A novel, mesoporous composite of Mo doped TiO2/reduced graphene oxide is synthesized to be used as a highly efficient heterogeneous acid catalyst. The composite has a high surface area (263 m2 g-1) and a monomodal pore size distribution with an average pore diameter of 3.4 nm. A comprehensive characterization of the synthesized material was done using PXRD, Raman, BET, SEM, EDX, TEM, TGA, and XPS. The composite exhibited excellent catalytic activity (1.6 h-1 TOF, >99% GC yield, and >99% selectivity) towards acetalization of cyclohexanone at room tempertaure within 30 minutes. The catalyst was reusable up to 4 reaction cycles without any significant loss in the activity and the acidic site calculations showed that the reaction is mostly driven by the weak acidic sites on the composite.
Catalytic reductive etherification of ketones with alcohols at ambient hydrogen pressure: A practical, waste-minimized synthesis of dialkyl ethers

A heterogeneous platinum catalyst was found to efficiently mediate the reductive etherification of ketones at ambient hydrogen pressure. In this environmentally benign transformation, water is released as the only by-product, and this is trapped with molecular sieves. The preparative utility of the new reaction protocol is demonstrated by the synthesis of ten unsymmetrical ethers from the corresponding ketones and primary or secondary alcohols.
