Feb 04, 2022 The structural evolution of iron-based catalysts has been investigated more widely in FTS (17–20).By using in situ x-ray diffraction (XRD) and Raman, Paalanen et al.(18, 19) monitored the evolution of α-Fe/FeO x /FeC x phases during FTS, where the addition of Na and S promotes the reduction of Fe 3 O 4 to iron carbides.Wang et al.() found the formation of core …

Feb 18, 2022 TiO 2 nano truncated octahedron (TiO 2-NTO) and TiO 2 nanosheet (TiO 2-NS) were synthesized through hydrothermal treatment.The hydrofluoric acid solution was added to the tetra n-butyl titanate (TBT) solution and agitated for 0.5 h, and the mixture was then transferred to a 50 mL Teflon reactor for hydrothermal treatment for 24 h at 200 o C.. …

Feb 19, 2022 Wang et al. used the SDBD reactor to eliminate the P123 copolymer from SBA-15. The FT-IR spectra of as-synthesis SBA-15, SBA-15-C, and SBA-15-DBD are illustrated in Figure 10(b). Normally, the aliphatic stretching and bending vibrations are observed at wavenumbers between 2950 and 2840 cm –1 and 1500–1350 cm –1, respectively.

space-time yield of a given reactor can be increases by a factor of 2 to 3; ... As an example, by microwave-assisted hydrothermal synthesis, Xu et al. could prepare hydrogen-selective SOD zeolite membranes with a H 2 /n-butane selectivity 1000. 22 Also mixed matrix membranes based on SOD with polyimide 23 or clay 24 are reported.

They synthesized the support material using two different methods, the solid phase reaction method and the hydrothermal method. [7, 96] The temperature at which water and hydroxyl groups were removed during the hydrothermal synthesis was varied between 873 and 1273 K to find out how this affected the surface area and catalytic performance.
