Abstract
Graphene oxide-based nanocomposite multilayer films with polyethylene imine (PEI) and H4[SiMo12O40]4- POM interface have been investigated for their electrocatalytic reduction of chloroform in water. Resulting thin films were characterized by both electrochemical and surface based techniques. Cyclic voltammetry was employed to show the layer growth and redox behaviour of the modified electrode system with redox chemistry of the incorporated POM being present. AC impedance gave insights into the porosity and conductivity of the constructed multilayer POM system. Surface characterisation by XPS, AFM and SEM of the modified electrode was also performed to gain insights into the surface morphology and elemental composition of the modified electrode. The constructed multilayer system exhibited an electrocatalytic response to chloroform in water.
