Optothermal conversion mediated by gold nanoparticles was exploited to generate localized Au/TiO2 inverse opal structures in direct opal substrates. The local enhancement of the electromagnetic field made these nanostructures active sites for SERS and contributed to boosting the efficiency of some reactions, such as the photodegradation of methylene blue, under both UV and Vis irradiation.
