Composite materials based on [PV_xW_12-xO₄₀]^(3+x)− with x = 1 or 2 (PVW and PV2W respectively), included in poly(acrylic acid-co-acrylamide) gel (PAACA), were synthesized. The samples were characterized by different techniques such as FT-IR, ³¹P MAS-NMR, ⁵¹V-NMR, XRD, DTA-TGA, UV–vis DRS, and the acidic properties were estimated by means of potentiometric titration with n-butylamine. Samples containing 10, 20 and 30% (w/w) of polyoxotungstovanadate (POTV) were prepared by inclusion of the POTV in the polymer during its synthesis. According to Fourier transform infra-red and magic angle spinning-nuclear magnetic resonance studies, the predominat anion present in the samples is [PV_xW_12-xO₄₀]^(3+x)−, and there is no evidence of its decomposition during the synthesis of hybrid materials and the drying step. According to XRD results, these anions are greatly dispersed in the PAACA or present as amorphous phases.

UV–vis DRS data reveal that the samples synthesized using POTV with two vanadium atoms (PAACA-PV2W) exhibit lower values of absorption edge energy than those prepared using PVW (PAACA-PVW), which correlates with a higher oxidizing capacity.

The potentiometric titration shows strong acid sites of the hybrid materials, and their number increases with the number of vanadium atoms and with the amount of POTV incorporated in the PAACA grid.

The hybrid materials prepared by inclusion of POTV during the polymer synthesis exhibit appropriate physicochemical features to catalyze the oxidation of diphenyl sulfide (DPS) to its sulfone employing acetonitrile as solvent H₂O₂ as a green oxidant. The samples with 30% w/w of POVT, which show higher catalytic performance, are suitable for the DPS oxidation and can be reused without remarkable drop of their catalytic activity. Furthermore, they show high activity as a catalyst in the oxidation reaction of 4,4´-diamino diphenyl sulfide to the corresponding sulfone (dapsone) used for malaria treatment.

基于[PV _x W _12-x O ₄₀ ] ^{（3 + x）-}且x = 1或2的复合材料（分别为PVW和PV2W）分别包含在聚（丙烯酸-共-丙烯酰胺）凝胶（PAACA）中。合成的。通过不同的技术对样品进行表征，例如FT-IR，³¹ P MAS-NMR，⁵¹ V-NMR，XRD，DTA-TGA，UV-vis DRS，并通过正丁胺电位滴定法评估其酸性。 。通过在合成过程中将POTV包含在聚合物中来制备包含10％，20％和30％（w / w）的聚氧钨酸钒酸盐（POTV）的样品。根据傅立叶变换红外和魔角旋转核磁共振研究，样品中存在的主要阴离子为[PV_x W _12-x O ₄₀ ] ^{（3 + x）-}，并且没有证据表明它在杂化材料的合成和干燥步骤中分解。根据XRD结果，这些阴离子大量分散在PAACA中或以非晶相形式存在。

UV-vis DRS数据显示，使用带有两个钒原子的POTV（PAACA-PV2W）合成的样品比使用PVW（PAACA-PVW）制备的样品具有更低的吸收边能量，这与较高的氧化能力相关。

电位滴定法显示了杂化材料的强酸位，并且其数量随钒原子数以及结合到PAACA栅格中的POTV的数量而增加。

在聚合物合成过程中通过包含POTV制备的杂化材料表现出适当的物理化学特征，以乙腈为溶剂H ₂ O ₂作为绿色氧化剂，可催化二苯硫醚（DPS）氧化为砜。POVT含量为30％w / w的样品表现出较高的催化性能，适用于DPS氧化，可以重复使用而其催化活性不会明显下降。此外，它们在4,4′-二氨基二苯硫醚氧化为用于疟疾治疗的相应砜（氨苯砜）的氧化反应中显示出高催化活性。
