Water splitting is an important technology for green hydrogen production. However, the sluggish kinetics of the anodic oxygen evolution reaction limit device performance. Furthermore, under acidic conditions, sparse and expensive iridium-based catalysts are required. In the May issue of Chem, Lu et al. explored mild electrochemical oxidation treatments to transform graphite flakes into promising oxygen evolution reaction (OER) catalysts.
