In this study, the W18O49 nanowire bundles were grown on the surface of nanoporous TiO2 sphere by a two-step solvothermal method to fabricate a novel TiO2–W18O49 nanowire bundle (TW) heterojunction structure. The TiO2 core and ethylene glycol play important roles in the synthesis. The prepared TW ph...
