Au/Al 2 O 3 , TiO 2 , SiO 2 , MgO preparation by DPU An aqueous solution of HAuCl 4 (400 mL) with a concentration of 5 × 10 −4 M in an amount corresponding to the final Au loading of approximately 2 wt% was mixed with urea (Sigma
Effect of protonation and deprotonation on surface charge density of Nb2O5
A thermodynamic approach
metallic species as V, Cr, Mo, etc [ 2 – 7 ]. Because of its band gap energy (3.4 eV) near semiconductors sensibilized of UV radiation like as TiO 2 , ZnO, Nb 2 O 5 can be applied in photodegradation of organic wastewaters (pesticides, industrials
energy conversion [ 1 – 7 ]. Among photocatalysts, TiO 2 has received the most attention as a photocatalytic material because of its superior photocatalytic activity, chemical stability, low cost, and nontoxicity [ 8 , 9 ]. A major drawback of TiO 2 is
2 and three TiO 2 Layers). Samples were dried at 100 °C for 1 h and were heated at a rate of 2 °C/min and calcined at different temperatures of 120 °C (film A), 400 °C (film B) and 500 °C (film C) for 1 h in an air atmosphere
Effect of carbon nanotubes’ crystal structure on adsorption kinetics of small molecules
An experimental study utilizing ultra-high vacuum thermal analysis techniques
[ 13 ], which triggered my interest in this topic. In the meanwhile, we performed similar surface chemistry experiments on inorganic nanotubes (NT) such as TiO 2 NTs [ 14 – 16 ] and WS 2 NTs [ 17 ] together with the materials science and synthetic
respect to CO and O 2 both in the absence and presence of H 2 [ 2 , 6 – 14 ]. One of the earliest kinetic studies was conducted by Haruta and co-workers on TiO 2 , α-Fe 2 O 3 , and Co 3 O 4 supported Au catalysts [ 6 ]. In the temperature range studied
]. Previously, it was shown that a significant intensification of oxidative delignification of wood by hydrogen peroxide in acetic acid–water medium at 120–130 °C takes place in the presence of sulfuric acid catalyst or suspended TiO 2 [ 3 , 4 ]. Under these
