“…In another study,S ouza and co-workers studied the impact of metal-metal interactions, as well as the role of acidic supports for NiCu-catalyzed CTH-I of glycerol. [41] They confirmed that bimetallic NiCu/Al 2 O 3 and NiCu/ZSM-5o utperformed monometallic catalysta dmixtures in terms of conversion and selectivity to 1,2-PDO. Specifically,b imetallic catalysts display about 90 %c onversiona t2 50 8Cu nder 4.0 MPa N 2 ,w ithaselectivityt owards 1,2-PDO of 15-25 %a s conversion proceeds.…”

“…Copper is known for its poor hydrogenolytic activity towards C-C bond but it is an efficient catalyst for C-O bond hydrogenation and dehydrogenation reactions. In fact, different publications using Cu as a metallic active phase on different supports (ZrO 2 , Al 2 O 3 , ZSM-5, ZnO, SiO 2 ) have shown 1,2-PDO as a principal product [10][11][12][13][14].…”

“…Although Cu has been used as an active phase on several support with different physicochemical properties [10][11][12][13][14], its use on activated carbon has only been as a promoter of Pt for glycerol oxidation [29]. Therefore, the present work investigates the effect of thermal treatment of activated carbon as supports for copper catalysts for glycerol conversion.…”

“…No obstante, esto, se han utilizado métodos de coprecipitación [66,[181][182][183], deposición-precipitación [184][185][186] e intercambio iónico [174,187]. En el estudio de catalizadores de Cu, se han empleado soportes basados en óxidos tales como γ-Al2O3 [168,171,173,177,180,188,189], SiO2 [66,90,184,190,191], ZnO [50,62,183], TiO2 [177,192], MgO [185] y Cr2O3 [80], zeolitas del tipo Y [182] y HZSM-5 [193], sílices mesoporosas (HSM) [175], SBA-15 [176] e hidrotalcitas [181,193].…”

“…Para los soportes ácidos, como ZnO [50,62,183], Cr2O3 [80], γ-Al2O3 [168,171,173,177,180,188,189], y las zeolitas del tipo Y [182], se ha reportado que los sitios ácidos del soporte favorecen la deshidratación del glicerol a AcOH que luego se hidrogena sobre los sitios metálicos del Cu, aunque la fase activa de Cu también genera la ruptura del enlace C-O.…”
