The extensive demand for cleaner environment is forcing the chemical industry to use less hazardous materials. In this regard, solid catalysts have lately attracted the attention of scientists and researchers around the world.1–8 By using sufficient amounts of these heterogeneous catalysts, their catalytic activity for ester formation can be equivalent to that of conventional homogeneous cataly...

Purpose A one-day conference organised by the University of Essex and Consortium Therapeutic Communities, 10 December, 2021 with theme, “The Unconscious Organisations”. Presentations discussions throughout had aim generating ideas sharing knowledge about unconscious how this can inform practitioners working in therapeutic communities other organisations meeting challenge emotional distress. Des...

In order to estimate the Arrhenius and Langmuir parameters of the selective oxidation of methyl (Yn-glucoside on a platinum catalyst, the temperature was varied from 293 to 333 K. The initial reaction kinetics can be described adequately over this temperature range by a Langmuir-Hinshelwood rate equation which is based on two parallel reaction paths: one involving adsorbed methyl cr-D-glucoside...

The influence of operation temperature, inlet gas composition, current density and the anode thickness on methane steam reforming reaction over nickel yttria-stabilized zirconia anodes was experimentally studied in solid oxide fuel cells. experimental results were analyzed using data fitting Power-Law Langmuir–Hinshelwood kinetic models. Similar trends dependence partial pressures observed both...

Kinetic studies of vinyl acetate (VA) synthesis were carried out for Pd (1.0 wt%)/SiO2 and Pd (1.0 wt%)–Au (0.5 wt%)/SiO2 catalysts, with highly dispersed metal particles (Pd and Pd–Au) characterized by X-ray diffraction and transmission electron microscopy–energy dispersive spectroscopy (TEM-EDS). The kinetics of the related CO oxidation reaction were also explored. The kinetics of VA synthesi...

In this work, M-doped TiO2 nanostructures (M: Fe, Co and Ni) were synthesized by reverse microemulsion method. The as-prepared products were analyzed by different techniques such as scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FT-IR). The effect of various dopants (Fe, Co and Ni) on ba...

Abstract These days, textile industries pose a more significant threat to surface water and groundwater sources directly or indirectly by discharging wastewater containing various dyes organic pollutants these sources. The phase-junction-engineered heterogeneous photocatalysis carried out visible light-driven semiconductor photocatalysts is opening new window for the degradation of environmenta...

Abstract Zn-doped NaA molecular sieves were prepared by hydrothermal method using zinc nitrate, sodium metaaluminate, silica sol, etc. as raw materials. The samples characterized XRD, SEM, FT-IR, etc., 300W xenon lamp the light source. Rhodamine B (RhB) was used target degradant for photocatalytic experiments its activity. results showed that ion doping increased number of active sites on sieve...

Abstract The interaction of water with cesium on the strontium titanate surface SrTiO 3 (100), was studied, mainly by means work function measurements and thermal desorption spectroscopy. catalytic role respect to dissociation investigated, applying two different adsorption processes at room temperature (RT): (1) covered (sequential adsorption), (2) co-adsorption process (simultaneous adsorptio...
