A Facile Route to Synthesize Pt-WO3 Nanosheets with Enhanced Electrochemical Performance for HER
摘要
Abstract
Platinum-tungsten trioxide (Pt-WO3) nanosheets were synthesized on nickel foams (NFs) directly.As great conductive networks,NFs substrates could greatly improve the electrode performance of WO3.The modified platinum nanoparticles not only enhanced the electron transformation of catalysts,but also increased the active sites for hydrogen evolution reaction (HER).Pt-WO3/NF revealed a better catalytic activity than WO3/NFs with a smaller Tafel slope (80 mV· dec-1) and a lower overpotential of 72 mV at the current density of 10 mA· cm-2.In addition,Pt-WO3/NF showed great durability and stability during the long-term electrochemical test of 45 h.This work provides a facile strategy of improving transition metal oxides (TMOs) as high activity HER catalysts for promising practical applications.关键词
