Abstract

The invention belongs to the technical field of fuel cells, and discloses a novel sacrificial fuel cell, a production method thereof, and an application thereof in carbon dioxide reuse through a paired synthesis method. The novel sacrificial fuel cell is obtained through constructing a sodium sulfide-oxygen fuel cell with TiO2 modified indium tin oxide as an anode and Pt-Cu2O as a cathode and catalytically reducing carbon dioxide on the cathode, and the self electric energy of the novel sacrificial fuel cell is consumed to achieve the carbon dioxide reduction purpose. The application of the novel sacrificial fuel cell in the carbon dioxide reuse through the paired synthesis method has the characteristics of simplicity in operation, environmental protection, safety, and consumption of the self electric energy of the fuel cell, and converts the carbon dioxide into an organic fuel.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a novel sacrificial fuel cell and a preparation method thereof and a paired synthesis method applied to carbon dioxide reuse. Background technique [0002] Energy depletion and environmental pollution are the main problems restricting human development in the 21st century. With the consumption of fossil fuels and their combustion, atmospheric CO 2 content continues to increase, search for alternative energy sources and reduce atmospheric CO 2 content is the focus of the researchers. When fuel cells use organic matter as fuel, the emission of carbon dioxide is much smaller than that released during combustion. Catalytic reduction of CO 2 The methods mainly include electrocatalytic reduction, photocatalytic reduction and photocatalytic reduction, in which photocatalytic reduction of CO 2 considered to be one of the most promising methods. Therefore, we hope that...
