Enhancement of oxygen reduction activity and stability via introducing acid-resistant refractory Mo and regulating the near-surface Pt content

引用

Journal of Energy Chemistry 2020年第12期29卷 246-252页

作者： Shouquan Feng Jiajia Lu Lin Luo Guangfu Qian Jinli Chen Hanna SAbbo salam JJTitinchi Shibin Yin College of Chemistry and Chemical Enginering.School of Physical Science and Technology.Key Laboratory of New Processing Technology for Nonferrous Metals and Materials State Key Laboratory of Processing for Non Ferrous Metal and Featured MaterialsGuangxi UniversityNanning 530004.GuangxiChina Department of Chemitry University of the Western Cape7535 Cape TownSouth Africa

Although Pt Ni catalyst possesses good oxygen reduction activity, its poor stability is the main obstacle for the commercialization of proton exchange membrane fuel cells(PEMFCs). In this work, we introduce the acid-resistant refractory Mo to enhance the structure stability and modify the electronic structure of Pt in the prepared PtNi catalyst, improving the catalytic activity for oxygen reduction reaction(ORR). In addition, near-surface Pt content in the nanoparticle is also optimized to balance the ORR activity and stability. The electrochemical results show that the alloy formed by Mo and Pt Ni is obviously more stable than the PtNi alloy alone, because the acid-resistant Mo and its oxides effectively prevent the dissolution of Pt. Especially, the Pt3 Ni3 MoN/C exhibits the optimal ORR catalytic performance in O2-saturated 0.1 mol L^(-1) HClO4 aqueous solutions, with mass activity(MA) of 900 m A mg^(-1) Pt at 0.90 V vs. RHE, which is 3.75 times enhancement compared with the commercial Pt/C(240 mA mg^(-1) Pt). After 30 k accelerated durability tests, its MA(690 m A mg^(-1) Pt) is still 2.88 times higher than the pristine Pt/C. This study thus provides a valuable method to design stable ORR catalysts with high efficiency and has great significance for the commercialization of PEMFCs.
