Ti-based Metal-organic frameworks (Ti-MOF) have been extensively investigated for producing hydrogen via solar water splitting, while their intrinsic activities are still retarded by the poor performance of photocarriers separation and utilization. Herein, a donor-acceptor (D-A) supramolecular photocatalyst is successfully constructed via encapsulating fullerene (C) into MIL-125-NH and meanwhile depositing individual Pt atoms as cocatalyst. The as-prepared C@MIL-125-NH-Pt exhibits remarkable activity in photocatalytic water splitting, with a H formation rate of 1180 μmol g h, which is ∼ 12 times higher than that of the pristine MIL-125-NH.

The effects of heating rate on combustion characteristic are considered. The results showed that the combustion rate of pulverized coal increased and the burnout time decreased under the conditions of an oxygen-enriched atmosphere and high heating rate.

Whereas, nickel phosphides (Ni P ) possess more than ten stoichiometric compositions with different crystalline. Constructing Ni P with well crystalline and revealing their intrinsic catalytic mechanism at atomic/molecular levels remains a great challenge.
