Functionality modification of SWCNT for improved methanol oxidation reaction
Surface functional groups present on the SWCNT carbon support was modified and its effects on methanol oxidation reaction (MOR) was studied. The surface functionality is tailored using controlled acid and base treatment. Acid treatment leads to the attachment of carboxylic carbon (CC) fragments to SWCNT making it hydrophilic (P3-SWCNT). Base treatment of P3-SWCNT with 0.05 M NaOH reduces the CCs and makes it hydrophobic (P33-SWCNT). Platinum nanoparticle catalyst supported on the P3-SWCNT possesses enhanced MOR than that of Pt supported on P33-SWCNT. The high amount hydroxyl groups present on P3-SWCNT allow the surface coverage of -OH groups on Pt catalyst thereby providing more active sites for MOR.
