What is it about?
In this work we studied the use of chelatioin-polymerisation based sol-gel synthesis and compared this to a conventional sol-gel method. The Pechini method, as it is commonly known, imparts homogenous cation distribution and promotes the formation of porous open structures alongside the anatase to rutile transformation.

Why is it important?
The effects of doping in semiconductor oxdies depend highly on the synthesis method applied. The study here demonstrates the role of synthesis processes, specifically cation immobilisation (entrapment) in phase formation, morphology and intervalence charge transfer effects.
Perspectives
This study demonstrates the importance of gaining insights into the role of synthesis procedures. Considering the relationships between materials processing and performance need to be better established to facilitate the design of functional materials, with TiO2 photocatalysts being just one example of why this can be important.
