Cd0.8Mn0.2S is a ternary particulate chemical substance that faces significant challenges with carrier recombination in the field of photocatalysis. To address this issue, we formed an internal electric and constructed S-scheme heterojunctions using Cu2O nanoparticles, thereby reducing rate photogenerated carriers. We synthesized hydrothermal method, followed by employing ultrasonic self-assembly to closely couple Cu2O. In configuration, acts as electron acceptor donor. The Cd0.8Mn0.2S/Cu2O structure forms tight interface, providing shortest transfer distance for migration. heterojunction strategy effectively lowers reaction barriers facilitates vectorial separation Under 10 W white light illumination, composite photocatalyst demonstrates remarkable hydrogen evolution activity, achieving production 40.06 mmol·g–1·h–1. This interface paves way structural design large-scale application highly active visible photocatalysts.

In addressing the severe energy crisis, adopting efficient and reliable strategies is crucial. Photocatalysis technology, utilizing solar to convert it into hydrogen, offers an effective pathway alleviate issues. this study, we have successfully developed TiO2/CdSxSe1–x-Diethylenetriamine (abbreviated as DETA) nanocomposites with S-scheme heterojunction structure. By precisely adjusting value of x (x = 0, 0.25, 0.50, 0.75 or 1.00), optimized charge transfer process, achieving photocatalytic hydrogen evolution reaction. Specifically, sample containing 20% (in mass) TiO2, denoted 20-TO, exhibited best activity. particular, activity TiO2/CdS0.25Se0.75-DETA 20-TO/CS0.25E0.75) reached 32.7 mmol·g–1·h–1, maintaining high performance over ten consecutive cycles (totaling 40 h). We used electron paramagnetic resonance (EPR), ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS), femtosecond transient absorption (fs-TAS) theoretical calculations comprehensively confirm that heterojunctions in all conform mechanism. This mechanism provides optimal path for transfer. Comparative analysis through revealed efficiency between TO CS0.25E0.75 was highest, which correlates well experimental results evolution. innovative enhances new technologies its
