Active and durable electrocatalysts for methanol oxidation reaction are of critical importance to the commercial viability of direct methanol fuel cell technology. Unfortunately, current methanol oxidation electrocatalysts fall far short of expectations and suffer from rapid activity degradation. Here we report platinum-nickel hydroxide-graphene ternary hybrids as a possible solution to this lo...

This work focuses on the comparison of degradation and mineralization clopyralid with electrochemically produced hydrogen peroxide (electro-H2O2), ozone (electro-ozonation) their mixture (electro-peroxone) points out important differences among performance oxidation technologies. Co-existence decreases concentration increases in bulk, because formation recombination hydroxyl radicals. Oxidation...

In this paper we highlight the important contribution made by Bob Madix to the understanding of catalysis at single crystal surfaces, focusing here on a favourite model system of his, namely the oxidation of methanol on Cu(110). Madix showed clearly that the methoxy was the pivotal intermediate involved, and it is bound to the surface through the oxygen atom. Here we demonstrate the nature of t...

Article can be accessed online on: www.ijpsr.com ABSTRACT: Plants rich in antioxidants and phytochemicals especially phenolic groups play a protective role in health and disease conditions, like cancer, diabetes, heart disease hypertension etc. by counteracting reactive oxygen species and inhibiting the lipid oxidation. Morus indica is non-toxic natural therapeutic plant used as herbal medicine...

Using density functional theory (DFT) calculations, we performed a thorough theoretical investigation on the catalytic mechanism of oxidative self-coupling of methanol with molecular oxygen on Au-Ag catalysts. It is found that molecular oxygen can be activated via a hydroperoxyl (OOH) intermediate by taking a hydrogen atom from co-adsorbed methanol with an energy barrier of 0.51 eV, which is ac...

We report the effect of electrochemical oxidation in nitric acid on the electronic properties of epitaxial graphene (EG) grown on silicon carbide substrates; we demonstrate the availability of an additional reaction channel in EG, which is not present in graphite but which facilitates the introduction of the reaction medium into the graphene galleries during electro-oxidation. The device perfor...

Steam reforming integrated with oxidation of methanol was considered with numerical simulation. The parallel micro-channels with circular cross sections were used. Because when the catalytic deposited inside the rectangular micro-channels, it fills up the edges. Hence, the approximation of a cylindrical channel is appropriate. Effect of this changing in cross section was considered and results ...
