Precise Control of Polyaniline Nanohelices with Chirality Continuum and Their Correlation on Catalytic Performance

-camphorsulfonic acid used as a chiral molecule inducer. After Au nanoparticles were loaded on the surface of chiral PANI NHs, the chiral morphology-dependent catalytic performances of PANI-Au NHs are studied in reduction, oxidation, and enantioselective catalytic reactions, showing that the larger the helical twist degree, the higher the catalytic activity and enantioselectivity of PANI-Au NHs.
