A nano AuTiO 2−x composite with electrochemical characteristics of under-potential deposition of H (H-UPD) as a highly efficient electrocatalyst for hydrogen evolution

An obvious H-UPD for a nano AuTiO 2−x composite has been found for the first time in terms of the electrochemical characteristics of the Au composite. The electronic effect between Au and TiO 2 and the oxygen vacancy defect would change the adsorption energy of H and HER activity. The HER activity o...

Description
Summary:An obvious H-UPD for a nano AuTiO 2−x composite has been found for the first time in terms of the electrochemical characteristics of the Au composite. The electronic effect between Au and TiO 2 and the oxygen vacancy defect would change the adsorption energy of H and HER activity. The HER activity of the AuTiO 2−x electrode is 6.44 times that of the Au electrode.
