N- and Mo-doping Bi2WO6 in photocatalytic water splitting

► Nitrogen-doping improves oxidation rate of oxygen and reduction hydrogen power. ► Mo dopant can improve the limited solubility of N dopant in the N/Mo-codoped Bi2WO6. ► N/Mo-codoping can improve efficiency of Bi2WO6 in photocatalytic water-splitting.
