摘要: Pd-based catalysts prepared from ultra-pure SiO2 and doped with 5000 ppm Li, Ca La were subjected to CO hydrogenation(H2/CO=2, p=9 bar, T=553 K) in a flow reactor directly attached an ultra-high vacuum chamber facilities for X-ray photoelectron spectroscopy (XPS) secondary ion mass spectrometry (SIMS). The exhibited high selectivity (usually above 99%) methanol synthesis their activities found increase the order Li
