Ti4O7/g‐C3N4 Nanocomposites as an Excellently Durable and Active Electrocatalyst for Oxygen Reduction Reaction
Source abstract
Abstract
Abstract In this paper, Ti4O7/g‐C3N4 nanocomposites are successfully prepared by hydrothermal and carbothermal reduction reaction. It shows large specific surface area and electrochemical active surface area (ECSA = 187.82 cm2) and can act as an oxidation reduction reaction catalyst. Compared with commercial Pt/C catalyst, Ti4O7/g‐C3N4 nanocomposites show good catalytic activity in alkaline medium. The peak potential, onset potential, and half‐wave potential are 0.74 (versus RHE), 0.96 (versus RHE), and 0.74 V (versus RHE), respectively. It is worth mentioning that Ti4O7/g‐C3N4 catalyst shows better methanol tolerance and cycle stability than commercial Pt/C catalyst. The relative current density attenuation is less than 30% after a long cycle of 24 h.
