Thông tin tài liệu:
In this study, SrTiO3 catalyst was prepared by sol-gel method and CuOZnO by co-precipitation for oxidative coupling of methane (OCM). The XRDresults showed a stable phase structure and high crystallinity with both samples. NH3-TPD recorded weak acid centers on SrTiO3, leading to coke formation on the impact surface. H2-TPR and O2 - TPD express the redox of CuO-ZnO, resulting in a deep oxidation product of CO2.
