A filter component includes a catalyst surrounded by a thermally insulative carbon fiber composite. The catalyst can catalyze the chemical reaction of selected gaseous constituents of a gas stream. During catalysis, the catalyst can reach high temperatures. The carbon fiber composite can contain heat generated during the catalysis within the filter component and thereby reduce heat transfer to the surroundings. The filter component can be used in smoking articles. Methods of making and using the filter-component and methods for treating mainstream tobacco smoke are also provided.
