摘要：Metal-organic framework (MOF) based heterojunctions offer a promising strategy for CO2 photoreduction, contributing to carbon neutrality and environmental remediation. However, the precise design and control of these heterostructures remain critical challenges. Herein, we report the precise construction of a heterostructure by integrating 2D ZnIn2S4 nanosheets with NH2-MIL-125(Ti) for efficient CO2 photoreduction in a sacrificial agent-free environment. A comprehensive investigation demonstrates robust interfacial interactions and work function differences between NH2-MIL-125(Ti) and ZnIn2S4, facilitating the formation of an interfacial electric field and enabling the construction of an S-scheme heterojunction. The directional migration of photogenerated charge carriers effectively suppresses their recombination, retaining the strong oxidative and reductive potential of the heterostructure components. In-situ infrared spectroscopy provides concrete evidence that the S-scheme heterojunction significantly enhances the formation of key intermediates, which are crucial for CO generation. The optimized NMT-5@ZIS achieves a CO yield of 17.30 umol g(-1)h(-1) without sacrificial agents, representing 8.6 and 6.6-fold improvements over pristine NH2-MIL-125(Ti) and ZnIn2S4, respectively. This work bestows an innovative insight into the construction of MOF-based S-scheme heterojunctions, opening new avenues for practical applications in energy storage and photocatalysis.
