Submicrometre-scale polyaniline colloidal spheres: photopolymerization preparation using fluorescent carbon nitride dots as a photocatalyst

The present communication reports on a novel synthesis of submicrometre-scale polyaniline colloidal spheres (PANICSs) using fluorescent carbon nitride dots (CNDs) as a photocatalyst for the first time. The subsequent treatment of such colloidal spheres with an aqueous AgNO3 solution produces Ag nanoparticles (AgNPs) decorated PANICSs (AgNPs–PANICSs) composites. Such composites exhibit remarkable catalytic performance toward catalytic reduction of 4-nitrophenol and electrochemical reduction of H2O2.
