1. The initial activity of pt / tio2 was higher than that of tio2 because it restrained the recombination of electron and hole with supported pt , however the regenerated ability of the pt / tio2 was lower than that of tio2 . after the regeneration , the activity could come back to some 60 % of the original activity and the reaction activity declined rapidly . the reason might be that after regeneration on the surface of pt / tio2 the incomplete oxidation of h2s to produce s was enhanced
   Pt tio _ 2催化劑的初活性比單一的tio _ 2催化劑的初活性高，這是因?yàn)閾?dān)載的貴金屬抑制了電子與空穴的復(fù)合，但其再生性能比tio _ 2差，再生后活性只能恢復(fù)到初活性的約60 ，且反應(yīng)活性迅速降低，這可能由于在再生后的pt tio _ 2表面上， h _ 2s通過(guò)不完全氧化生成s ~ 0的反應(yīng)增強(qiáng)所致。
2. It's difficult to find incomplete oxidation in a sentence. 用incomplete oxidation造句挺難的
