Thermal shrinkage inhibition mechanism of fumed silica based thermal insulating composite

3d Porous Catalysts for Plasma-Catalytic Dry Reforming of Methane: How Does the Pore Size Affect the Plasma-Catalytic Performance?

“…The maxima of the pore size distributions calculated from N2-sorption and mercury intrusion porosimetry of all CuO samples are listed in Table 1. For CuO-10 and CuO-50, the pore size is much smaller than the diameter of the silica spheres used in the synthesis, which might be caused by shrinkage during thermal treatments [57]. In addition, consistent with the conclusions drawn from the SEM images, the pore neck size of CuO-100, CuO-600, CuO-1000, and CuO-2000 measured by mercury intrusion is smaller than the diameter of the silica spheres used in the synthesis.…”
