Extended Data Fig. 5: XPS data.
From: Au–Pd separation enhances bimetallic catalysis of alcohol oxidation
a, b, Au 4f and c, d, Pd 3d /Au 4d regions for Au/C and Pd/C monometallic catalysts before and after a typical HMF oxidation reaction as a physical mixture. Among which, a, fresh Au/C; b, used Au/C; c, fresh Pd/C; and d, used Pd/C. TPR data for the physically mixed Au/C + Pd/C catalyst and the Au@Pd/C catalyst e, before and f, after HMF oxidation.
