“…Therefore, the design of catalytic systems with high selectivity to the desired product remains a fundamental objective in the study of this type of reaction. In this sense, heterogeneous catalytic hydrogenation is an interesting alternative to conventional methods that use inorganic hydrides (LiAlH 4 or NaBH 4 ), due to the reduction of toxic waste and the possibility of recovering and reusing the catalyst. , The hydrogenation of acetophenone under heterogeneous conditions has been studied with several supported monometallic catalysts based on Pt, ,, Pd, Ru, and Ni. The Cu/SiO 2 showed a very good activity with a selectivity of 100% toward the alcohol 1-phenyl ethanol . Among these systems, supported catalysts based on Ni are the most useful due to their redox properties and their lower cost than those based on noble metals such as Pt, Pd, etc.…”

“…Specifically, a decrease in their hydrogenating capacity is required to achieve an increase in selectivity towards the desired product. The promoters used such as Ni, Cr and Sn, are more electropositive than the noble metal [6, 7, 8, 9]. They produce a double effect: the noble metal gets a negative charge density, Meδ-, and the active sites are diluted, consequently the hydrogenating capacity is decreased.…”

“…Finalmente, por hidrogenación de alguno de los productos anteriores se obtiene 1-ciclohexiletanol (CE), utilizado en la manufactura de ciertos polímeros [192]. La hidrogenación de acetofenona en condiciones heterogéneas se ha estudiado con varios catalizadores soportados monometálicos a base de Pt [193][194][195], Pd [196], Ru [197] y Ni [197][198][199][200][201][202][203][204]. El Cu/SiO 2 mostró una actividad muy buena con una selectividad del 100% hacia el alcohol 1-feniletanol [205].…”

“…NiPt, NiCr y RuCr [192,197,200] Rajashekharam et al [198,206] propuesto, indica mediante modelos teóricos, que el factor limitante la velocidad de reacción proviene del efecto inhibidor causado por el agua adsorbida en la superficie del soporte durante la reacción [206].…”
