In-Situ Electron Microscopy Studies of Catalyst Deactivation

Monolithic SiC supports with tailored hierarchical porosity for molecularly selective membranes and supported liquid-phase catalysis

“…In the case of the 7 nm particles, the interparticular voids disappeared (see Figure 6), indicating a complete elimination of the particular structure. The mobility temperature of solid metal oxides (when the particles start to move and rearrange) or the Tammann temperature (the minimum temperature at which a solid would undergo a solid-solid interaction) are around half of the bulk melting point in K [42], and explain these effects. At this temperature, i.e.…”
