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.
