Effect of Co-catalyst (CuO, CoO or NiO) on Bi2O3–TiO2 Structures and Its Impact on the Photocatalytic Reduction of 4-nitrophenol
CoO, NiO or CuO oxides were employed as co-catalysts on Bi2O3–TiO2 (BT) structure in the photocatalytic reduction of 4-nitrophenol under UV light irradiation. The intimate contact between the co-catalysts and bas...

Effect of Pd and Cu co-catalyst on the charge carrier trap**, recombination and transfer during photocatalytic hydrogen evolution over WO3–TiO2 heterojunction
Co-catalysts are well known for improving the charge carrier’s separation and transfer to species in solution, and hence, the photocatalytic hydrogen production. Thus, in this work, the effect of loading Cu an...

Photocatalytic degradation of 2,4-dichlorophenol on ZrO2–TiO2: influence of crystal size, surface area, and energetic states
ZrO2–TiO2 heterostructure with 5 mol% of ZrO2 was synthesized by the sol–gel method and calcined at different temperatures (300–600 °C). The photocatalysts were characterized by thermal analysis, X-ray diffractio...

Rapid breakdown anodization to obtain nanostructured TiO2 powders for photocatalytic hydrogen generation
TiO2 is widely used for photocatalytic applications, and several methodologies are employed to obtain nanostructured TiO2 powders with a wide range of morphologies that tune its performance; however, rapid breakd...

Energetic states in SnO2–TiO2 structures and their impact on interfacial charge transfer process
In this paper, core(SnO2)@shell(TiO2) structures with different SnO2:TiO2 molar ratios were obtained by direct hydrolysis of titanium isopropoxide on SnO2 nanoparticles, forming a composite that provided a direct...
