Surface tunctionalization of glassy carbon electrodes via adsorption, electrografting and click chemistry using quantum dots and alkynyl substituted phthalocyanines: A brief review

摘要

In this work, glassy carbon electrodes are functionalised with alkynyl substituted phthalocyanines via electrografting and click chemistry as well as with quantum dots (QDs)-phthalocyanine conjugates via adsorption. The use of click chemistry and the addition of QDs is to try observe improvements in the electrocatalytic behaviour of electrocatalyst compared to similar electrocatalysts in literature. The electrografting and click chemistry methods provide greater molecule stability on the substrate surface due to the covalent bonds formed. Results show that these methods of electrode fabrication do improve the functionality of the electrocatalysts.
