It was found that the catalyst calcined at 500 degrees C exhibited the highest catalytic activity, with a HCFC-1233xf conversion of 63.3% and selectivies to HFC-1234yf and HFC-245eb (1,1,1,2,3-pentafluoropropane) of 59 and 38%, respectively, at a reaction temperature of 320 degrees ...
A series of Cr2O3-ZrO2 mixed oxides were prepared by a hydrothermal method and studied in relation to their performance in the dehydrogenation of propane to propylene with CO2. The material prepared from a hydrothermal treatment at 180 degrees C gives an initial propane conversion of 53.3%, whi...

The enormously and rapidly increasing demand of renewable energy storage and conversion technologies promote to develop next generation catalysts for energy device applications [1], [2]. Apart from lithium-ion batteries, fuel cells are considered as one type of the most advanced and eco-friendly ene...
Here, we attempted to investigate the Cr(VI) dominant region eventually to avoid it in the Al2O3–CaO–Cr2O3 system under air atmosphere using powder X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and leaching tests. However, the prime endeavor is to synthesize the new...
