KNO3 等钾盐在 Zr O2 上分散并经高温分解后所形成的碱的最高碱强度 (H- )可达 2 6.5,属于固体超强碱 ,在 2 73K下的顺丁烯异构化反应中具有高催化活性。当钾离子在 Zr O2 上的表面密度接近 8K+ /nm2 时 ,样品对顺丁烯异构化反应的催化活性达到最大值 KNO3 and other potassium salts dispersed in ZrO2 and pyrolysis after the formation of the alkali base up to a maximum strength (H-) of up to 6.55, belongs to the solid super base, at 2 73K in the isobutylene isomerization reaction With high catalytic activity. When the surface density of potassium ions on Zr O2 is close to 8K + / nm2, the catalytic activity of the sample for the isomerization of maleic is reached to the maximum
