The onset potential for H production from neutral water (pH 7) catalyzed by a platinum(ii) porphyrin (PtP-py) modified TiO electrode positions very close to the standard water reduction potential (less than 50 mV). H production is driven by the conduction band edge potential of TiO at the PtP-py-modified TiO cathode.

The surface of titanium foil can be modified by heating in the air, in a N flow, and in an NH flow. Upon heating in the air, the elemental Ti gradually transforms to TiO at 550 °C and to rutile TiO at above 700 °C. Treatment in a N flow leads similarly to TiO at 600 °C and TiO at 700 °C, although the overall reaction is slower.

This work proposes dye-sensitized solar cells (DSSCs) with various photoanode designs. A hydrothermal method is used to synthesize hydrangea-shaped TiO (H-TiO) aggregates. The X-ray diffraction (XRD) pattern of H-TiO reveals only an anatase phase.

This study investigates the rheological behavior of oil well cement pastes (OWCPs) modified with core/shell TiO@SiO (nTS) nanoparticles and polycarboxylate-ether (PCE) superplasticizers at different temperatures (25, 45, and 60 °C). Results show that nTS particles increased static and dynamic yield stresses and the apparent viscosity of the cement slurries due to an increased solid volume fraction and reduced free water availability. The increase in the slurry dispersion by adding PCE superplasticizers enhanced the effect of the nanoparticles on the rheological parameters.

Catalytic oxidation of formaldehyde (HCHO) is a highly effective method for indoor HCHO removal. However, many aspects of the catalytic mechanism remain unclear, making the optimization of catalysts largely empirical. Herein, we report a coupled experimental and computational study of Pt/TiO catalysts, with special focus on the functional roles of surface oxygen vacancies and hydroxyl groups in the catalytic oxidation of HCHO.
