Selective dehydrogenation of cyclohexanol to cyclohexanone over biomorphic Cu/ZnO catalysts.

ABSTRACT: A high surface area ZnO support (HSA-ZnO) has been fabricated in a unique thermal decomposition process using broken rice grains as a sacrificial template, zinc acetate trihydrate as ZnO precursor. As-prepared ZnO support exhibited a surface area of 145 m²/gm, which is six times higher than the commercial ZnO. Further, copper-supported HSA-ZnO catalysts with different copper loadings (4, 8, 12 and 16 wt%) were prepared by using wet impregnation method and characterized by physicochemical techniques such as X-ray diffraction (XRD), Thermal gravimetric analysis(TGA), BET surface area, CO₂ temperature programmed desorption of (CO₂-TPD), temperature programmed reduction(TPR) and N₂O pulse chemisorption measurements. The catalytic activity of all the
