Activated carbon fiber (ACF) was modified by Zn(NO), ZnCl, and Zn(CHCOO)), respectively, and then, TiO was loaded on the modified ACFs. The adsorption and photocatalysis performance were explored through the removal of toluene, and TiO/ACF- modified by Zn(CHCOO)) with the best toluene degradation performance was selected. The characterization results of a scanning electron microscope (SEM), X-ray diffraction spectra (XRD), and Fourier transform infrared spectrometer (FTIR) indicated that the samples were rough, and TiO was mainly loaded on the surface containing large amount of oxygen-containing functional groups in anatase phase. An ultraviolet-visible diffuse reflectance spectrophotometer (UV-vis DRS) revealed that the catalyst enhanced the light response range. The photoelectric chemical experiment results demonstrated that the modified ACFs remarkably improved the charge transmission and the separation efficiency of electrons and holes. The adsorption saturation time reached 40 h and toluene photodegradation rate was 70%. Four toluene degradation intermediate products were determined by GC-MS, and the removal mechanism of toluene by TiO/ACF- was discussed.

As a sustainable alternative technology to the cost- and energy-intensive Haber-Bosch method, electrochemical nitrogen (N) reduction offers direct conversion of N to NH under ambient conditions. Direct use of noble metals or non-noble metals as electrocatalytic materials results in unsatisfactory electrocatalytic properties because of their low electrical conductivity and stability. Herein, three-dimensional flexible carbon nanofiber (CNF/TiO@CoS) nanostructures were prepared on the surface of CNF by using electrospinning, a hydrothermal method, and in situ growth.

Polydispersed Ag species-modified TiO samples with abundant oxygen vacancies were successfully prepared through the calcination of atomically precise Ag nanocluster-loaded TiO at an optimal temperature under a nitrogen atmosphere. The ligands of the Ag nanoclusters are removed by extracting lattice oxygen from TiO during the calcination, leading to the formation of CO, SO, and HO vapor. This process simultaneously induces Ag species sintering on the surface of TiO.

Photocatalytic oxidation is considered to be a highly promising technology for indoor formaldehyde (HCHO) abatement. However, powdered photocatalysts encounter practical challenges due to their recycling difficulties and propensity for aggregation. In this study, we developed a CuO/OVs-TiO photocatalyst dispersion using various physical and chemical methods, which could be stabilized for an extended period.

A TiO/CdS heterostructure has been widely investigated as a potential photoanode for photoelectrochemical (PEC) water splitting for hydrogen evolution. However, the efficiency and stability still remain challenging due to the sluggish reaction dynamics for water oxidation and easy photocorrosion of CdS. Here we report a ternary TiO/CdS/IrO heterostructure with IrO as a hole transport layer for PEC glycerol oxidation coupled with hydrogen evolution.

Fluorescence spectroscopy employed to compute the antibacterial potential of pure ZnO and Titania (TiO) loaded ZnO (TiO: 2%, 4%, 6%, and 8%) electrospun nanofibers. The study of electrospun nanofibers followed by their structural, morphological and antibacterial properties has been revealed through fluorescence spectroscopy. X-ray diffraction (XRD) analysis of nanofibers calcinated at 600 °C revealed the presence of polycrystalline wurtzite hexagonal crystallographic planes of ZnO with preferred orientation along (101) direction.
