This article critically reviews the applications of solid foam in heterogeneous catalysis and compares its performance with conventional catalysts. The preparation techniques of foam-based catalysts and methods for performance modeling are also discussed. The article identifies the gaps in current research and recommends expanding the use of foam-based catalysts to a wider class of reactions by applying innovative methods. Perspectives on expanding the modeling with solid foam-based catalysts are also presented.
Ceramic and metallic foams have been the subject of research for decades due to their unique and useful properties. The application of foam as a catalytic support is being explored especially for highly endoor exothermic reactions due to better heat transfer. The most widely used catalyst preparation method by wash-coating for foam-based catalysts has several drawbacks. Novel preparation methods are reported in the literature. This article provides a critical review of applications of solid foam in heterogeneous catalysis and performance comparison with conventional catalysts, preparation techniques of foam-based catalysts and methods for performance modeling. The gaps in current research and recommendations to expand the use of foam-based catalysts to a wider class of reactions by applying innovative methods outlined in the literature are identified. Perspectives on expanding the modeling with solid foam-based catalysts are also presented.
