The kinetics indicate that the rate of the reoxidation of the catalyst mainly determines the activity of the catalyst for the selective oxidation of hydrogen sulfide. The resulting low surface coverage of active oxygen leads to a high selectivity to sulfur, because the low coverage strongly impedes...
There is interest studying the kinetics of hydrogen-hydrocarbons mixtures since the combustion of hydrogen-enriched fuels under fuel-lean conditions in gas turbines could help reducing the emissions of CO, CO 2 and NOx. New experimental results were obtained for the kinetic of oxidation of hydrogen...
The oxidation number of hydrogen is + 1 and of oxygen is - 2 . 氢的氧化值是+1,氧的氧化值是 -2. 来自互联网 2. Three steps are total number of rising and dropping oxidation number to balance equation. 配平氧化还原反应方程式的原则是:还原剂氧化数升高的数值等于氧化剂氧化数降低的数值. 来自...
This chapter describes the mechanism of hydrogen oxidation reaction (HOR) and mentions the complete details. At least in inorganic media, HOR is carried out via combining the following basic processes: dihydrogen dissociative adsorption, transfer an electron from dihydrogen to catalyst, and release the...
the electronic interaction between the Ni nanoparticles and the support leads to balanced hydrogen and hydroxide binding energies, which are the likely origin of the catalyst’s high activity. PGM-free HEMFCs employing this Ni-based HOR catalyst give a peak power density of 488 mW cm–2, ...

We report anabinitiostudy of hydrogen atom migration in methylenebis(oxy)H2CO2(3B2) to form triplet formic acid HCOOH (3A1). From HF, MCHF, and CI calculated energy barriers, we estimate the activation energy to be no less than 30 kcal/mol. We conclude that the hydrogen migration channel...

To date, the effect of oxidation state on activity remains controversial in whether higher or lower oxidation states benefit the enhancement of catalytic activity. Herein, we discover a volcanic relationship between oxidation state and hydrogen evolution
