Non-covalent functionalisation of amorphous carbon from d-glucose as a novel catalyst for renewable fuels

Jidon Janaun, . and Ong Carrie, . and S. M Anisuzzaman, . and Duduku Krishnaiah, . Non-covalent functionalisation of amorphous carbon from d-glucose as a novel catalyst for renewable fuels. pp. 6-13. ISSN 2289-1692

In this paper a renewable carbon catalyst was developed based on the non-functionalisation method. Three different pyrolysis temperatures at 400C (SC400) 500C (SC500) and 600C (SC600) were used to prepare amorphous carbon. The non-covalent functionalisation was carried out by 1-pyrenesulfonic acid (1-PSA) in organic solvents such as ethanol heptane and dimethylformamide (DMF) and characterised by total acidity TGA FT-IR SEM-EDX particle size BET Porosity and XRD. The total acidity was found to be 1.58 mmol/g for catalyst SC400. The functional groups “COOH “OH “SO‚H and - stacking were detected. The amorphous carbon was stable until 500C. The sulphur content was found to be 0.013mmol/g for SC400. This research approach focused on the direct interaction of carbonaceous support with pyrene moieties and terminal groups (“SO‚H) acting as catalytic acid sites that open a new way to be explored for performing liquid-phase heterogeneous acid-catalysed reactions.

Abstract

In this paper a renewable carbon catalyst was developed based on the non-functionalisation method. Three different pyrolysis temperatures at 400C (SC400) 500C (SC500) and 600C (SC600) were used to prepare amorphous carbon. The non-covalent functionalisation was carried out by 1-pyrenesulfonic acid (1-PSA) in organic solvents such as ethanol heptane and dimethylformamide (DMF) and characterised by total acidity TGA FT-IR SEM-EDX particle size BET Porosity and XRD. The total acidity was found to be 1.58 mmol/g for catalyst SC400. The functional groups “COOH “OH “SO‚H and - stacking were detected. The amorphous carbon was stable until 500C. The sulphur content was found to be 0.013mmol/g for SC400. This research approach focused on the direct interaction of carbonaceous support with pyrene moieties and terminal groups (“SO‚H) acting as catalytic acid sites that open a new way to be explored for performing liquid-phase heterogeneous acid-catalysed reactions.
