Selective Oxidation of Glycerol Catalyzed by Rh/Activated Carbon: Importance of Support Surface Chemistry

“…Until now, these products are being produced by expensive and nonenvironmentally safe oxidation processes, or by low productivity microbial fermentation processes [7]. However, the extensive functionalization of this molecule, with similar reactive hydroxyl groups, renders its selective oxidation particularly difficult [8].…”

Selective glycerol oxidation over ordered mesoporous copper aluminum oxide catalysts

“…[37][38][39][40][41] However, there are only few reports on selective oxidation of glycerol in basic media with non-noble metal catalysts, such as with the toxic and carcinogenic cobalt, [42][43][44] layered double hydroxide supported transition metals, [45][46][47] or using hydrogen peroxide instead of molecular oxygen as an oxidizing agent. 48,49 Key factors for the fabrication of efficient supported catalysts are firstly a high dispersion of the active component on the support material; secondly, high surface areas of the support; and thirdly, large porosity to allow efficient diffusion of reactants to the active centers. A particularly intriguing support for Cu based catalysts is γ-Al 2 O 3 , in which Cu cations are atomically dispersed by occupying the tetrahedral and octahedral sites of Al 2 O 3 .…”

Tethering of Dinuclear Complexes to SBA‐15 and Their Application in CO2 Hydrogenation

“…In general, this "heterogenisation" has taken place using differential catalyst solubility approaches, [24][25] as well as through the use of non-covalent, [26][27] or covalent, [27][28][29][30][31][32][33] interactions between the molecular catalyst and the surface of the solid material either following modification of the surface of the solid or the catalytic material or both.…”
