## Abstract The transient behaviour caused by the change of the component concentration for CO oxidation on the perovskiteβtype catalyst La~0.4~Sr~0.6~Co~0.4~Mn~0.6~O~3~ was investigated. Results showed that CO was not adsorbed on the catalyst surface and CO oxidation was carried out between the su
The \(\mathrm{Bi}_{1.8} \mathrm{~Pb}_{0.4} \mathrm{Ca}_{2} \mathrm{Sr}_{2} \mathrm{Cu}_{3} \mathrm{O}_{y}\) superconductor is prepared by a citrate precursor method. Nitrate salts of the constituent metals are dissolved in deionized water, and citric acid and ethylene glycol are added. The \(\mathrm
