Extended Data Fig. 7

a, Lower magnification STEM-HAADF image of the Au = Pd/C catalyst. b, c, X-ED spectra obtained from individual nanoparticles, showing a Au-only and a Pd-only nanoparticle. d, STEM-HAADF image and the corresponding X-ED spectrum (inlet) of a Janus-like particle occasionally found in this Au=Pd/C catalyst. e, Activity comparison to the physical mixture f. Reaction conditions: HMF (0.1 M); NaHCO3 (0.4 M); H2O (16 ml); Au/C: 72.1 mg; Pd/C: 71 mg; Au=Pd/C: 143.1 mg; 80 °C; pO2 = 3 bar; reaction time: 30 min. Associated error bars correspond to mean ± s.d. (n = 3).
