New Paper: 'Titanium(IV)-induced cristobalite formation in titanosilicates and its potential impact on catalysis'

12 September 2018

This new paper describes unexpected phase transitions that occur during the synthesis of titanosilicates, and their impact on catalysis. The formation of cristobalite, which is a crystalline silica phase, appeared to be induced by the presence of Ti4+, during calcination at 750 ⁰C, without the addition of alkali metals, which were previously unknown conditions. The cristobalite thus formed caused the breakdown of the pore network of the titanosilicate catalysts, leading to poor catalytic activity.

This study gives insight into the importance of carefully controlling the synthesis conditions of titanosilicates, to allow greater quality control of the final product.

The new paper titled, 'Titanium(IV)-induced cristobalite formation in titanosilicates and its potential impact on catalysis', has been published in the Journal of Materials Science.
