Title (EN) GAS SENSOR AND METHOD FOR PRODUCING SAME
(FR) CAPTEUR DE GAZ ET PROCÉDÉ DE FABRICATION ASSOCIÉ
(JA) ガスセンサ及びその製造方法
Abstract:
(EN) Provided is a gas sensor that includes a filter comprising: an organic sulfonic acid compound containing a sulfo group (-SO3H); a transition metal element; a Lewis acid that contains at least a metallic element from among an Al element, Ga element, In element, Ge element and Sn element; and a porous inorganic carrier that supports the organic sulfonic acid compound and the Lewis acid. Low concentration siloxanes are adsorbed by the Lewis acid supported on the inorganic carrier. Adsorbed siloxanes are polymerized in the filter by means of the sulfo group-containing organic sulfonic acid compound so as not to be detached from the filter.
(FR) L'invention concerne un capteur de gaz qui comprend un filtre comprenant : un composé d'acide sulfonique organique contenant un groupe sulfo (-SO3H) ; un élément métallique de transition ; un acide de Lewis qui contient au moins un élément métallique parmi l'élément Al, l'élément Ga, l'élément In, l'élément Ge et l'élément Sn ; et un support inorganique poreux qui porte le composé d'acide sulfonique organique et l'acide de Lewis. Les siloxanes à faible concentration sont adsorbés par l'acide de Lewis porté sur le support inorganique. Les siloxanes adsorbés sont polymérisés dans le filtre au moyen du composé d'acide sulfonique organique contenant un groupe sulfo de façon à ne pas être détaché du filtre.
(JA) ガスセンサのフィルタは、スルホ基(-SO3H)を含有する有機スルホン酸化合物と、遷移金属元素と,Al元素,Ga元素,In元素,Ge元素及びSn元素の少なくとも一員の金属元素を含むルイス酸と、有機スルホン酸化合物及びルイス酸を担持する無機多孔質担体、とを備えている。無機担体に担持したルイス酸により、低濃度のシロキサンを吸着する。スルホ基を有する有機スルホン酸化合物により、吸着したシロキサンをフィルタ内で重合させ、フィルタから脱離させないようにする。
