The quick recombination of photogenerated carriers and the high surface reaction barrier are two important aspects influencing photocatalytic hydrogen generation. In this paper, a sulfur vacancy-modified two-dimensional (2D) fluorinated-TiO2 nanosheet/Mn0.2Cd0.8S (F-TiO2/MCS) S-scheme heterojunction was synthesized by simple hydrothermal method to accelerate electron transfer. formation an between MCS nanoflowers 2D F-TiO2 enhances efficacy generation facilitating separation electron–hole pairs. Meanwhile, vacancies F-TiO2/MCS change local electronic structure capturing electrons, resulting in evolution rate for 3197 μmol g–1 h–1, which is 4.42 times greater than that pure MCS. Experimental measurements density functional theory (DFT) calculations show mutual synergy not only provides abundant H2 adsorption active sites but also promotes interfacial charge migration, improves performance composite. This work holds significance production heterojunctions.
