The development of effective methods for the abatement of some harmful pollutants from waste waters and from hydric resources is a challenging task. Nitrogen containing compounds, such as inorganic ammonia, nitrites and nitrates are harmful contaminants for drinking water, inducing acute and/or chronic diseases, especially affecting infants and...

Solar energy, along with other renewable resources, is going to play a key role in waste treatments and CO2 conversion. Photocatalytic technologies can be considered an effective solution for these purposes. This work summarises the setup of two different reactor configurations for two challenging processes: nitrate/ammonia abatement from water...

A sample of mesoporous TiO2 (MT, specific surface area = 150 m2·g−1) and two samples of MT containing 2.5 wt.% Fe were prepared by either direct synthesis doping (Fe2.5-MTd) or impregnation (Fe2.5-MTi). Commercial TiO2 (Degussa P25, specific surface area = 56 m2·g−1) was used both as a benchmark and as a support for impregnation with either 0.8...
