Mesoporous microspheres of anatase TiO2 were synthesized by hydrolysis of titanium butoxide in butanol. The TiO2 micospheres were about 0.5μm in size, composed of primary nanoparticles of about 10nm, and the specific surface area increased by addition of triblock copolymer (Pluronic F127). TiO2 aggregates with irregular shape were formed by hydrothermal treatment. Before and after calcination, the...
It is challenging to utilize TiO 2 -based composites with high specific surface area to improve dye-sensitized solar cells (DSSCs) performance. Herein, we report efficient TiO 2 -SiO 2 core-shell composites for DSSCs by optimizing the microstructure and crystalline structure. Mesoporous TiO 2 -SiO 2 core-shell composites were synthesized by hydrolysis of TiOCl...
