摘要

A novel type of heteropolyacids, CTAB-CsH₃PMo₁₁VO₄₀ (CTA-CsPAV), was developed by a method of emulsion synthesis using cetyltrimethyl ammonium bromide (CTAB) as the structure promoter, which was applied as a catalyst in the oxidation of methacrolein (MAL) to methacrylic acid (MAA) with fixed-bed reactor. The structure and property of CTA-CsPAV were characterized by FT-IR, XRD, nitrogen adsorption-desorption, NH₃-TPD, SEM, XPS, and so on. The structure-performance relationship of CTA-CsPAV was systematically studied, wherein the influence of surface area, acidity, redox property of CTA-CsPAV were focused and discussed. Importantly, the long-term performance of CTA-CsPAV was also investigated.
