Abstract

The results of temperature-programmed reduction are consistent with those of chemisorption of O2 and H2. In reduced Pt−Pb/Al2O3, a minor part of lead exists as Pbo in an alloy with Pt. The major part of lead is not reduced and exists as carrier-stabilized PbII surface species.

Abstract

Результаты температурно-программированного восстановления согласуются с данными по хемисорбции O2 и H2. В восстановленных Pt−Pb/Al2O3 меньшая часть свинща существует как Pbo в сплаве с Pt. Бϕльшая часть свинща не восстановливается и существует в виде поверхностных соединений PbII, стабилизированных носителем.
