Reaction of polycrystalline B4C with energetic O2+ was investigated mainly using Rutherford backscattering spectroscopy (RBS). For 5 keV O2+ irradiation, all of the irradiated oxygen was retained up to the fluence of 2 × 1017 O/cm2 in a temperature range from RT to 600°C. The areal ...
Abstract The cross section of the ion molecule reaction H 2 O + + H 2 → H 3 + + OH and its deuterium counterpart was studied over an energy range 2–100 eV using a tandem mass spectrometer. The measurements permitted a determination of the proton affinity of H2 of 4.37± 0.05 ...
the effects of these gases on the formation of NO and NO2 in the photolysis, the rate constants for the reactions of hydroxyl radicals with these added gases have been determined relative to the reaction OH + HONO = H2O + NO2... RA Cox,RG Derwent,PM Holt - 《Journal of the Chemical...
Energy partitioning in the reaction 2H2+ O2→ 2H2O on Pd(111) We have studied the reaction on Pd(111) at temperatures between 500 and 700 K in the regime of low oxygen coverages ( 2. D2 is dosed using a ... Arne de Meijere,Kurt W. Kolasinski,Eckart Hasselbrink - 《Faraday ...

O2, H2 and H2O have been adsorbed in the dark and the decrease on the concentration of the Ti3+ species has been monitored as a function of the gas exposures. Subsequent band gap illumination partially restores the Ti3+ initial concentration in the cases of O2 and H2 exposures but not in ...
The reaction: was investigated in a quasistatic flash photolysis system at room temperature in the pressure range 0.5 ≦ p /mbar < 1.5 with He as the main carrier gas. The concentrations of CH2(1A1) produced in laser photolysis of CH2CO at λL = 308 nm, and the absolute concentration ...
According to the following reaction, how many liters of hydrogen are required to react with 4.7 L of oxygen at STP? 2H2+O2→2H2O Volume of Reactant: The required volume of a gaseous reactant is determined from the volume of the other ...
The addition of carbonate salts to an aqueous reaction solution has been known to promote stoichiometric O2 evolution and H2O2 production via H2O oxidation. To elucidate the effect of carbonates, density functional theory calculations are performed to study the photoinduced H2O and H2CO3 oxidation ...
