On the photocatalytic properties of elongated TiO2 nanoparticles for phenol degradation and Cr(VI) reduction

Photoelectrochemical cell for simultaneous electricity generation and heavy metals recovery from wastewater

“…For this purpose, advanced oxidation processes including photocatalysis have been investigated for the effective removal of metal ions [6][7][8]. In photocatalysis the absorption of photons by a semiconductor photocatalyst generates electron-hole pairs [9] and in turn highly reactive radical species, which lead to the oxidation of organic wastes [10].…”

Photoelectrochemical properties of MoO2 thin films

“…The photoelectrolysis [1,2], photocatalysis [3,4], and photoelectrochemical power conversion [5] processes have been attracting a considerable interest for decade. The primary problem of these processes is to select an efficient and stable photoelectrode.…”

“…The literature survey revealed that the photocatalytic and photoelectrochemical behavior of various transition metal oxides such as TiO 2 [3,6], WO 3 [4,7], ZnO [8,9], CuO [10,11], and Fe 2 O 3 [12] had been well studied. The low solar-toenergy conversion efficiency of these oxides is a major restrict for their practical application, and an urgent search of new materials for a better light to chemical conversion efficiencies is still under investigation.…”

Effective catalytic reduction of Cr(VI) over TiO2 nanotube supported Pd catalysts

“…In fact, previous studies reported enhanced Cr(VI) reduction in photocatalytic reaction by the surface acidity of layered compound and titanate nanofiber [7,44]. Additionally, compared with Pd/TiO 2 the Pd in Pd/TNT was better dispersed, favoring contact of the reactant with both the active Pd site and the acid site of the support simultaneously.…”
