摘要
Hydrogen is a clean energy and the development of effective catalysts for green hydrogen from water splitting has garnered increased attention. Herein, a state-of-the-art strategy for constructing a FLP/MOF heterostructure by depositing NH 2 -functionalized MIL-125(Ti) onto few-layered phosphorene (FLP/MOF) nanosheets was developed for H 2 production evolving from water splitting. Upon the activation of MOF, the pore texture shifts from a microporous to mesoporous nature with narrow slit-like pores, indicating the emergence of more active sites. Moreover, the XPS and optical results elaborate the significant interaction between the MOF and FLP. The reduction of Ti 4+ to Ti 3+ in FLP/MOF contributed from the ligand-to-metal charge transfer results in the strong interaction between FLP and MOF. Moreover, the hydrogen production rate increases 2.6 and 5.7 times compared to those pure MOF and FLP, respectively, and the highest hydrogen evolution rate of 1617 μmol g −1 h −1 by FLP-1/MOF can be achieved. The hydrophilicity of NH 2 -MIL-125 promotes water adsorption, and FLP facilitates electron transfer to further accelerate the hydrogen evolution rate. Results highlight the superiority of fabricating FLP/MOF-based PEC nanocatalysts for green H 2 production, which can offer new perspectives for improving PEC hydrogen evolution.
