A Comparative Study of Microcystin-LR Degradation by UV-A, Solar and Visible Light Irradiation Using Bare and C/N/S-Modified Titania

“…Indeed, it is known that the pH value might control the surface characteristics and the size of aggregated nanoparticles resulting in higher content of formed hydroxyl radicals, and improved adsorption capacity of organic pollutants onto a photocatalysts surface [67]. Therefore, our results demonstrating the role of preparation pH value for controlling of the phase composition and boosting the photocatalytic activity of TiO 2 nanoparticles is consentient with previous reports [68,69]. It was also proposed that the highest activity of the co-modified TiO 2 photocatalyst (CNS-S4) results from a non-metals presence, which could act as active sites for efficient MC-LR adsorption and degradation [51][52][53][54][55].…”

Tailored synthesis of anatase–brookite heterojunction photocatalysts for degradation of cylindrospermopsin under UV–Vis light

“…In a typical photocatalytic degradation experiment, CYN at an initial concentration of 1µM was degraded under UV-Vis irradiation with as-prepared TiO 2 catalysts (0.25 g L -1 ). The degradation percentage (DP %) could be estimated as follows [32,33]:…”

Biomass-derived multifunctional TiO2/carbonaceous aerogel composite as a highly efficient photocatalyst

“…However, the frequent occurrence of dyes and antibiotics in the aqueous environment has led to the emergence of environmental issues, which pose a threat to human health. Therefore, many studies have chosen them as the representative organic pollutants to evaluate photocatalytic degradation over as-prepared composites, [52][53][54] and have generally chosen concentrations of 10 mg L À1 . In this work, we chose a relatively high simulated pollutant concentration of 40 mg L À1 to conrm the photocatalyst performance.…”
