Zinc-Based Materials for Photoelectrochemical Reduction of Carbon Dioxide

Abstract

As one of the most effective ways to convert carbon dioxide (CO 2 ) into fuels and/or high-value-added chemicals, photoelectrochemical (PEC) reduction of CO 2 will potentially alleviate both the environment and energy crises. Zinc-based materials are ideal PEC catalysts due to their variable energy band structures, wide sources, and environmental friendliness. However, the achievements and developmental trends of zinc-based PEC catalysts for CO 2 reduction have not been systematically summarized. In this review, the principles of PEC CO 2 reduction are briefly introduced. Various zinc-based PEC catalysts, including ZnO, Cu 2 ZnSnS 4 , Cu 2 ZnGeS 4 , ZnSe, ZnTe, Zn alloys, and a zinc porphyrin complex, for the reduction of CO 2 are summarized. The challenges and future developing trends of these zinc-based PEC catalysts are prospected.

To this end, kinetic modeling and reactor design of methanol formation have been studied by many researchers in the last decade.…”

Tuning the Carrier Transfer Behavior of Coaxial ZnO/ZnS/ZnIn2S4Nanorods with a Coherent Lattice Heterojunction Structure for Photoelectrochemical Water Oxidation

“…Among the recent interesting materials, zinc oxide (ZnO) deserves particular attention due to its high electron mobility, transparent conductivity, and suitable bandgap with sufficient redox potential for water splitting. However, its large bandgap, severe degradation, and rapid charge recombination limit its photocatalytic performance [4] …”
