Abstract

AbstractAs 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 Au11/SBA‐15 and Cu13/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.
