Plasmonic nanostructures loaded onto catalytically inert conductive {support|assistance|help} {materials|supplies|components} arebelieved {to be|to become} advantageous for maximizing photocatalytic effects in photoelectrochemicalsystems {due to|because of|as a result of|on account of|resulting from|as a consequence of} the {increased|elevated|improved|enhanced} efficiency of Schottky barrier-free architectures in collecting hotcharge carriers. {However|Nevertheless|Nonetheless|Even so|On the other hand|Having said that}, the systematic mechanistic investigation and description {of the|from the|in the|on the|with the|of your} inertelectrode {support|assistance|help} contribution to plasmonic electrocatalysis is missing.

Upon illumination, only~({3|three} ± 1)% enhancement in catalytic {current|present|existing} was recorded {on the|around the} AuNP/ITO electrodes incontrast to ~(42 ± {6|six})% enhancement on AuNP/HOPG electrodes.
