| Abstract [eng] |
One of the most studied methods for producing hydrogen is photoelectrochemical (PEC) water splitting, which uses solar energy and semiconductors that are readily available on Earth [1]. The efficiency of the H2 evolution process under solar light has been greatly enhanced using heterostructure photocatalysts made of semiconductor materials, coupled with plasmonic noble metal nanoparticles (NPs). This is enabled through the excitations of the conduction band electrons at the metal-dielectric interface. Light may be focused and “folded” onto a thin semiconductor film utilizing fabricated heterojunction structures, enhancing absorption characteristics by generating surface plasmon polaritons (SPPs) propagating at the metal/semiconductor interface as well as localized surface plasmons (LSPs) produced in noble metal nanoparticles [2]. This work investigates the effects of characteristic LSPs in quasi-random distributions of plasmonic metal nanoparticles on the visible light absorption and photocatalytic efficiencies of semiconducting TiO2 as a vital comparative prerequisite for the utilization of plasmonic NPs organized into ultrathin periodic arrays with photonic spacings, able to support surface lattice resonances (SLRs), that show orders of magnitude stronger localized electromagnetic fields [3].
