A method for producing a core-shell hybrid material made of an activated carbon core surrounded by a mesoporous silica sol-gel shell, the method including the formation of a mesoporous silica sol-gel shell around activated carbon particles. Also, the core-shell hybrid material formed by the method, and its use as a filtering material in filtering systems.

Method for producing core-shell hybrid materials

The invention relates to a multifunctional detector for gaseous compounds, or mixtures of gaseous compounds, selected from NHCl, NHCl, NCl, total chlorine, NOx, where x=1 or 2, O, and X, where X=Cl, Br, or I, in a sample, said detector including a first sensor including an iodide and a reactive compound selected from starch, amylose, amylopectin, xyloglucan, xylan, chitosan, glycogen, polyvinyl alcohol, cellulose or a cellulose compound, &#x3b1;-cyclodextrin, theobromine, and polypropylene block polymers and polyethylene oxide block polymers, included in a block of sol-gel material that is absorbent in the UV spectrum but not in the visible spectrum. The invention also relates to the uses of said detector.
