Abstract

Abstract:

Constructing nanoscale heterostructures is an important strategy to improve the photocatalytic reduction of carbon dioxide.Phosphomolybdic acid and copper oxide（CuO-PMA） co-assembled nanosheets were prepared by solvothermal method，and structural characterization and performance evaluation were conducted.Firstly，the morphology，composition，structure and element valence，etc.of the newly prepared composite materials were characterized by TEM，EDS，infrared spectroscopy，XPS and XRD.Then，their photocatalytic CO₂ reduction performance was evaluated.Finally，the photocatalytic CO₂reduction mechanism of CuO-PMA was studied.The prepared nanosheets were shuttle shaped with a length of about 1 μm and a width of around 100 nm.The elemental characterization of the structure confirmed that the obtained nanosheets were composed of CuO and PMA.In addition，compared with CuO and PMA，CuO-PMA nanosheets had a larger specific surface area（52.03 m²/g）.The rates of photocatalytic reduction of CO₂ to CH₄ and CO by CuO PMA under visible light irradiation were 210.12 μmol/（g·h） and 486.70 μmol/（g·h），respectively，which were 8.4，10.2 times and 2.5，2.3 times higher than those of pure CuO and PMA，respectively.The carrier separation and transport performance in CuO-PMA heterostructures was improved，thereby promoting the generation of electrochemical CO₂ conversion reactions and deriving the corresponding photocatalytic CO₂ reduction mechanism.
