The mesoporous anatase TiO2 microspheres were synthesized by a template-free, one-step fast solvothermal process.
The mesoporous anatase TiO2 microspheres with interconnected nanoparticles have the advantages of large surface area and connected-structure for electron transfer.
The mesoporous anatase TiO2 microspheres were further utilized as efficient photoelectrodes for dye-sensitized solar cells.
