catalystsupport
A catalyst support is a material that carries and disperses the active catalytic species in heterogeneous catalysis. The support provides a high surface area, porous structure, and mechanical stability to enhance the accessibility of active sites, improve dispersion, and reduce sintering or leaching of the active phase during reaction conditions. Supports can also influence the catalyst’s electronic properties and acid–base characteristics, affecting activity, selectivity, and durability.
Common supports include oxide materials such as silica (SiO2), alumina (Al2O3), and titania (TiO2), which offer
Preparation and design of catalyst supports involve methods such as impregnation or incipient wetness to load
Applications span broad areas of heterogeneous catalysis, including hydrogenation, oxidation, reforming, hydrodesulfurization, and environmental catalysis, as
Challenges include thermal sintering, metal leaching, coking, and chemical degradation of the support, which can reduce
