The effect of reduction temperature on the the surface composition of Cu/ZnO and Cu/ZnO/SiO2 catalysts was investigated using Low-Energy Ion Scattering. Results showed that the copper and zinc signals can be separated by applying isotopic enrichment and that lead originated from the 68ZnO raw material and segregated to the surface during catalyst reduction. Findings also suggested that the reduction at high-temperature causes the zinc oxide to be segregated to the surface.
