UIO66-membranized SAPO-34 Pt catalyst for enhanced carbon dioxide conversion efficiency

The core-shell catalyst Pt/SAPO-34@UIO-66, Haibao-like cluster, was prepared. The Haibao-like cluster was from Zr-based metal-organic framework UIO-66 coating and grows epitaxially on the surface of nano-SAPO-34 clusters and Pt nanoparticles uniformly dispersed on the UIO-66 membrane. The catalyst Pt/SAPO-34@UIO-66 increases carbon monoxide yield compared with catalysts Pt/SAPO-34 and Pt/UIO-66, and the synergy effect of UIO-66 membrane improves carbon monoxide(CO) selectivity. This proves that the modification of SAPO-34 with UIO-66 membrane can enhance the carbon dioxide conversion efficiency. • UIO 66 -membranized core-shell catalyst Pt/SAPO-34@UIO-66 is assembled. • The catalyst Pt/SAPO-34@UIO-66 improves the CO yield. • The synergistic effect of UIO-66 membrane enhances the CO selectivity.
