PREPARATION OF SOLID CATALYSTS - AN APPRAISAL

Newer methods of preparation of solid catalysts present opportunities for the synthesis of active, selective, stable, and affordable catalytic materials with high specific surface area. These methods include temperature-programmed synthesis of high specific surface area materials, homogeneous deposition-precipitation, redox deposition-precipitation, chemical anchoring, precipitation from organic solvents, syntheses using amorphous metallic alloy precursors, chemical vapor deposition, and surface-redox tailoring of bimetallic catalysts. These techniques lend themselves to tighter control of the important parameters involved in the complex science of solid state chemistry.
