College of Engineering, Bengaluru, 560019, IN Journal Article 2021 01 02 Abstract Conducting polymer/noble metal nanoparticle (CP/NMNP) composites have made a history of sorts since its inception in the field of electrochemical research, which resulted to be an impetus for scientists to indulge and explore the opportunities it can unleash. This review throws light on the synergic effects and the enhancement in the electrocatalytic activity on dispersing noble metal particles on conducting polymers. This review aids the readers to analyse the electrochemical sensing efficiency of CP/NMNP composites, and provides a platform for the researchers to engineer and develop CP/NMNP composite materials for electrochemical sensing. This work also draws the attention of the readers to the application of NMNP (Ag, Au, Pt, Pd, Ir, and Ru) dispersed on CPs [polyaniline (PANI), polypyrrole (PPy) and poly(3,4-ethylenedioxythiophene) (PEDOT)] and their composites with other materials like carbon nanotubes (CNTs), graphene, zeolites, and peptide nanotubes (PNTs) for sensing of various analytes.
