From: Cooperative catalysis by a single-atom enzyme-metal complex

a Synthesis of Pd-anchored enzyme. b Pd K-edge EXAFS in R space for Pd1/CALB-P. PdO, PdCl2, and Pd foil were used as references. c Magnified AC-STEM image of Pd1/CALB-P in which the bright dots represent Pd single atoms. d AC-STEM image of Pd1/CALB-P and the corresponding elemental mapping for Pd, C, and O. Scale bars: 50 nm.
