AbstractThe novel photoelectrochemical cathodic protection technology is actively researched and developed for alleviating severe corrosion of marine metallic materials. And the corresponding sustained photoelectrochemical cathodic protection in the dark, under the collaboration of the electron storage materials, is also developed and optimized. WO3, as a kind of electron storage material, shows great potential in this area. The WO3/graphene oxide (WO3/GO) nanothorn cluster composites were synthesized via solovthermal method. The nanoscale graphene oxide (GO) sheets, added as templates, result in the formation of WO3 nanothorn clusters in the WO3/GO composite. The hybrid structure of the WO3/GO composite was formed when the GO adding amount is 0.2 wt%, denoted as WO3/GO 0.2. The lattice of WO3 contracted slightly and the crystallinity of WO3 was enhanced. The WO3/GO 0.2 nanothorn cluster composites promote the transfer and storage efficiency of the electrons compared with pure WO3. The high conductivity of the partly reduced GO leads to a faster electron transfer in the WO3/GO composite. The sustained photoelectrochemical cathodic protection performance of the WO3/GO composite under the assistance of TiO2 (i.e., the coupling of WO3/GO 0.2-TiO2) for 304 stainless steel (SS) was promoted. A larger number of photoinduced electrons, generated by TiO2 under white light illumination, can be stored in the WO3/GO composite and be transferred to the coupled 304 SS electrode after shutting off the light.
