Abstract: Disclosed in the present invention is an application of a metal sulfide piezoelectric material in piezoelectric catalytic reduction of CO2. The internal electric field generated by the piezoelectric material under external mechanical stimulation pushes electrons and holes to migrate in opposite directions, so that natural advantages are provided for separation and transmission of electron-hole pairs, but there is no report in the prior art that CO2 is reduced into C2+ products by means of piezoelectric catalysis. The present invention provides a metal sulfide piezoelectric nanomaterial and a preparation method therefor. The metal sulfide piezoelectric nanomaterial is used for piezoelectric catalytic reduction of CO2 for the first time, especially piezoelectric catalytic reduction of CO2 to obtain C2+ products so as to broaden the technical route of catalytic reduction of CO2.

Abstract: Monodisperse polystyrene microspheres are self-assembled on a conductive surface of FTO glass by vertical deposition method to prepare three-dimensional ordered photonic crystal opal template; the three-dimensional ordered photonic crystal opal template is immersed in a solution containing rhodium source, titanium source and strontium source, and is then calcined to prepare a rhodium doped strontium titanate inverse opal material; and the rhodium doped strontium titanate inverse opal material is added to water containing pollutants, and is then subjected to illumination and/or ultrasonic treatment to complete the removal of the pollutants in the water. The three-dimensional ordered macroporous rhodium doped strontium titanate inverse opal material may be applied in the field of photocatalysis. Under the action of external force, a built-in electric field formed by the spontaneous polarization of the material may effectively separate the photo-induced carriers, which may thus enhance the photocatalytic performance and improve the photocatalytic efficiency.
