(532dc) Sulfur-Trioxide Decomposition over ?–SiC Foam Supported CuFe2O4 in the Sulfur-Iodine Cycle
Figure 1 shows (a, b) FESEM, (c, d) TEM, (e) SAED, (f) HR-TEM, (g) Lattice fringes of CuFe2O4/βâSiC Foam. CuFe2O4 particles were well dispersed on the βâSiC Foam as shown in FESEM and TEM images. The concentric rings in the selected area electron diffraction (SAED) pattern showed the nanocrystalline nature of the CuFe2O4/βâSiC Foam. The rings indexed to the planes of tetragonal CuFe2O4 (PDFâ 34-0425). The magnified view of the selected portion of the HRâTEM image showed the lattice fringes of CuFe2O4/βâSiC Foam, the interplanar distance was found to be 0.25 nm corresponded to the (211) plane of tetragonal CuFe2O4. The activity of the catalyst approached equilibrium conversion with increase in temperature. Issues such as low catalytic activity, pressure drop and temperature gradient can be tackled with the synthesized catalyst because foam structure of a support is considered to have high heat transfer due to its interconnected structure and low pressure drop as compared to pellet form in a packed bed reactor.
