Frontispiece: Nanoscale Perovskites as Catalysts and Supports for Direct Methanol Fuel Cells

Perovskite oxides with a chemical formula of ABO3 (in which A=either alkaline, alkaline‐earth, or rare‐earth metal ions and B=d‐block transition metals) have been widely investigated because of their inherently unusual and simultaneously desirable electronic and magnetic properties. These materials may act as cost‐effective, more earth‐abundant, and high‐performance alternatives to commercial Pt/Pd‐based catalysts for electrocatalysis. In their Review article on page 7779 ff., S. S. Wong et al. highlight advances in the use of perovskite metal oxides as both catalysts and catalyst supports towards the oxygen reduction reaction (ORR) and the methanol oxidation reaction (MOR) within a direct methanol fuel cell (DMFC) configuration.
