TNR@Ni-foam structures were prepared by an alkaline hydrothermal method in autoclave a strongly medium (10 M NaOH) at 150 °C with further acid washing (0.1 HNO3) and second treatment 180 °C. Two TiO2 samples used for preparation: anatase P25 of mixed rutile phases. After the first step treatment, layered titanate structure was obtained (Na2Ti3O7). Acid caused substitution Na+ H+ launched formation TNR. °C, optimal quantity mL per 0.75 g TiO2), titania crystallized to phase small quantities brookite rutile. The from exhibited more than those based on precursor. morphology observed SEM. composites tested acetaldehyde photodegradation (240 ppm air) during continuous flow gas (5 mL/min) through reactor coupled FTIR. most active P25, which had crystalline contained lowest residue Na species.

TiO2 was loaded on the porous nickel foam from suspended ethanol solution and used for photocatalytic removal of NOx. Such prepared material heat-treated at various temperatures (400–600 °C) to increase adhesion with support. Obtained TiO2/nickel samples were characterized by XRD, UV–Vis/DR, FTIR, XPS, AFM, SEM, nitrogen adsorption 77 K. Photocatalytic tests NO abatement performed in rectangular shape quartz reactor, irradiated top UV LED light an intensity 10 W/m2. For these studies, a laminar flow air (1 ppm) applied under relative humidity 50% temperature 28 °C. Concentrations both NO2 monitored chemiluminescence analyzer. The species surface determined FTIR spectroscopy. Performed studies revealed that increased heat treatment improves substrate, decreases porosity, causes hydroxyl alcohol groups titania surface. less hydroxylated is more vulnerable species, whereas presence OH enhances nitrate ions. Adsorbed upon irradiation moisture undergo photolysis NO2. As consequence, released into atmosphere, efficiency NOx decreasing. conversion higher sample heated 400 °C than 600 °C, although coverage lower former one. It stated defects (Ti3+) low its heating formation radicals, which take part oxidation. Contrary that, through ilmenite structure (NiTiO3) inhibits activity.
