Electrochemical CO₂ reduction reaction catalytic activity of zirconium nitrides synthesized by the urea-glass route using ZrCl₄ as a raw material
The development of electrochemical CO₂ reduction reaction (CO2RR) catalysts is crucial for converting CO₂ into valuable chemicals using surplus renewable energy. Carbon monoxide (CO) is widely studied due to its multiple applications. We prepared ZrN nanoparticles via the “urea-glass route.”, as a novel CO2RR catalyst, This preparation process resulted in the formation of a ZrN-carbon composite. CO2RR tests showed the formation of CO, as well as hydrogen, which was generated as a byproduct of the competing water electrolysis reaction. Despite the relatively low CO efficiency, we successfully confirmed the electrochemical CO2RR activity of the ZrN-carbon composite.
