Heterogeneous Catalysts

Science, 1980
Proven catalysts exist in many different forms and with many different kinds of composition. An understanding of how catalysts function is beginning to emerge in a few areas, and some superior catalysts have been developed as a result of this knowledge. Applications of new techniques and disciplines should lead to impressive advances in the years ahead.

Aerogel Catalysts

Advances in Science and Technology, 2010
Aerogels are often largely mesoporous solids, with a porosity which may exceed 90 vol% and a specific surface area up to 1000 m2 g-1. Such materials were first obtained by Kistler in 1932, and designate gels in which the liquid was replaced with a gas without collapsing the gel solid network. Contrary to xerogels dried from wet gels by evaporation with

Homogeneous catalysts to solid catalysts

Current Opinion in Solid State and Materials Science, 1996
Abstract Recent advances have been made in the transformation of homogeneous to solid catalysts. They include the use of metal complexes immobilized on organic and inorganic supports, solid acids and bases, redox molecular sieves as solid catalysts for liquid phase oxidations, zeolite-encapsulated metal complexes and supported liquid phase catalysts.
