Low conductivity and rapid charge-carrier recombination are the bottleneck issues for semiconductor-based photoelectrochemical sensors. Herein, we report the development of an efficient photoanode consisting of in-situ grown Co 3 O 4 nanostructures decorated with plasmonic gold (Au) nanoparticles (A...
