Abstract:
A series of TUD-1 structures incorporated with Zr⁴⁺ for creating Lewis acidity were prepared by employing tetraethylene glycol (TEG) as a simple organic templating agent. These materials have varying nSi/nZr ratios and are shown to be disordered mesopores with narrow pore size distribution and a specific surface area of 600 m²/g. Three dimensional wormhole like pores with Zr⁴⁺ in tetrahedral coordination was confirmed by HRTEM and diffuse reflectance UV–vis, XPS studies, respectively. The moderate Lewis acidity of ZrTUD-1 is shown to be a promising catalyst for gas phase tert-butylation of phenol.
