Sulfonated Reduced Graphene Oxide: An Acid Catalyst that Efficiently Promotes the Esterification of Glycerol
نویسندگان
چکیده
A sulfonated graphene catalyst was designed and tested in the acetylation of glycerol. The synthesized using graphite as starting material comprised three stages, which included: (i) synthesis oxide by means a modified Hummers method, (ii) reduction with ascorbic acid, (iii) functionalization sulfanilic acid situ diazotization. Structural, morphological chemical properties were characterized SEM, XRD, FT-IR spectroscopy. acidity determined elemental analysis. catalytic glycerol studied compared commercial sulfonic resin, i.e. Amberlyst® 15. presents attractive features transformation glycerol, allowing for significant increase reaction rate at low temperature, achieving optimum activity greater selectivity towards triacetin.

متن کاملNanospherical like reduced graphene oxide decorated TiO2 nanoparticles: an advanced catalyst for the hydrogen evolution reaction
Modification of titanium dioxide (TiO2) for H2 generation is a grand challenge due to its high chemical inertness, large bandgap, narrow light-response range and rapid recombination of electrons and holes. Herein, we report a simple process to prepare nanospherical like reduced graphene oxide (NS-rGO) decorated TiO2 nanoparticles (NS-rGO/TiO2) as photocatalysts. This modified TiO2 sample exhibi...
