Ordered Mesoporous Cobalt Phosphate with Crystallized Walls toward Highly Active Water Oxidation Electrocatalysts

A hexagonally ordered mesoporous cobalt phosphate (CoPi) material is prepared by a facile one‐pot soft‐templating strategy using cetyltrimethylammonium bromide template. Because of its highly accessible surface area and crystalline framework with abundant active sites, the mesoporous CoPi shows a hi...

Zusammenfassung:A hexagonally ordered mesoporous cobalt phosphate (CoPi) material is prepared by a facile one‐pot soft‐templating strategy using cetyltrimethylammonium bromide template. Because of its highly accessible surface area and crystalline framework with abundant active sites, the mesoporous CoPi shows a high catalytic activity for the oxygen evolution reaction compared to previously reported noble/transition‐metal and nonmetal catalysts.
