In this work, homogeneous and heterogeneous oxidation of alcohols by H₂O₂ in the presence of [(n-C₄H₉)₄ N]₅[PW₁₁ZnO₃₉].3H₂O and [PW₁₁ZnO₃₉]⁵⁻ supported on Dowex 22 as catalysts have been investigated. Using water as a green solvent, different alcohols were converted into the corresponding aldehydes and ketones in high to excellent yields. Dowex 22 supported polyoxometalate, PW₁₁Zn@Dowex, was also catalyzed highly robust and selective oxidation of unsaturated alcohols. Leaching and recycling experiments on supported catalyst revealed the excellent stability and reusability of this catalytic system.

Dowex上的锌取代的Keggin型多金属氧酸盐：一种绿色多相催化剂，用于氧化水中的醇

在这项工作中，在[（n -C ₄ H ₉）₄  N] ₅ [PW ₁₁ ZnO ₃₉ ] .3H ₂ O和[PW ₁₁ ZnO ₃₉ ] ⁵存在下，H ₂ O ₂对醇进行均相和非均相氧化。^−研究了负载在Dowex 22上的催化剂。使用水作为绿色溶剂，可以将不同的醇以很高的产率转化为相应的醛和酮。Dowex 22负载的多金属氧酸盐，PW ₁₁Zn @ Dowex也被催化高度稳定和选择性氧化不饱和醇。负载型催化剂的浸出和再循环实验表明，该催化体系具有出色的稳定性和可重复使用性。
