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