Mesoporous Oxides

ABSTRACTA synthetic method for the design of heterogeneous catalysts incorporating monodisperse platinum nanoparticles into ordered mesoporous oxide frameworks has been developed. Nanoparticles were synthesized in solution in the presence of surface templating polymer and encapsulated into mesoporous oxide matrices. After polymer removal by calcination, ethylene hydrogenation rates were consistent with previously reported results, while superior activity of low coordination atoms in small crystallites during ethane hydrogenolysis was demonstrated. Changes in reaction selectivity with particle size during the hydrogenation/dehydrogenation of cyclohexene were attributed to a hydrogen coverage effect influencing the hydrogenation pathway and the apparent structure sensitivity of the dehydrogenation pathway.

Long Term Adverse Effects

Amoxicillin is one of penicillin antibiotic groups with active β-lactam which the presence in surface water and wastes not only affects water quality but also causes long-term adverse effects on ecosystems and human health due to their resistance to natural biodegradation. The processing of organic waste electrochemically has the advantages of cheap and efficient cost, waste gas that does not contain toxic and hazardous materials. Have been studied the process of amoxicillin electro-oxidation mediated by a cobalt (III) in a cyclic voltammetry study using a platinum, Pt/Co(OH)2 and Pt/Co as working electrodes in acidic medium HNO3 and H2SO4 as supporting electrolytes solution. The voltammogram of Pt, Pt/Co and Pt/Co(OH)2 electrodes showed that higher current was found in medium of HNO3 0.1 M and it can be used to oxidize the amoxicillin wastes, the two anodic and cathodic peaks can be observed at potential of 200-800 mV (vs Ag/AgCl). The presence of cobalt (III) ions in the system caused the decrease of oxidation current, indicated the presence of degradation to amoxicillin.
