Description

technical field

[0001] The invention belongs to the technical field of new energy materials and electrochemical catalysis, and in particular relates to a silver selenide nano-catalyst and its preparation method and application. Background technique

[0002] Global warming and energy crisis are two major challenges facing human society. Atmospheric CO 2 Concentrations of carbon dioxide continue to rise, triggering the "greenhouse effect", which greatly endangers the environment on which we live. reduce CO 2 Emissions, efficient use of CO 2 , building an environment-friendly, energy-saving low-carbon economy has become a hot spot of extensive research at home and abroad. CO 2 as a C 1 resources, if it can be reduced to synthesize various chemicals and fuels (hydrocarbons, alcohols, etc.), both CO 2 The effective reduction of emissions can also be obtained as a reusable resource, which further promotes the deep integration of technological innovation and economic and soc...
