Efficient photocatalytic hydrogen production over Ni@C/TiO2 nanocomposite under visible light irradiation

► A novel visible-light-driven Ni@C/TiO2 nanocomposite is first prepared. ► Enhanced visible-light-driven photocatalytic H2 production efficiency with better durability. ► Beneficial for developing panchromatic respondent and low-cost photocatalysts.
