Poresupports

Poresupports is a term that can refer to several different concepts, primarily within the context of porous materials and their applications. In a general sense, it describes materials or structures that are designed to hold, enhance, or interact with porous substances. This can manifest in various fields.

Within the realm of filtration and separation, poresupports are often the structural matrix that contains and maintains the porosity of a filter medium. These supports ensure the filter retains its integrity and shape under operational pressure and flow, allowing fluids or gases to pass through while trapping unwanted particles within the pore network. Examples include the ceramic or polymer structures that hold a membrane in place.

In catalysis, poresupports are critical for immobilizing active catalytic species. The porous nature of the support provides a large surface area, which is essential for maximizing contact between reactants and the catalyst. The pore size and distribution of the support can significantly influence the diffusion of reactants and products, thereby affecting the overall catalytic activity and selectivity. Common materials used as poresupports in catalysis include alumina, silica, and zeolites.

The term can also be applied to the physical structures used to create or maintain porosity in a material during its manufacturing process. For instance, in the creation of porous ceramics or metals, sacrificial agents or templates might be used and then removed, effectively acting as temporary poresupports. The overall function of a poresupport is to facilitate or enable the desired porous characteristics of a system.
