It is found that the characteristics of the rate of CO_2 formation r versus substrate temperature T are dependent on the ratio P=P_(CO)/P_(O2) in the mixed beam. These characteristics are related to the complicated interactions of co-adsorbed CO and O particles on Pd surface.展开更多

The spectral properties of the metal complexes [Zn(II), Cd(II), Hg(II), Cu(II), Co(II) and Ni(II)] were obtained using the FTIR and UV/Vis spectroscopic techniques. Their antibacterial studies revealed that these complexes as well as the ligands could serve as possible antibacterial agents against pathogens. Melting point and solubility measurements were also carried out. It was observed that these complexes were non-toxic, non-electrolytic and stable solids.展开更多

文摘Here some steady-state experiments on oxidation of CO on Pd were performed on a molecular beam apparatus.

These characteristics are related to the complicated interactions of co-adsorbed CO and O particles on Pd surface.
