Abstract

The excitation of the localized surface plasmon leads to the generation of highly localized electric field. Within the field, the huge field gradient can manipulate molecular behavior, resulting in possible modulation of chemical reactions at electrified interfaces with plasmon-active metal nanostructures. In this study, we have observed the effect of the plasmonic excitation on the plasmon-induced hydrogen evolution reactions. Through various photoelectrochemical measurements, the appearance of the unique molecular process has been observed through the examination of the isotopic effect. In addition, the functionalization of the plasmonic electrode using the molecular catalyst has also been examined.
