Visible light-driven photocatalytic reduction of CO2 into value-added chemical fuel is considered as an up-and-coming pathway for CO2 conversion utilizing green solar energy. Herein, we report heterostructures of NH2-MIL-101(Fe)/g-C3N4 (g-C3N4 = polymeric graphite-like carbon nitride) as prominent photocatalysts for the reduction of CO2 via a solvent-free reaction. Among these heterogeneous photocatalysts, NH2-MIL-101(Fe)/g-C3N4-30 wt % referred to as MCN-3 shows superior catalytic activity for photocatalytic reduction of CO2 to CO with a CO yield of 132.8 μmol g–1, which is more than 3.6 times higher than that for pristine NH2-MIL-101(Fe) and 6.9 times higher than that for sole g-C3N4. In virtue of the elaborate designed photocatalysts and the gas–solid interfacial route, the heterostructure of NH2-MIL-101(Fe)/g-C3N4 with efficient interfacial electron transfer between NH2-MIL-101(Fe) and g-C3N4 results in the boosted photocatalytic reduction of CO2 upon visible light irradiation.

可见光驱动的将CO 2光催化还原为增值化学燃料被认为是利用绿色太阳能转化CO 2的新兴途径。在本文中，我们报道了作为无溶剂反应还原CO 2的主要光催化剂，NH 2 -MIL-101（Fe）/ gC 3 N 4（gC 3 N 4 =聚合石墨状氮化碳）的异质结构。在这些非均相光催化剂中，称为MCN-3的NH 2 -MIL-101（Fe）/ gC 3 N 4 -30 wt％具有优异的催化活性，可用于光催化还原CO 2生成一氧化碳，其CO收率为132.8μmolg –1，比原始NH 2 -MIL-101（Fe）高3.6倍，比单一gC 3 N 4高6.9倍。在凭借精心设计的光催化剂和气体-固体界面路线，NH的异质结构2 -MIL-101（Fe）的/ GC 3 Ñ 4与NH之间有效界面的电子转移2 -MIL-101（Fe）和GC 3 N 4导致可见光辐照下增强的CO 2光催化还原。
