摘　　要：通过光催化CO_(2)还原实现CO_(2)减排和高值利用是目前科学研究的热点问题。设计合成了2D/3D NiAl-LDH/ZnIn_(2)S_(4)复合材料,电化学阻抗谱和瞬态光电流测试结果表明,NiAl-LDH和ZnIn_(2)S_(4)二者之间紧密的界面接触和异质结的构筑显著促进光生电子的界面转移,从而增强光催化CO_(2)还原效率。2D/3D NiAl-LDH/ZnIn_(2)S_(4)复合材料的CO产量分别是单相ZnIn_(2)S_(4)和NiAl-LDH的23.8倍和1.7倍。The CO_(2)mitigation and value-added utilization via photocatalytic CO_(2)reduction has been one of the hottest issues of scientific research.Designed and synthesized a 2D/3D NiAl-LDH/ZnIn_(2)S_(4)composite.The testing results of electrochemical impedance spectroscopy and transient photocurrent response verified that the intimate interfacial contact between NiAl-LDH and ZnIn_(2)S_(4)and formation of heterojunctions contributed to the efficient interfacial electron transfer,thereafter enhancing photocatalytic CO_(2)reduction.The CO yield over 2D/3D NiAl-LDH/ZnIn_(2)S_(4)composites was 23.8 times and 1.7 times higher than that over individual ZnIn_(2)S_(4)and NiAl-LDH,respectively.
