Nitrogen doped graphene-supported trimetallic CuNiRu nanoparticles catalyst for catalytic dehydrogenation of cyclohexanol to cyclohexanone
2019, Journal of King Saud University - ScienceCitation Excerpt :Therefore, the metallic copper active sites are not selective. As indicated from the NH3-TPD results, for this particular reaction, the CuNiRu/N-rGO is more suitable as within the actual dehydrogenation of the cyclohexanol to the cyclohexanone prefers the lower acidity active sites (Chang and Abu Saleque, 1993). The stability of the Cu/N-rGO and CuNiRu/N-rGO catalysts was evaluated based on the times on stream (TOS) ∼8 h (530 min).
Dehydrogenation of cyclohexanol over Cu/Al<inf>2</inf>O<inf>3</inf> catalysts prepared with different precipitating agents
2013, Applied Catalysis A: GeneralCitation Excerpt :At low temperature, catalytic performance of copper-based catalysts primarily depends on the presence of metallic copper and monovalent active sites [17]; the acid-base nature of catalyst [5]; and the size, population and dispersion of the Cu species [1]. The activity and stability of the Cu containing catalyst mostly depend on the preparation method and the parameters employed in the particular method [7]. Several methods such as, chemisorption hydrolysis [5], precipitation [7,8,11,17,18], ion exchange [12], impregnation [12–14], electroless plating [6], sol–gel [25], etc. were reported for preparation of copper-based catalysts.
