Elongated titania nanostructures as efficient photocatalysts for degradation of selected herbicides
(Applied Catalysis. B: Environmental, 2014)
Titanium dioxide nanotubes (TNT) were synthesized via hydrothermal method and calcined at various temperatures. The obtained calcined TiO2 nanomaterials with specific elongation orientation were characterized by transmission ...
Photocatalytic activity of synthesized nanosized TiO2 towards the degradation of herbicide mecoprop
(Applied Catalysis. B: Environmental, 2004)
The kinetics and possible mechanism of the photocatalytic degradation of herbicide mecoprop, in UV illuminated aqueous colloids of synthesized nanosized TiO2 were investigated. The rate of degradation was studied by H-1 ...
RuxTi1-xO2 as the support for Pt nanoparticles: Electrocatalysis of methanol oxidation
(Applied Catalysis. B: Environmental, 2015)
Two binary Ru-Ti oxides, Rum Ti0.9O2 and Ru0.7Ti0.3O2, were synthesized by the sol-gel method and used as an electrocatalyst support. The system was characterized by XRD, EDS, TEM and cyclic voltammetry. The Rum Ti0.9O2 ...
Synthesis and characterization Pt nanocatalysts on tungsten based supports for oxygen reduction reaction
