Molecular Bottom‐Up Design of Single‐Site Copper‐Palladium Catalysts for Selective Glycerol Electro‐Oxidation

open access: yesAdvanced Energy Materials, EarlyView.
A bimetallic Cu‐Pd single‐site catalyst for the selective and efficient electrooxidation of glycerol to formate and C3‐products (lactate, glycolate, glycerate) is reported. Experimental and theoretical studies shed light on the catalyst function and reveal that Pd sites facilitate the adsorption of hydroxyl (C‐OH) species which prevents C‐C bond ...

Hybridization of Homogeneous and Heterogeneous Catalysis to Develop a Novel Biocatalyst via Immobilization of Lipase on Surface Modified Mesoporous Silica Towards Biodiesel Synthesis Application

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
The 3‐(methacryloyloxy)propyltrimethoxysilane surface functionalized SBA‐15 (MP‐SBA‐15) is used for the first time as a lipase carrier. The immobilized CAL‐B exhibits high thermal stability and superior catalytic activity. CAL‐B/SBA‐15 suggests that optimum hydrophobicity gives better catalytic activity.
