Among the various methane activation reactions, oleum-mediated (SO3–H2SO4) oxidation to methyl bisulfate (MBS), a methanol precursor, is one of best methods in terms conversion and product selectivity. In this report, we investigated effect catalyst concentration on MBS yield using systems (bpym)PtCl2, K2PtCl4, (DMSO)2PtCl2 at 180 °C for 3 h. (bpym)PtCl2 showed very high stability as well over 84%, but its catalytic activity expressed turnovers h was range 50–500. K2PtCl4 17 000 low...
The heterogeneous Fenton-like catalysts based on CuFe2O4 were prepared by polymeric precursor method at several annealing temperatures. obtained respectively characterized X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, point of zero charge measurement, and vibrating sample magnetometer. catalytic activity was evaluated via the oxidation methylene blue with H2O2. results show that phase content particle size increase temperatures whereas surface OH...
A subclass of Metal-Organic Frameworks, Zeolitic Imidazole Frameworks-8 (ZIF-8) is known as an emerging material that has the characteristic a large surface area, good thermal stability well high porosity. Instead having extraordinary properties, ZIF-8 consists Lewis acid and base site on its Zn metals 2-methylimidazole which are important components for catalyst. In this study, Pd-Poly(N-vinyl-2-pyrrolidone) coated (Pd-PVP@ZIF-8) was synthesized by mixed Pd-PVP solution precursors at room...
Abstract The direct oxidation of methane to methanol has been spotlighted research for decades, but never commercialized. This study introduces cost-effective process co-producing and sulfuric acid through a methane. In the initial phase, forms methyl bisulfate (CH 3 OSO H), then transformed into trifluoroacetate (CF CO 2 CH ) via esterification, hydrolyzed methanol. approach eliminates need energy-intensive separation from by replacing former with trifluoroacetate. Through superstructure...
In ongoing attempts to efficiently utilize abundant natural gas, there has been steady scientific and industrial interest in using an environmentally benign inexpensive oxidant (dioxygen O2) for the direct catalytic oxidation of methane oxygenate products under mild conditions. Here, we report homogeneous bis(tetramethylammonium) tetrachlorocobaltate ([Me4N]2CoCl4)-catalyzed methyl trifluoroacetate (MeTFA) with dioxygen O2 trifluoroacetic acid (HTFA) media. [Me4N]2CoCl4 had highest activity...
Due to the increasing demand for propylene, highly selective propylene production from ethylene using small pore zeolite has received significant attention. However, rapid catalyst deactivation due coke deposition on impedes effective in industry. Therefore, it is essential develop a low-temperature regeneration ethylene-to-propylene (ETP) with stable catalytic activity. To achieve such catalyst, various hydrocracking metal species and phosphorus-supported SSZ-13 were prepared evaluated...
