Two-step preparation of Keggin-PW@UIO-66 composite showing high-activity and long-life conversion of soybean oil into biodiesel
A polyoxometalate acid can be encapsulated into a metal-organic framework to construct a novel kind of solid-acid catalyst. In this work, the two-step method -high-temperature preparation of Zr 6 O 4 (OH) 4 (CH 3 COO) 12 and low-temperature self-assembly-has been adopted to synthesize the PW 12 @UIO...
