Low‐Temperature Construction of a Ti–O–C‐Linked S‐Scheme Heterojunction for Efficient Visible‐Light Photocatalytic Redox Reactions

possesses a small size and high surface area, contributing to high electron density and abundant active sites. Meanwhile, Y-CD not only extends visible-light absorption but also induces electronic states and intermediate energy levels that act as an energy-level bridge, facilitating S-scheme charge transfer. Driven by the built-in electric field and interfacial interactions, this pathway significantly promotes carrier separation and migration, thereby enhancing photocatalytic performance. This work demonstrates a sustainable route for developing high-performance photocatalysts for wastewater treatment.
