Abstract The oxygen reduction reaction (ORR) is of paramount interest, in the context both alternative energy applications fuel cells and for on‐site hydrogen peroxide (H 2 O ) production environmental remediation applications. Using theoretical experimental methods, mechanism involved ORR studied on nitrogen‐doped graphitic carbon materials. two principal pathways are four‐electron pathway producing water O), or two‐electron leading to formation H . An atomistic step by proposed understand...
Abstract In this work, we report the preparation of TiO 2 nanoparticles with a high surface area, from 120 to 168 m g −1 by hydrothermal-microemulsion route and hydrothermal temperature effect over particle size, porosity, photovoltaic parameter. The samples were characterized Raman, BET, TEM, SEM-FE, I–V curves, EIS. increase correlates pore size. Although when synthesis was 250 °C, area presents an unexpected decrease c.a. 28%. employed as thin-film photo-anodes for dye-sensitized solar...
Photocatalysis is a method widely used in the degradation of organic pollutants environment. The development new materials very important to improve photocatalytic properties and find applications for TiO2 as photocatalyst. In this article we reported synthesis photocatalyst based on doped with Zn2+ ions highly efficient nitrobenzene. results activity experiments showed that more active than un-doped catalyst an efficiency 99% nitrobenzene at 120 min apparent rate constant 35 × 10-3 min-1.
Abstract. Four thin-film composite (TFC) polyamide negatively charged nanofiltration (NF) membranes (NF-PS-1, NF-PS-2, NF-PS-3 and NF-PS-4) were prepared via interfacial polymerization technique which involved the formation of a thin film at polysulfone (PS) microporous substrate between two immiscible liquid phases; an aqueous phase containing piperazine organic trimesoyl chloride (TMC = 0.25, 0.50, 1.00 2.00 wt%). Correlations intrinsic properties these four NF filtration membranes, in...
The effect of the nature catalyst on performance and mechanism hydrogen oxidation reaction (HOR) is discussed for first time in this work. HOR an anodic that takes place anionic exchange membrane fuel cells (AEMFCs) pumps (HPs). Among investigated catalysts, Pt exhibited best HOR. However, cost availability limit usage. Co incorporated as a co-catalyst due to its oxophylic nature. Five different PtCo catalysts with loading values were synthesized order decrease loading. catalytic activities...
In this work nitrobenzene (NB) degradation was studied through an advanced oxidation process (AOP) by using a photochemical reactor and two kinds of oxidizing reagent: potassium persulfate (K 2 S O 8 ) sodium (Na ), to promote generation HO • radicals.It determined the effect different parameters on degradation, such as: wavelength UV lamps, concentration reagent, type reagent number lamps in reactor.By with radiation 254 nm, NB reached almost 100 % meanwhile, irradiating at 350 nm resulted...
