Preparation of solid catalysts: an appraisal

Abstract

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, 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.
