Framework management : A method of preventing the continuous condensation of transition‐metal species in solution by adding triethyl phosphite is proposed. Condensation reactions between titanium species are inhibited by the presence of the phosphite, which results in less‐condensed titania‐based frameworks (see figure). The calcination temperature controls the framework crystallinity and mesoporosity to give anatase nanocrystal films with high photocatalytic performance.
