Transition metal phosphides as promising noble metal free cocatalysts are gaining increasing interest for hydrogen generation and other energy conversion reactions. The present study reports a new Fe2P/g‐C3N4hybrid for efficient photocatalytic hydrogen generation by water splitting under visible light irradiation. The H2production rate obtained using this system is approximately 15 times higher than that obtained using pure g‐C3N4, and is comparable with that of Pt/g‐C3N4under the same conditions. According to detailed studies using UV/Vis diffuse reflectance and photoluminescence spectroscopies as well as photoelectrochemical measurements, the reason for the high efficiency of the Fe2P/g‐C3N4hybrid is due to a highly effective separation and low recombination rate of photogenerated electrons and holes rather than absorption under visible light. The present study reports a promising non‐toxic photocatalyst with low cost and high natural abundance for improving photocatalytic H2generation.
