Unveiling efficient S-scheme charge carrier transfer in hierarchical BiOBr/TiO heterojunction photocatalysts.

The construction of a potential heterojunction catalyst with proper interface alignment has become a hot topic in the scientific community to effectively utilize solar energy. In this work, a one-dimensional TiO nanofiber/BiOBr S-scheme heterojunction was synthesized, and charge carrier dynamics within the interface channel were explored. In addition, we incorporated mixed phase TiO with point defects and oxygen vacancies, which greatly promoted the initial band edge shift from the UV region.

MXene-Derived TiO/Starbon Nanocomposite as a Remarkable Electrode Material for Coin-Cell Symmetric Supercapacitor.

In this study, the synthesis of a MXene (TiCT)-derived TiO/starbon (M-TiO/Starbon-800 °C) nanocomposite using a facile calcination method is explored. High-temperature exposure transforms layered TiCT into rod-like TiO and starbon into amorphous carbon. The resulting M-TiO/Starbon-800 °C nanocomposite exhibits a significantly larger surface area and pore volume compared to its individual components, leading to superior electrochemical performance.
