Sol–gel process immobilization of TEMPO catalysts on multi-walled carbon nanotubes for electrocatalytic alcohol oxidation†

Abstract

Immobilizing catalysts on electrodes remains a crucial step in developing electrosynthetic and photoelectrocatalytic systems. An innovative method for immobilizing 2,2,6,6-tetramethylpiperidine N-oxyl (TEMPO), functionalized by an alkoxysilane group, around multi-walled carbon nanotubes via a sol–gel reaction is described. The system demonstrates impressive electrocatalytic performance of benzyl alcohols in carbonate buffer at pH 9.
