Hidrogenación de cinamaldehído sobre catalizadores Au/ZrO2 y Au/ZrO2-SiO2. Efecto del soporte y método de preparación

Abstract: Se prepararon catalizadores de oro soportados en ZrO2 and ZrO2-SiO2por impregnación incipiente (Imp.I.)y depositación-precipitación con urea (DPU) con una carga nominal del metal del 1 %. Los sólidos fueroncaracterizados por difracción de rayos X (DRX), fisisorción de nitrógeno y reducción a temperatura programada(TPR). La actividad catalítica fue evaluada en la hidrogenación de cinamaldehído. La selectividad hacia elproducto deseado es influenciada por la fase cristalina o amorfa del soporte y el método de de… Show more

“…(pyr) 2 Co(CH 2 SiMe 3 ) 2 was used in cobalt‐catalysed homogeneous hydrogenation for C=C, C=O, and C=N bonds [15]. Moreover, ZrO 2 , Al 2 O 3 and SiO 2 were used as supports for hydrogenation of CAL [16, 17]. Platinum and rhodium particles encapsulated in Y‐type zeolite are much more selective for the hydrogenation of CAL to cinnamyl alcohol (COL) than active charcoal‐supported platinum and rhodium catalysts [18].…”

“…suportados deste projeto, além dos sítios metálicos que promovem a hidrogenação do furfural, a presença de sítios ácidos no suporte pode favorecer outras rotas reacionais. (AN et al, 2013;JOUVE et al, 2019;ROJAS et al, 2008) e portanto se configura como a principal contribuição deste trabalho.…”
