“…In addition, it is considered that the reaction temperature would affect the interaction between MnO x and CeO 2 , which is the key factor determining the catalytic activity of samples . Also, at different hydrothermal treatment times, the size and morphology of samples can change, which leads to alteration of the catalyst activity. , Thus, the catalyst morphology, , crystal structure, and surface oxygen vacancy concentration , can be tuned by changing the preparation method and optimizing the preparation conditions. However, for the Ce-OMS-2 catalyst, the relationship between ozone decomposition and the parameters of the hydrothermal synthesis process is not clear, especially regarding hydrothermal temperature and time.…”

In this study, a series of Ce-OMS-2 catalysts were synthesized by a hydrothermal method, their physicochemical properties and catalytic activity for ozone decomposition were evaluated. The results show that suitable grain size and morphology can be formed as needed by tuning the hydrothermal conditions. In this way, the content of surface oxygen in the catalyst can be increased to enhance the reduction performance of the samples. At the same time, the quantity of low-valent manganese (Mn 2+ and Mn 3+ ) can be increased to raise the oxygen vacancy concentration, and finally improve the O 3 elimination performance of the catalyst. On the basis of this study, we screened out a suitable range of hydrothermal conditions, namely 95−100 °C and 8−24 h, which showed a higher ozone conversion rate than manganese oxide catalysts reported to date. The durability of the preferred catalyst under harsh conditions shows that preferred Ce-OMS-2 catalysts can meet the requirements of engineering applications.

Herein, the physical properties such as crystal phase, morphology, and chemical composition for Cu 2 CoSnS 4 (CCTS) nanoparticles, synthesized by hydrothermal growth at 200 °C, are studied according to the short reaction times from 1 h to 6 h, respectively. The raw data of chemical composition, XPS analysis, and their electrical properties of CCTS nanoparticles prepared at 200 °C for 12 h with different Cu concentrations are presented [1] in the present manuscript. Materials properties of CCTS and their electrical, optical properties were systematically studied, and their correlation between physical properties and materials properties is strongly studied in depth mode.
