Nanomaterials Free Full-Text Titanium Dioxide
Titanium dioxide nanoparticles (TiO2 NPs) have some limitations such as their low surface area high bandgap energy and low recycling ability. To overcome these limitations TiO2 can be prepared in microscale/macroscale structures. TiO2 microscale structures in comparison with TiO2 nanopowder have higher surface areas more tunable pore structures and better top photocatalytic activity. Hollow microspheres of titanium dioxide have been prepared by spray-drying a colloidal suspension of an exfoliated titanate followed by heating above 400 degrees C.
