Phosphotungstic Acid Supported on Magnetic Mesoporous Tantalum Pentoxide Microspheres: Efficient Heterogeneous Catalysts for Acetalization of Benzaldehyde with Ethylene Glycol

In this study, magnetically-recoverable core–shell catalysts with different amount of H 3 PW 12 O 40 loading [Fe 3 O 4 @C@mTa 2 O 5 -NH 2 -PW 12 (w%)] were prepared by the application of phosphotungstic acid supported on amino group functionalized magnetic core–shell mesoporous tantalum pentoxide mi...
