Abstract:
Copper/zinc oxide-based catalysts are important commercial catalysts for methanol production from
the thermochemical method in the gas phase, in this work, a copper/zinc oxide hexagonal plate (Cu/ZnO)
nanostructure was used as a photocatalytic catalyst for CO2 reduction in an aqueous medium. A 3% Cu/ZnO
catalyst was prepared by a two-step method, hydrothermal and chemical reduction in the polyol process. The
particle size, shape, and distribution of the catalysts were characterized by Scanning electron microscopy
(SEM). Photoluminescence and UV-diffuse reflectance spectroscopy were used to investigate optical
properties. The crystal structure of the synthesized catalysts was investigated using X-ray diffraction (XRD)
Photocatalytic reduction of CO2 using semiconductor catalysts is influenced by several parameters: catalyst
concentration, irradiation time, pH, and additives. The yields and selectivity of the CO2 photocatalytic
reduction can be influenced by the reaction media. The effects of basic additives on photocatalysis were
investigated, including sodium hydroxide and triethanolamine (TEA). Methanol yield can be increased by
controlling the pH of aqueous solution of the inorganic and organic additives. At the optimum reaction
condition, the yield of methanol was found to be 42 - 04 mmole/L/gcat under UV light. The catalytic reaction
mechanism of CO, reduction on Cu/ZnO in basic media was elucidated
