The Pt atoms alloyed with Ag promote the decomposition of formaldehyde. The rate equation of methanol oxidation on Ag Pt alloy deduced on the assumption that the surface reaction is the rate-determining step fits the experimental results.doi:10.1016/0021-9517(88)90195-9...
As a 100% atom-economy process, direct oxidation of methane into methanol remains as a grand challenge due to the dilemma between activation of methane and over-oxidation of methanol. Here, we report that water enabled mild oxidation of methane into methanol with >99% selectivity over Au single...
So my delta H is equal to the delta age of my products, minus the delta age of my reactant. Again, we're just using the values given to us right over here. And of course also using this chemical equation to give us the socioeconomic trek ratios. So...
Kinetics of Photoelectrochemical Oxidation of Methanol on Hematite Photoanodes The kinetics of photoelectrochemical (PEC) oxidation of methanol, as a model organic substrate, on α-Fe2O3 photoanodes are studied using photoinduced absorption spectroscopy and transient photocurrent measurements. Methanol is oxid...
The partial oxidation of methane into more useful chemicals such as methanol, ethylene and benzene has been investigated extensively, although yields for these products have been poor 1–4 . Moreover, in several of these processes the re... T Ito,JH Lunsford - 《Nature》 被引量: 716发表: ...
CH4production during incubations with additions of 1 µM acetate, 1 µM methanol, 1 µM dimethylsulfoniopropionate (DMSP), 1 µM methylphosphonate (MPn), 1 µM methanthiol (MeSH), and 1 µM trimethylamine (TMA) at sites P1 (a, near-shore site, water depth 19...
2.1.2 Selective oxidation of methane to methanol Selectively synthesizing methanol from methane during mild conditions is one of the long-standing challenges in chemistry. This is attributed to the high C-H bond strength of methane, its negligible electron affinity, and low polarizability; yet, it...
Thermodynamic calculations The standard free energy change of AOM was calculated from free energies of formation (Stumm and Morgan, 1996). The free energy change for non- standard conditions was calculated using the van t'Hoff equation, concentrations in the medium at the beginning of incubation ...
The direct oxidation of methane to methanol under mild conditions is challenging owing to its inadequate activity and low selectivity. A key objective is improving the selective oxidation of the first carbon-hydrogen bond of methane, while inhibiting the oxidation of the remaining carbon-hydrogen bonds...
The particle size effect observed on the performance of Pt/C electrocatalysts toward the methanol oxidation reaction (MOR) has been investigated with differential electrochemical mass spectrometry (DEMS). The investigation has been conducted under both potentiodynamic and potentiostatic conditions as research...
