The vacuum condition in the reaction chamber was controlled at 10−3–10−2 torr, and the overpressure threshold for the coating processes was set at 250 torr. Two self-terminating reactions involved in the ALD growth of Al2O3 layer are described as follows: AlOH* + Al(CH3)3 → Al...
). The evolution of the products yields is in accordance with the scheme of the triglycerides (TG) methanolysis reaction consisting of three consecutive steps [4]. In the first step, a molecule of TG is convert1e.d0 into a diglyceride (DG), which then evolves to1.a0 monoglyceride (MG) ...
-Al2O3催化剂上合成草酸二甲酯(DMO)的反应,其催化剂活性与载体的性质及所添加的助剂密切相关.载体的双峰孔分布是影响催化剂活性的关键因素;在双峰孔的基础上,载体的比表面积、孔径及孔体积的增大使催化剂活性升高;助剂的添加可有效地提高Pd的分散度,减小Pd的粒径,从而使CH3ONO转化率从57 1%升高到84 7%,DMO...

(CH3)2S2CuO–MoO3/γ-Al2O3Mars-Van Krevelen modelIn this study, by varying reaction conditions including particle size, space velocity, reactant concentration and reaction temperature, the kinetics of catalytic incineration of (CH3)2S2 catalyzed by the CuOMoO3/-Al2O3 catalyst was investigated....
Rate coefficients for the gas-phase reaction CH3CO + O3?products (1) were measured between 248 and 403 K at 60–200 Torr (N2). Rate coefficients were measured under pseudo-first-order conditions in CH3CO with CH3CO produced by 248 nm pulsed laser photolysis of acetone and monitored using ...
