Ternary Interface of Pt|Few‐Layered N‐rGO|TiN for the Boasting Electrocatalytic Activity in Ethylene Glycol Oxidation
Source abstract
Abstract
Abstract The efficient electrochemical oxidation of ethylene glycol (EG) requires the superior synergism of platinum (Pt) based composites, which depends on the formation of effective interface between the components. In this paper, Pt loaded on co‐supporter of TiN and N‐doped reduced graphene oxide (Pt/TiN @ N‐rGO) composite is obtained by an in situ calcination of TiN @ N‐rGO followed with the targeted growth of Pt nanoparticles at the junction of TiN|N‐rGO. As a result, Pt/TiN @ N‐rGO electrode with medium molar ratio of urea to TiCl4 (R =10) and the ideal ternary interface of Pt|few layered N‐rGO|TiN exhibited exceptionally high catalytic mass activity (343.9 mA mg−1 Pt) and long‐term durability (117 mA mg−1 Pt after continuous 1200 min operation) for EG oxidation in acid, compared to other Pt/TiN @ N‐rGO composites and commercial Pt/C (41.1 mA mg−1 Pt). The promoted performance is attributed to the synergies at ternary interface, involving the highest electrochemically active surface areas due to more exposed active sites of Pt nanoparticles, the best electrical conductivity ascribed to the incorporation of few layered N‐rGO, and excellent CO tolerance with the assistance of TiN.
