Vapor phase hydrogenation of levulinic acid using formic acid as a hydrogen source has been conducted over ordered mesoporous $$\hbox {Cu/Fe}_{2}\hbox {O}_{3}$$ Cu/Fe2O3 catalysts prepared by hard template method using mesoporous silica, SBA-15. X-ray diffraction result reveals the absence of copper peaks because of either highly dispersed state, or formation of a solid solution with iron oxides...
A study on the efficient use of hydrogen was made over Cu–MgO–Al2O3 (hydrotalcite like precursor) catalyst prepared via co-precipitation method for the simultaneous synthesis of cyclohexanone and aniline by the coupling of cyclohexanol dehydrogenation and nitrobenzene hydrogenation in vapour phase. Presence of easily reducible CuO species as observed from TPR and higher Cu dispersion with smaller...
