A novel poly(vinyl alcohol) post-precipitation template synthesis and property tuning of photoactive mesoporous nano-TiO2

For the first time, a facile method is introduced to obtain ultrathin, mesoporous TiO2 nanosheets by the alkali precipitation of aqueous TiCl3 in the presence of NH4OH, and in-situ templating with polyvinyl alcohol (PVA). The synthesized titania have been characterized by N2 adsorption-desorption me...
