Activation and stabilization of gallium arsenide anode in an aqueous photoelectrochemical cell
(
Elsevier B.V.
, 2003 , Article)
The formation of a porous layer on the surface of gallium arsenide anode, n-GaAs, increases photogenerated currents significantly. This layer was formed as a result of an anodic polarization of illuminated n-GaAs in acidified ...
Photocatalytic degradation of methyl orange as a model compound
(
Elsevier
, 2002 , Article)
Titanium dioxide (TiO2) was used as a photocatalyst for the detoxification of water containing methyl orange (MO), which was used as a model compound. Solar radiation was used as an irradiation source. It was found that ...
