dc.description.abstract | A plasmonic LaFeO3-Ag (LFO-Ag) photocathode was synthesised by incorporating Ag
nanoparticles to excite surface plasmon resonances (SPR) for enhanced light harvesting to
drive photoelectrochemical (PEC) hydrogen evolution. The Ag nanoparticles were modelled
using finite difference time domain (FDTD) simulations and the results show an optimal
dimension of 50-80 nm for SPR enhancement. Nanostructured LFO films were prepared by a
novel and inexpensive spray pyrolysis method and the Ag nanoparticles were dispersed
uniformly on to the films by simple spin coating method. The LFO-Ag photocathode
exhibited strong light absorption capability and high current density, twice that than of its
untreated counterpart. This subsequently led to enhanced PEC hydrogen evolution, doubling
the volume of hydrogen generated compared to untreated LFO. The enhancement is ascribed
to the strong SPR effect and the synergy between the Ag nanoparticles and nanostructured
LFO photocathode. | en_GB |
