Cover Story (view full-size image): Replacement of high loadings of platinum is key in development of high efficiency, sustainable Oxygen Reduction Reaction catalysts for PEM fuel cell applications. Recent theoretical investigations have revealed the possibility for small subnanometer metal-decorated graphene systems as possible technologies to achieve such a goal. In this work we examine the effects of pH, solvation, and particle size and support dopant on the performance of such catalysts from a recently developed predictive ORR Volcano Plot for metal decorated graphene. Results point towards conditions where such systems may potentially operate at high performance and using few if any precious metals. View Paper here.
