Interface engineering of snow-like Ru/RuO2 nanosheets for boosting hydrogen electrocatalysis
文献摘要：
Ru has recently been regarded as a promising catalyst for hydrogen oxidation reaction(HOR)and hydro-gen evolution reaction(HER)due to its similar binding energy towards*H but lower price compared to Pt.Nevertheless,the quest of high-efficiency Ru-based catalysts for HOR and HER is driven by the current disadvantages including low activity and unsatisfactory stability.Herein,we have fabricated and engi-neered two-dimensional(2D)Ru-based snow-like nanosheets with Ru/Ru02 interface(Ru/Ru02 SNSs)via a post-annealing treatment.Detailed characterizations and theoretical calculations indicate that the interfacial synergy,which is dependent on the temperature for annealing,can alter the hydrogen binding energy(HBE)and hydroxide binding energy(OHBE),as a result of the enhanced HOR and HER performance.Impressively,the optimal Ru/Ru02 SNSs display a mass activity of 9.13 A mgRu-1 at an over-potential of 50 mV in 0.1 mol L-1 KOH for HOR,which is 65,304,and 21 times higher than those of Ru SNSs(0.14 A mgRu-1),RuO2 SNSs(0.03 A mgRu-1),and commercial Pt/C(0.43 A mgRu-1),respectively.Moreover,Ru/Ru02 SNSs display improved HER activity with a low overpotential of 20.2 mV for achieving 10 mA cm-2 in 1 mol L-1 KOH.This work not only provides an efficient catalyst for HOR and HER,but also promotes fundamental research on the fabrication and modification of catalysts in heterogeneous catalysis.
