Gold nanoparticles with shape-determined chirality enable the attainment of plasmon-associated optical activities exceeding those exhibited by all previously known natural objects. These nanoparticles, together their subdiffraction light focusing and excitation chiral, plasmon-related near-fields, offer a range very interesting applications. Herein, we propose use these chiral plasmon for asymmetric organic catalysis implementation optically active probes (alkoxyamines). Plasmon triggering causes homolysis C–ON bond in structure employed molecules, forming stable radicals, which can be easily detected using electron paramagnetic resonance spectroscopy. Our investigation delves into influence various parameters on catalytic process, such as not-required circular polarization incident light, activity used.

Abstract Integrating the plasmonic chirality with excellent catalytic activities in hybrid nanostructures provides a promising strategy to realize chiral nanocatalysis toward many chemical reactions. However, controllable synthesis of catalytically active nanoparticles tailored geometries and compositions remains significant challenge. Here it is demonstrated that Au–Pd alloy nanorods tunable optical surfaces can be achieved by seed‐mediated coreduction growth method. Through manipulating inducers, Au selectively transform into two different intrinsically distinct geometric chirality. By further adjusting several key synthetic parameters, chirality, composition, geometry are fine‐tailored. More importantly, exhibit appealing as well polarization‐dependent plasmon‐enhanced nanozyme activity, which has great potential for plasmon‐induced photochemistry.
