are incorporated into liquid metal/metal oxide (LM/MO) frameworks
in order to form enhanced photocatalytic systems. The LM/MO frameworks,
both with and without incorporated Ga2O3 nanoparticles,
show photocatalytic activity due to a plasmonic effect where performance
is related to the loading of Ga2O3 nanoparticles.
Optimum photocatalytic efficiency is obtained with 1 wt % incorporation
of Ga2O3 nanoparticles. This can be attributed
to the sub-bandgap states of LM/MO frameworks, contributing to pseudo-ohmic
contacts which reduce the free carrier injection barrier to Ga2O3.
