Copper nanoparticles sensitized TiO2 nanotube arrays electrode with enhanced photoelectrocatalytic activity for diclofenac degradation

Enhanced photocatalytic, electrochemical and photoelectrochemical properties of TiO2 nanotubes arrays modified with Cu, AgCu and Bi nanoparticles obtained via radiolytic reduction

“…Additionally, in the case of copper nanoparticles the small contrast between Cu and TiO 2 can be a factor that hinders observation [29], [55]. In contrast, another deposition techniques, such as chemical reduction [47], [48], photodeposition [38], [40], [71], electrodeposition [42] led to the formation of larger nanoparticles which were present also on the top surface of nanotubes and could be easily observed using SEM technique.…”

Chemical bath deposition of well-aligned ZnO nanorod arrays on Ag rods for photoelectrocatalytic degradation of rhodamine B

“…One‐dimensional (1D) nanostructures are emerging as a promising photoelectrode owing to their fast electron transport, large surface‐to‐volume ratio and providing a pathway for electron transportation. To date, considerable studies of PEC on different metal oxides with 1D nanostructures were carried out, such as TiO 2 and ZnO .…”

Photoelectrochemical performance of birnessite films and photoelectrocatalytic activity toward oxidation of phenol

“…In order to increase the photocatalytic activity under visible irradiation, extensive studies have focused on doping metals (Fe, Cu, Cr, etc. ) or non-metals (carbon and nitrogen) into TiO 2 to narrow the bandgap of TiO 2 (Zhang and Lei, 2008;Hua et al, 2015;Yang et al, 2014;Chen et al, 2009;Lan et al, 2013). As an alternative, some novel photocatalysts with response to visible light, such as Fe 2 O 3 , WO 3 and metal-free g-C 3 N 4 , have been developed (Zhang et al, 2010;Hepel and Hazelton, 2005;Cheng et al, 2007;Shinde et al, 2013Shinde et al, , 2016.…”
