Title:
PREPARATION METHOD FOR CD0.5ZN0.5S AND EXPERIMENTAL METHOD FOR NITROGEN FIXATION UNDER PHOTOCATALYSIS THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/246306
Kind Code:
A1
Abstract:
Disclosed in the present invention are a preparation method for Cd0.5Zn0.5S and an experimental method for nitrogen fixation under photocatalysis thereof. Under irradiation of visible light, photogenerated electrons are excited to a conduction band, leaving vacancies in a valence band, and then photogenerated electrons and holes migrate to the surface of a catalyst and participate in a redox reaction. Methanol provides hydrogen protons for the reaction, and nitrogen is reduced into ammonia. The present invention relates to the technical field of chemical catalysts. According to the preparation method for Cd0.5Zn0.5S and the experimental method for nitrogen fixation under photocatalysis thereof, when the synthesis temperature is 200ºC, compared with samples at another temperature, the photocatalyst Cd0.5Zn0.5S has a significantly strong signal at g=2.003. Therefore, in a photocatalytic nitrogen fixation reaction system, using Cd0.5Zn0.5S as a catalyst and using methanol as a proton source can effectively reduce nitrogen in the atmosphere into ammonia, which is effective for mankind. Methanol not only serves as a proton source, but can also react with photogenerated holes, such that the reaction can be operated more effectively.
