Cu/boehmite: A highly active catalyst for hydrogenolysis of glycerol to 1,2-propanediol

Efficient production of propylene in the catalytic conversion of glycerol

“…Hydrogenolysis of glycerol into 1,2-PDO, which is a valuable chemical mainly used for producing polymers, has been intensively reported over various metal catalysts such as Cu [18][19][20][21][22][23][24][25][26], Rh [27,28], Ru [29,30], Ni [31,32], Pt [33,34], and Ag [26,35]. In this reaction, HA is primarily generated in the dehydration of glycerol, and then hydrogenated into 1,2-PDO [15,16].…”

Ni–S-methylisothiourea complexes supported on boehmite nanoparticles and their application in the synthesis of 5-substituted tetrazoles

“…While, boehmite nanoparticles is not air or moisture sensitive, more importance boehmite nanoparticles can be prepared in water at room temperature using available materials such as NaOH and Al(NO 3 ) 3 .9H 2 O [25]. Boehmite nanoparticles have several advantages such as non-toxicity, stability, high specific surface area (>120 m 2 /g), ease of surface modification due to many hydroxyl groups on its surface, inexpensive and easily and readily availability [26][27][28]. The surface of boehmite nanoparticles are covered by many hydroxyl groups, which makes possible the modification of the surface of boehmite nanoparticles with other functional groups to supported catalysts such as metal complexes.…”

Synthesis of 1,2-propanediol through glycerol hydrogenolysis on Cu–Al mixed oxides

“…The reduction in the presence of H 2 /N 2 made the catalysts active towards the conversion of glycerol due to their acidic properties attributable to the CuCr 2 O 4 cubic spinel phase. Wu et al [17] synthesized a Cu/boehmite catalyst highly active in the conversion of glycerol into 1,2-propanediol. The catalyst was acidic in nature as the presence of Lewis acid sites promoted the glycerol dehydration through acetol intermediate.…”
