摘要

摘要 通过离心自蔓延高温合成法制备了高熵合金,并将其用作制备一氧化碳和丙烷深度氧化及二氧化碳加氢催化剂的前驱体。前驱体通过铝浸出和过氧化氢溶液稳定转化为催化剂。制备的铁钴镍铜、铁钴镍铜钼、铁钴镍铜锰和铁钴镍铜铬催化剂通过 XRD、SEM/EDS 和 BET 方法进行了表征,并在 CO 和丙烷深度氧化和 CO2 甲烷化过程中进行了测试。在 400°C 下,铁钴镍铜催化剂的二氧化碳转化率最高,达到 50.6%,甲烷选择性为 77.5%。深氧化过程的最佳催化剂是 FeCoNiCuCr,其 CO 的 100% 转化温度为 250°C,丙烷的 100% 转化温度为 450°C。

Multifunctional Catalysts Based on High-Entropy Transition Metal Alloys

High-entropy alloys were produced by centrifugal self-propagating high-temperature synthesis and used as precursors for preparation of catalysts for CO and propane deep oxidation and CO2 hydrogenation. The precursors were converted into catalysts by aluminum leaching and stabilization with hydrogen peroxide solution. Prepared FeCoNiCu, FeCoNiCuMo, FeCoNiCuMn, and FeCoNiCuCr catalysts were characterized by XRD, SEM/EDS, and BET methods and tested in the processes of deep oxidation of CO and propane and methanation of CO2. The highest CO2 conversion, 50.6%, with methane selectivity of 77.5% was achieved on FeCoNiCu catalyst at 400°C. The best catalyst for the deep oxidation process was shown to be FeCoNiCuCr, on which the temperature of 100% CO conversion was 250°C and 100% conversion of propane was achieved at 450°C.

期刊介绍: International Journal of Self-Propagating High-Temperature Synthesis  is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
