TiO was loaded on the porous nickel foam from the suspended ethanol solution and used for the photocatalytic removal of NO. Such prepared material was heat-treated at various temperatures (400-600 °C) to increase the adhesion of TiO with the support. Obtained TiO/nickel foam samples were characterized by XRD, UV-Vis/DR, FTIR, XPS, AFM, SEM, and nitrogen adsorption at 77 K.

The photocatalytic decomposition of ethylene was performed under UV-LED irradiation in the presence of nanocrystalline TiO (anatase, 15 nm) supported on porous nickel foam. The process was conducted in a high-temperature chamber with regulated temperature from ambient to 125 °C, under a flow of reacted gas (ethylene in synthetic air, 50 ppm, flow rate of 20 mL/min), with simultaneous FTIR measurements of the sample surface. Ethylene was decomposed with a higher efficiency at elevated temperatures, with a maximum of 28% at 100-125 °C.

This study presents a relatively low-cost method for modifying TiO-based materials for photocatalytic bacterial inactivation. The photocatalytic inactivation of Gram-negative () and Gram-positive () bacteria using modified sulphated TiO was studied. The modification focused on the reduction of TiO by ammonia agents and hydrogen at 400-450 °C.

Acetaldehyde decomposition was performed under heating at a temperature range of 25-125 °C and UV irradiation on TiO doped by metallic Ni powder and TiO supported on nickel foam. The process was carried out in a high-temperature reaction chamber, "The Praying Mantis", with simultaneous in situ FTIR measurements and UV irradiation. Ni powder was added to TiO in the quantity of 0.

Preparation of TiO using the hydrothermal treatment in NHOH solution and subsequent thermal heating at 500-700 °C in Ar was performed in order to introduce some titania surface defects. The highest amount of oxygen vacancies and Ti surface defects were observed for a sample heat-treated at 500 °C. The presence of these surface defects enhanced photocatalytic properties of titania towards the deactivation of two bacteria species, and under artificial solar lamp irradiation.
