  1. aContents of metal Cu and Pt were determined by ICP–AES
  2. bMean metal particle size of Cu and Pt were determined by TEM
  3. cDispersion of metallic Cu and Pt were measured based on N2O chemisorption and hydrogen oxygen (H2−O2) titration experiments, respectively
  4. dReduction degree of Cu was determined by H2–TPR measurements
