Abstract

Developing engineering advanced semiconductor materials with low cost and high efficiency have great importance in solar assisted hydrogen production. In this work, well-designed Ru modulated oxygen defective Ti₃AlC₂ MAX multilayers binary cocatalyst with porous g-C₃N₄ has been fabricated through ultrasonic approach. Synergistic effect of Ru/Ti₃AlC₂ enabling proficient charge carrier transportation for significantly enhanced H₂ production. The optimized 3Ru-15Ti₃AlC₂/g-C₃N₄ exhibited 1445 µmol g⁻¹h⁻¹ of H₂ evolution rate which is 7.67 and 16.35 times more than using 15Ti₃AlC₂/CN and CN samples. The obvious augmented H₂ production can be attributed to efficient charges separation with higher light absorption due to Ru/Ti₃AlC₂ binary cocatalyst. The catalyst loading and sacrificial reagents further confirms mass transfer and surface-active sites exposed to light irradiation. This study provides new approach to construct heterojunction of 2D/2D self-assembly, enabling synergistically improved quantum yield with higher cyclic stability and can be further explored in other solar energy assisted applications.
