A kinetic study of oxidation of a potent local anaesthetic chloroprocaine hydrochloride by sodium Nhalo-p-toluenesulfonamides (chloramine-T and bromamine-T) has been carried in HClO4 medium at 303 K. The rate shows a first-order dependence on both [oxidant]o, and [substrate]o, and a fractional-order dependence on acid concentration. Increase in the rate of reaction has been observed with decrea...

Two times higher activity and three times higher stability in methanol oxidation reaction, a 0.12 V negative shift of the CO oxidation peak potential, and a 0.07 V positive shift of the oxygen reaction potential compared to Pt nanoparticles on pristine TiO2 support were achieved by tuning the electronic structure of the titanium oxide support of Pt nanoparticle catalysts. This was accomplished ...

We present here a critical review of several technologically important electrocatalytic systems operating in alkaline electrolytes. These include the oxygen reduction reaction (ORR) occurring on catalysts containing Pt, Pd, Ir, Ru, or Ag, the methanol oxidation reaction (MOR) occurring on Pt-containing catalysts, and the ethanol oxidation reaction (EOR) occurring on Ni-Co-Fe alloy catalysts. Ea...

This paper describes the preparation of Pt- or W-supported Pt nanowires by directly growing them on the surface of Pt or W gauze. The growth direction of the nanowires was determined to be along the <111> axis. Electrochemical measurements were performed to investigate their catalytic performance toward methanol oxidation. It was found from cyclic voltammetry that the Pt nanowires supported on ...

In this work, a review of articles and patents related to the utilization of colloidal metal nanoparticles produced by the decomposition of organometallic precursors as supported electrocatalysts in different electrochemical reactions including hydrogen evolution reaction (HER), oxygen reduction reaction (ORR) and methanol oxidation reaction (MOR) is discussed. In the case of stabilized metal n...

Light-driven chemical reactions on semiconductor surfaces have potential for addressing energy and pollution needs through efficient chemical synthesis; however, little is known about the time evolution of excited states that determine reaction pathways. Here, we study the photo-oxidation of methoxy (CH3O) derived from methanol on the rutile TiO2(110) surface using ab initio simulations to crea...

Methanol oxidation (MOR) and urea (UOR) have been considered for new types of fuel cells, but the lack highly active nonnoble metal catalysts restricts such cells. A NiCo-modified biomass carbon (milk as source)-based catalyst with a 3D structure is synthesized by using salt templates. The results show that 3D-C-NiCo (1:1) exhibits excellent MOR UOR properties potential 1.33 V vs. RHE 1.35 at 1...

The selective oxidation of CH3OH to H2CO over the noble metals Cu, Ag and Au represents one of the oldest industrial catalytic technologies dating back to the 1880s [1,2] and also the first non-Pt based catalytic industrial process. Initially, the catalyst employed for methanol oxidation was metallic Cu and subsequent research three decades later comparing the noble different metal catalysts fo...

Several bacteria are known which are capable of growth with methanol or certain other C, compounds as sole source of carbon and energy (Peel & Quayle, 1961), but little is known about the enzymes involved in the oxidation of methanol (Quayle, 1961). It has been suggested (Dworkin & Foster, 1956; Leadbetter & Foster, 1958; Harrington & Kallio, 1960; Kaneda & Roxburgh, 1959b) that methanol oxidat...

The largest of the gene clusters coding for proteins involved in methanol oxidation is the cluster mxaFJGIR(S)ACKLDEHB. Disruption of most of these genes leads to lack of growth on methanol. The previous results showed that the mutant lacking MxaD grows on methanol although at a low rate. This is explained by the low rate of methanol oxidation by whole cells. The specific activity of methanol d...
