الملخصDirect methanol fuel cells (DMFCs) proved to be promising alternative for renewable energy resources. There are several factors involved for the hindrance of their commercialization. Herein, the alteration in catalyst's chemistry has been mainly focused to improve the performance of DMFCs. Mesoporous carbon supported bimetallic combinations of Pt with metallic oxides such as, Pt/CeO2-MC, Pt/PrO2-MC, Pt/NdO2-MC, and Pt/SmO2-MC were synthesized and tested as methanol electro-oxidation anode catalysts. These high-surface area anodes were synthesized by impregnation with Pt to form the desired methanol electro-oxidation catalysts. The as-prepared catalysts were characterized using XRD, BET surface area, and EDS. High surface areas of 684-778m2/g were achieved for the CeO2-MC, PrO2-MC, NdO2-MC, and SmO2-MC, which enabled excellent dispersion of the Pt nanoparticles onto their surfaces. The Pt/CeO2-MC catalyst showed the highest activity for methanol electro-oxidation, which is about 3.5% more than that of the commercial Pt-Ru/C (E-TEK) catalyst. In addition, the prepared catalysts showed significant stability and durability.
راعي المشروعThe support of the Center for Advanced Materials (CAM), Qatar University through project number QUUG-CAM-CAM-15\16-2 and Center of Excellence in Renewable Energy at King Fahd University of Petroleum & Minerals (KFUPM) is highly appreciated. Mr. Mukhtar Bello also appreciates the support of Ahmadu Bello University, Zaria, Nigeria for the study fellowship awarded to him.
