Electrocatalysis: Mo Doping Induced More Active Sites in Urchin-Like W18O49Nanostructure with Remarkably Enhanced Performance for Hydrogen Evolution Reaction (Adv. Funct. Mater. 32/2016)

On page 5778, J.-G. Wang and co-workers present a 3D urching-like Mo-W18O49 catalyst that exhibits a small onset potential and Tafel slope in catalyzing hydrogen evolution reaction (HER). Synergies between an increased amount of active sites and activity improvement by Mo doping as well as a high surface area cause the performance enhancement. Scalable, highly efficient Mo-W18O49 HER electrocatalysts obtained via this simple doping strategy are promising for future water splitting devices.
