Mo–P sites boosting interfacial charge transfer of 2D/3D MoS2/TiO2 heterostructure for efficient photocatalytic hydrogen production and chromium(vi) reduction

“…Photocatalytic hydrogen production from water splitting and the removal of heavy metal ions from wastewater via solar energy are highly promising strategies for addressing both energy and environmental issues. 1–3 Among various semiconductor materials, TiO 2 has been widely employed for hydrogen energy production 4,5 and wastewater treatment 6 due to its strong reducing power, excellent chemical stability, and non-toxic nature. 7,8 Despite its favorable thermodynamic reducing power, TiO 2 faces challenges in practical applications due to rapid recombination of photo-excited carriers and poor visible light response.…”
