Photocatalytic activities of ultra-small β-FeOOH and TiO 2 heterojunction structure under simulated solar irradiation

Charge transfer between biogenic jarosite derived Fe 3+ and TiO 2 enhances visible light photocatalytic activity of TiO 2

“…Maleic acid was used as an organic linker. The method of preparation for heterojunction structure was adopted from previous study (Rawal et al, 2009;Chowdhury et al, 2015;Kim et al, 2009;Oputu et al, 2015). Four different ratios (W/W) of TiO 2 /jarosite composite namely 25/75, 50/50, 75/25 and 80/20 were prepared.…”

“…(5)). To prove the existence of TiO 2 valence band hole and its transfer to jarosite derived Fe 3+ , coumarin (COU) was used as a fluorescence probe (Xiang et al, 2011;Chowdhury et al, 2015). COU can react with OHU to generate highly luminescence 7-hydroxycoumarin (7-HC) as shown in Eq.…”

A novel β-FeOOH/NiO composite material as a potential catalyst for catalytic ozonation degradation of 4-chlorophenol

“…The method of preparation for β-FeOOH/NiO composite structure was adopted from previous study 16,18 . Three different mol % loading of β-FeOOH (2, 5 and 10%) on NiO was prepared.…”

Photocatalytic Behavior of Water-Based Styrene-Acrylic Coatings Containing TiO2 Sensitized with Metal-Phthalocyanine Tetracarboxylic Acids

“…Therefore, among research related to optimize nanoparticle's shape, size, and morphology [12][13][14][15] a great deal of attention was paid to the modification of titania-based photocatalyst with metal and non-metal atoms to shift the optimum range of action to the visible domain of the spectrum [16], but the recombination of photo-generated species remains an important challenge. Another strategy is related to the development of heterojunctions between semiconducting oxides and different photosensitizing materials [17][18][19].…”
