Among them developing carbon dioxide reduction reaction is the most crucial part. As a result, making the research into substrates, which catalyze of carbon dioxide reduction reaction and promote the efficiency, is regarded as main purpose. This research uses gold-copper bimetallic nanomaterial as a working substrate, in order to catalyze the electrochemical reaction of carbon dioxide reduction and calculate the Faradic efficiency of carbon monoxide. In the beginning, by using Hydrothermal to synthesize the copper nanoparticles on substrate and test the Faradic efficiency of the sample, the result is only around 1.1%. However, by dropping the Au ion solution on the surface of copper nanoparticles substrate with annealing step to promote Faradic efficiency of the sample without any effects from surfactant. Amazingly Faradic efficiency arises to 28.8%. Keywords: carbon dioxide reduction reaction ; Hydrothermal ; gold-copper bimetallic nanomaterial
