Nano-ZnO is a potential catalyst material for carbon dioxide electrocatalytic reduction (CO2RR), but its effective Faraday efficiency (FE) is still below 90% and the current density is less than 300 mA cm-2, which is not enough to meet industrial requirements.
A new study published in Chem Catalysis reported on ZnO nanorods for electrocatalytic CO2RR, which after 500°C heat-treatment, achieved the highest oxygen vacancy content, the highest FECO of 98.3%, and a partial current density of 786.56 mA cm-2 in a 3 M KCl electrolyte.
The research was conducted by Prof. Wu Zhonghua and Dr. Xing Xueqing from the Institute of High Energy Physics of the Chinese Academy of Sciences (CAS) and Prof. Han Buxing from the Institute of Chemistry of CAS.
