摘要
摘要 研究了 Pd/HZSM-5 和 Pd-nP/HZSM-5 催化剂在乙醇和有酸抑制剂存在的乙醇水溶液中，在温和条件下直接合成 H2O2 并将其分解和加氢的副反应过程中的性质。使用 HRTEM、XRD 和 ICP MS 方法表明，磷修饰导致形成高度分散的 X 射线无定形体系，这是磷在钯中的结构无序固溶体。研究考虑了磷对 H2O2 产率的促进作用的主要因素。研究证实，使用 H 形式的沸石支持物以及磷和酸改性剂可抑制 H2O2 分解的副过程。
Properties of Palladium-Phosphorus Catalysts Supported on HZSM-5 Zeolite in Direct Synthesis of Hydrogen Peroxide
The properties of Pd/HZSM-5 and Pd–nP/HZSM-5 catalysts were studied in direct synthesis and side processes of decomposition and hydrogenation of H2O2 under mild conditions in ethanol and aqueous ethanol in the presence of an acid inhibitor. It was shown, using HRTEM, XRD, and ICP MS methods, that modification with phosphorus led to the formation of highly dispersed X-ray amorphous systems, which are structurally disordered solid solutions of phosphorus in palladium. The main factors governing the promoting effect of phosphorus on the yield of H2O2 are considered. It was established that the use of a zeolite support in the H form, along with the phosphorus and acid modifiers, inhibits the side process of H2O2 decomposition.
