水热合成的TiAlPOS、TAPO-5、TAPO-11和TAPO-36在稀过氧化氢存在下具有环己烷氧化官能化、环己醇和2-己醇氧化、辛烯-1和环己烯环氧化活性。TAPO催化氧化活性与骨架中的钛原子有关，而与反应液中的钛物种无关。该催化剂的活性和H2 O2选择性顺序为TAPO-5>；TAPO-11>；TAPO-36，TAPO-5的活性和选择性仅略低于钛含量相近、比表面积较高的钛硅沸石(TS-1)。
Titanium AlPOs, TAPO-5, TAPO-11, and TAPO-36, which have been synthesized hydrothermally, were found to be active in cyclohexane oxyfunctionalization, cyclohexanol and 2-hexanol oxidation, and octene-1 and cyclohexene epoxidation in the presence of dilute hydrogen peroxide. TAPO catalytic oxidation activity was shown to be associated with framework-incorporated Ti atoms and not with any hypothetical Ti species in reaction solution. This activity and H 2 O 2 selectivity were in the order TAPO-5>TAPO-11>TAPO-36, with TAPO-5 being only slightly less active and selective than a titanium silicalite (TS-1) sample of similar Ti content and higher BET surface area.
