Effective oxygen evolution reaction (OER) is critically important for the solar-fuel production from water (e.g., water splitting); and at the same time, fast oxygen reduction reaction (ORR) is required for the utilization of hydrogen in polymer electrolyte membrane fuel cell (PEMFC) for automotive. In this regard, development of highly active and acid stable OER and ORR electrocatalysts is at the center of such energy-related research efforts. In this talk, I will present our recent work in two areas. First, I will focus on the design, synthesis and study of the catalytic properties of metal alloy electrocatalysts [1] using in situ liquid transmission electron microscopy (TEM) and temperature-variable environmental TEM [2]. Second, I will discuss the development of non-platinum electrocatalysts for both OER and ORR based on ABOx oxides, including perovskite and other types of ternary compounds [3, 4].
