Support Effects on the Activity of Ni Catalysts for the Propane Steam Reforming Reaction.

The catalytic performance of supported Ni catalysts for the propane steam reforming reaction was investigated with respect to the nature of the support. It was found that Ni is much more active when supported on ZrO or YSZ compared to TiO, whereas AlO and CeO-supported catalysts exhibit intermediate performance. The turnover frequency (TOF) of CH conversion increases by more than one order of magnitude in the order Ni/TiO < Ni/CeO < Ni/AlO < Ni/YSZ < Ni/ZrO, accompanied by a parallel increase of the selectivity toward the intermediate methane produced.

Solar light induced photocatalytic removal of sulfamethoxazole from water and wastewater using BiOCl photocatalyst.

The photocatalytic activity of bismuth oxychloride (BiOCl) toward sulfamethoxazole (SMX) elimination was investigated. BiOCl was synthesized according to a simple method using thiourea. Its physicochemical characteristics were determined by nitrogen physisorption, X-Ray diffraction, diffuse reflectance spectroscopy, scanning electron microscopy and transmission electron microscopy.

Persulfate activation by modified red mud for the oxidation of antibiotic sulfamethoxazole in water.

Different pre-conditioning treatments were evaluated in order to stabilize red mud, a waste product from bauxite processing, for obtaining heterogeneous catalysts (named as B1-B3) that can be employed as suitable activators of sodium persulfate (SPS) for the degradation of sulfamethoxazole (SMX), a model antibiotic, in water. The presence of FeO in the composition of the catalysts was found to be a key factor for a suitable activation of SPS, according to the XPS measurements. The oxidation of SMX was successfully fitted to a pseudo-first-order kinetic model (r > 0.

Synthesis and characterization of CoO/BiVO photocatalysts for the degradation of propyl paraben.

Cobalt-promoted bismuth vanadate photocatalysts of variable cobalt content (0-1.0 wt.%) were synthesized and characterized with various techniques including BET, XRD, DRS, XPS and TEM.

Photodegradation of ethyl paraben using simulated solar radiation and AgPO photocatalyst.

In this work, the solar light-induced photocatalytic degradation of ethyl paraben (EP), a representative of the parabens family, was studied using silver orthophosphate, a relatively new photocatalytic material. The catalyst was synthesized by a precipitation method and had a primary crystallite size of ca 70nm, specific surface area of 1.4m/g and a bandgap of 2.
