摘要：

As heterogeneous catalysts, nanoclusters have been extensively investigated because of their exceptional catalytic performance. In this work, we propose an electrostatic attraction strategy to immobilize atomically precise positively charged [Au52Cu72(SR)(55)](+) (denoted as Au52Cu72(SR)(55)) nanoclusters supported onto negatively charged SBA-15. As expected, the Au52Cu72(SR)(55)/SBA-15 catalysts display outstanding activity for driving the benzyl azide-phenylacetylene cycloaddition reaction (called as click reaction). In comparison to Au-11/SBA-15 and Cu-13/SBA-15 catalysts, the bimetallic Au52Cu72(SR)(55)/SBA-15 catalysts exhibit the highest catalytic activity for click reaction. Moreover, to explore the effect of ligands on the catalytic performance of Au52Cu72(SR)(55)/SBA-15 catalysts, Au52Cu72(SR)(55)/SBA-15-X (X is the heat treatment temperature, X=120, 250, 300) catalysts are obtained by calcining at different temperatures. Compared with Au52Cu72(SR)(55)/SBA-15-X (X=120, 250, 300), the uncalcined Au52Cu72(SR)(55)/SBA-15 catalysts show the best recyclability for click reaction. The structural integrity of the Au52Cu72(SR)(55) nanoclusters is a key factor contributing to their exceptional cyclic performance. This work will be valuable for designing an ideal ligand-protected clusters-based catalysts with superior performance for organic reactions.
