Silver deposited titania (Ag/TiO2) nanocomposite thin films were fabricated by the simple sonochemical deposition of Ag on preformed aerosol-assisted chemical vapor deposited TiO2 thin films. The photelectrocatalytic performance of a newly fabricated Ag/TiO2-modified photoelectrode was studied for methanol oxidation under simulated solar AM 1.5G irradiation (100 mW/cm2). The Ag/TiO2-modified ph...

In exploration of low-cost electrocatalysts for direct methanol fuel cells (DMFCs), Pt modified tungsten carbide (WC) materials are found to be great potential candidates for decreasing Pt usage whilst exhibiting satisfactory reactivity. In this work, the mechanisms, onset potentials and activity for electrooxidation of methanol were studied on a series of Pt-modified WC catalysts where the bar...

Nickel modified carbon fibre electrodes were prepared by electrochemical oxidation and partial reduction of a graphite fibre electrode with a slow linear potential sweep in 97% H 2 SO 4 solution followed by impregnation & ionexchange with Ni +2 species. The cyclic voltammetry of the modified electrode in an alkaline medium showed electrocatalytic activity towards methanol oxidation which is con...

ConspectusMethane represents one of the most abundant carbon sources for fuel or chemical production. However, remote geographical locations and high transportation costs result in a substantial proportion being flared at source. The selective oxidation methane to methanol remains grand challenge catalytic chemistry due large energy barrier initial C–H activation prevention overoxidation CO2. I...

The methanol oxidation reaction is studied at the single nanoparticle scale under aqueous alkaline conditions. Upon impacting a potentiostated electrode and after ≤ 1 ms steady-state limited catalytic current induced to occur platinum (nominal diameter 50 nm); magnitude of close that seen for both larger arrays nanoparticles polycrystalline ‘bulk’ material suggesting entity activity preserved i...

Background: Methanol is regarded as a biorenewable platform feedstock because nearly all bioresources can be converted into methanol through syngas. Biological conversion of methanol using synthetic methylotrophs has thus gained worldwide attention. Results: Herein, to endow Escherichia coli with the ability to utilize methanol, an artificial linear methanol assimilation pathway was assembled i...

Alcohol metabolism via alcohol dehydrogenase (ADH) and catalase was studied in perfused rat livers by measuring the oxidation of methanol and butanol, selective substrates for catalase and ADH, respectively. In livers from fasted rats, basal rates of methanol uptake of 15 +/- 1 mumol/g/h were decreased significantly to 8 +/- 2 mumol/g/h by addition of butanol. Concomitantly, pyridine nucleotide...

in the urine, and the kidney must have a considerable power of concentrating formate. The inhibition of the appearance of formate during the administration ofethanol is in accordance with Zatman's (1946) interpretation of the earlier experiments, namely, that a primary oxidation of methanol to formaldehyde through the agency of alcohol dehydrogenase is competitively inhibited by ethanol. More r...
