[求助] 文献中 weakly bonded oxygen species 指的什么氧呀?

O 1s spectrum of CeO2 has two peaks at 528.9–530 eV,
assigned to lattice oxygen. Two shoulder peaks at ca. 531.9 and
533.5 eV are observed,which can be attributed to adsorbed oxygen
and weakly bonded oxygen species (active oxygen), and to
surface oxygen by hydroxyl species and adsorbed water species
presser as contaminants at the surface, respectively.

谢谢大家了
