What Role Does Catalyst Support Play at High Temperatures?
Catalyst supports are materials that provide a surface for the active catalytic species to disperse and stabilize. At high temperatures, the choice of support becomes even more critical. Supports must be thermally stable to prevent structural changes that could affect the catalyst's performance. Common high-temperature supports include alumina, silica, and zirconia, which offer excellent thermal stability and help to disperse the active species effectively, maintaining high surface areas even under extreme conditions.
