Conteúdo: | ABSTRACT: Feasible electrochemical CO2 reduction (ECR) requires accessible and efficient catalyst materials. Herein, we prepared ZnO-based catalysts decorated with various d-block metal oxides (Fe, Co, Ni, Cu). The ECR performance of the heterostructured catalyst materials was evaluated by using a flow-cell configuration. Our findings indicate that ZnO is an active catalyst substrate with tunable selectivity and stability, which depend on the formed heterostructures’ properties. We assessed and quantified the effect of the different d-block metals on the ECR activity of the composite catalyst. The CuZnO catalyst exhibited a stability of 30 h and a selectivity of 77% for CO at a current density of 100 mA cm−2 . This work aimed to provide a fundamental understanding of composite heterostructured materials’ properties and electrochemical behavior. We demonstrated that heterostructure engineering is a promising and cost-effective strategy for developing ECR catalysts with enhanced stability.
