd/SiO2 助催化剂参与时的速率。这种现象可能是由于在氯化钯存在下原位形成了 CGCN/Pd0 复合光催化剂,与 CGCN-Pd/SiO2 体系相比,光生电荷得到了更好的分离。在最佳条件下(λirr = 405 nm),糠醛还原的有效量子产率为 56%。
