Abstract
The present disclosure is directed to a catalytic composite that comprises porous supported catalyst particles durably enmeshed in a porous fibrillated polymer membrane. The supported catalyst particles are composed of at least one metal or metal oxide catalyst dispersed on a porous support substrate. In some embodiments, the porous fibrillated polymer membrane is perforated or otherwise contains mechanically formed holes therein. The supported catalyst particles have a large particle population based, at least in part, a d90 value greater than 100 microns. The catalytic membrane composite may be used in filtration applications to remove air polluting substances such as Sox, NOx, dioxin/furan, CO, and others and convert them into non-polluting or less-polluting gas components. Additionally, the catalytic article may be in the form of a filter bag, a honeycomb, a monolith or any other suitable geometrically structured forms.
