Langmuir-Hinshelwood mechanism [12]. In Section 2 we carry out the stability analysis; the algebraic concepts (and the notation) follow the book by Cox et al. [13]. As a real reaction system the wellknown carbon monoxide oxidation is investigated by the same procedure in Section 4. 2. Langmuir-Hinshelwood Mechanism Most surface reactions obey the well-known Langmuir-Hinshelwood (LH) mechanism: ...

Endocrine disruptors in water are contaminants of emerging concern due to the potential risks they pose to the environment and to the aquatic ecosystems. In this study, a solar photocatalytic treatment process in a pilot-scale compound parabolic collector (CPC) was used to remove commercial estradiol formulations (17-β estradiol and nomegestrol acetate) from water. Photolysis alone degraded up ...

To study the role of MgO in reduction N2O circulating fluidized bed boilers, density functional theory was used to evaluate heterogeneous decomposition. The interference SO2 and CO on considered. (100) is a two-step process that includes O transfer surface recovery processes. rate-determining step with barrier energy 1.601 eV, while for Langmuir–Hinshelwood Eley–Rideal mechanisms, energies are ...

In situ broad band sum frequency generation (SFG) spectroscopy was applied to clarify the oxidation mechanism of adsorbed CO on Pt(1 1 1) electrode in alkaline solution comparison with that acidic solution. A single SFG peak due on-top site observed region 1950 – 2150 cm−1. While proceeded a nucleation-growth mode via Langmuir–Hinshelwood (L-H) by reacting OH main 0.1 M HClO4 solution, oxidized...

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...
