Title (EN) THREE-WAY CATALYST COMPRISING PD-RH ALLOY
(FR) CATALYSEUR TROIS VOIES COMPRENANT UN ALLIAGE PD-RH
(KO) Pd-Rh 합금을 포함하는 삼원촉매
Abstract:
(EN) The present invention relates to a method for preparing a supported catalyst comprising a crystalline Pd-Rh alloy, the method comprising the steps of: (i) producing an impregnated support by means of mixing an inorganic support, a Pd precursor solution and an Rh precursor solution; and (ii) thermally treating the impregnated support in a reducing gas atmosphere.
(FR) L'invention concerne un procédé de préparation d'un catalyseur supporté comprenant un alliage Pd-Rh cristallin. Le procédé consiste: i) à produire un support imprégné par mélange d'un support inorganique, d'un précurseur de Pd en solution et d'un précurseur de Rh en solution; et ii) à soumettre à un traitement thermique le support imprégné dans une atmosphère de gaz réducteur.
(KO) 본 발명은 결정성 Pd-Rh 합금을 포함하는 지지된 (supported) 촉매 제조방법으로서, (i) 무기 지지체, Pd 전구체 용액, 및 Rh 전구체 용액을 혼합하여 함침 지지체를 생성하는 단계 (ii) 상기 함침 지지체를 환원가스 분위기에서 열처리 (thermal treatment)하는 단계를 포함하는, 결정성 Pd-Rh 합금을 포함하는 지지된 촉매 제조방법에 관한 것이다.
