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.

self-assembly of molybdenum carbide and iron carbide heterostructures on N-doped carbon for an efficient oxygen reduction reaction.

Identifying highly stable, cost-effective, platinum-free, and efficient electrocatalysts for the oxygen reduction reaction (ORR) remains a formidable challenge. The ORR is important for advancing fuel cell and zinc-air battery (ZAB) technologies towards cost-efficiency and environmental sustainability. This work presents the utilization of economically viable materials through a straightforward synthesis process, exhibiting the development of efficient MoC/FeC-NC catalysts ingeniously derived from phosphomolybdic acid (PMA) and iron phthalocyanine (FePc).
