Mechanistic insights into 2,4-D photoelectrocatalytic removal from water with TiO<inf>2</inf> nanotubes under dark and solar light irradiation
2021, Journal of Hazardous MaterialsCitation Excerpt :The fact that in region 1 the reactant removal rate is not modified by the presence of FA, indicates the reactions of 2,4-D removal and FA oxidation are independent: two different sites could be involved in the two reactions. In a previous work on oxidation of FA with Degussa P25, two kinds of sites were mainly involved with different adsorption strength (Muggli and Backes, 2002). In particular, oxygen vacancies, identifiable as Ti+3, which normally accounts for about 10–12% of the defectivity (Wendt et al., 2005), are likely to accommodate the dissociated form of the molecules (i.e. FA−), while the undissociated form was more weakly linked on Ti+4 sites (Muggli and Backes, 2002).
Reduced graphene oxide/TiO<inf>2</inf> nanotube composites for formic acid photodegradation
2017, Applied Catalysis B: EnvironmentalStructure-dependent photocatalytic decomposition of formic acid on the anatase TiO<inf>2</inf>(101) surface and strategies to increase its reaction rate
2016, Journal of Power SourcesCitation Excerpt :found that its PCO rate can be enhanced by a factor of two by coadsorbed water molecules. However, Muggli et al. [8] suggested that the effect of water on formic acid is to displace them. This is in consistent with the TPD measurement by Miller et al. [9] which found a decrease of the amount of adsorbed formic acid after adsorption of water.
