In this study,the double loaded Co-Fe-B@g-C3N4/NF(NF:Ni foam)thin film catalysts were prepared for the first time via chemical deposition method at room temperature.By optimizing the reducing agent concentra-tion to 0.9 mol·L-1,the as-obtained Co-Fe-B@g-C3N4/NF exhibited the twisted ribbon structure with more dis-tinct three-dimensional hierarchy and the smaller particle size,showing the good catalytic property for the hydrolysis of NaBH4 solution.The H2 generation rate of Co-Fe-B@g-C3N4/NF and binary Co-B@g-C3N4/NF under visi-ble light irradiation surpassed the value under natural condition.The apparent activation energy of Co-Fe-B@g-C3N4/NF(45.0 kJ·mol-1)under visible light irradiation was obviously reduced when compared with the natural condition(48.4 kJ·mol-1)and binary Co-B@g-C3N4/NF(60.6 kJ·mol-1)under visible light irradiation.Further-more,the catalytic performance of the optimized Co-Fe-B@g-C3N4/NF thin film catalyst was superior to most of the reported non-noble metal and even noble metal cata-lysts.Hence,it illustrated that the catalytic H2 production performance of Co-Fe-B@g-C3N4/NF thin film was distinctly improved after the introduction of light and multicomponent recombination.
