Anew Synthetic Polymers Based on Polyaniline for Dual-Functional Applications: Photoelectrochemical Water Splitting and Antibacterial Activities.

Polysulfanilic acid has a low efficiency for the photoelectrochemical (PEC) production of H from water splitting due to high recombination rate of charge and low electrical conductivity. Therefore, polyaniline was doped with polysulfanilic acid to form a copolymer and a blend to enhance its PEC heterogeneous catalytic performance. This was achieved through the improvement of visible light absorption and charge carriers' separation property.
