Abstract This work focuses on 3D, self‐supported, nanofibrous TiO 2 structures (nanogrids) prepared using blend electrospinning. The presence of anatase and brookite phases in Cu‐doped nanogrids significantly enhances the photocatalytic properties titania system. absorption edge shifts to visible due narrowed bandgap efficient separation photogenerated charge carriers facilitated by Cu doping. phase further contributes enhanced performance, reducing electron–hole recombination. A wide range characterization techniques, including cyclic voltammetry chronoamperometry studies which show that doped TiO₂ sample generates a significant photocurrent under light, are employed elucidate role doping enhancing light efficiency nanogrids, offering valuable insights for developing advanced photochemical catalysts environmental energy applications. studied here far superior P25 Degussa activated natural sunlight do not require filtration system remove nanoparticles from water. These self‐supported offer all benefits nanomaterials while suffering none their drawbacks.

The photoreduction of CO 2 has attracted extensive attention as a promising solution to global warming. In this study, Cu‐modified TiO (B) (CuTB) nanoflowers with oxygen vacancies (OVs) are designed and synthesized via hydrothermal treatment photodeposition promote the reactivity selectivity reduction under visible light. CH 4 yields sample Cu 1 TB‐1.5 light 5.72 0.02 μmol g −1 h , wherein yield was 15.5 times that TB; its is 99.6%, cycling stability excellent. OVs can broaden absorption TB region, promotes photoinduced electron transfer from species act an active center. synergistically enhance charge separation, adsorption, conversion. facilitates formation intermediate COOH* during photocatalytic process, thus improving CO. This research provides unique idea for development novel highly selective photocatalysts.

It is imperative to develop affordable multi-functional catalysts based on transition metals for various applications, such as dye degradation or the production of green energy. For first time, we propose a simple chemical bath method create SnO2-BiOBr-rGO heterojunction with remarkable photocatalytic and electrocatalytic activities. After introducing graphene oxide (GO) into SnO2-BiOBr nanocomposite, charge separation, electron mobility, surface area, electrochemical properties were significantly improved. The X-ray diffraction results show successful integration GO nanocomposite. Systematic material characterization by scanning transmission microscopy showed that photocatalysts are composed uniformly distributed SnO2 nanoparticles (∼11 nm) regular nanosheets BiOBr (∼94 rGO. photocatalyst has outstanding activity when it comes reducing variety organic dyes like rhodamine B (RhB) methylene blue (MB).
