Abstract
Description
従って、本発明は、金属の堆積前に酸洗浄された担体上に堆積された金、パラジウム又は好ましくは金とパラジウムの粒子を含むH2O2生成用触媒を提供する。好ましくは、粒子は金及びパラジウムの粒子で、ある担体上に、金豊富なコアとパラジウム豊富な殻を有しうる。
反応媒体は都合よくは水/有機溶媒の混合物で、有機溶媒は水混和性である。メタノール、エタノール、イソプロピルアルコール及びアセトンのような溶媒が適切である。ある試験で、アセトン/水の混合物は二金属触媒の活性を増大することが見出されている(以下の表1参照)。しかしながら、異なる溶媒(イソプロピルアルコール、エタノール)を調べても触媒活性の促進は示されなかった。溶媒効果に関する調査は、有機ペルオキシ種生成の可能性があるので相当な注意を払って行われるべきであるが、アセトン及びメタノールの場合、1H NMR及び13C NMRによる研究で、表1に記載のような条件下ではそのような種の生成はないことが明確に示されている。
硝酸洗浄TiO2触媒の使用は、非酸洗浄触媒と比べて、大きな活性の喪失を被ることなく2℃〜40℃の温度で活性が得られている(表1)。
2.5wt%Au−2.5wt%Pd触媒を、適切な担体材料、すなわち炭素(市販されているG60)、シリカ及びTiO2(主にアナターゼ)の含浸によって製造した。PdCl2(Johnson Matthey)及びHAuCl4・3H2O(Johnson Matthey)の水溶液を用いるインシピエントウェットネス法(含浸法の一種、incipient wetness method)を使用した。形成されたペーストを粉砕し、80℃で16時間乾燥させ、静止空気中、典型的には400℃で3時間焼成した。
担体をAuとPdの含浸(実施例1に記載の通り)前に酸処理し(3時間、100ml)、過酸化水素合成を実施例1に記載のようにして測定した。純水中で3時間洗浄した参照サンプルも試験した。以下の結果が得られた。
溶媒及び溶媒/水の組成を変えて、G60酸処理及び水処理担体から形成された触媒について過酸化水素合成を測定した(実施例1のように)。全触媒とも静止空気中400℃で3時間焼成した。結果は次の通りであった。
担体と含浸触媒の各例を過酸化水素分解に関して試験した。全触媒とも静止空気中400℃で3時間焼成した。以下の結果が得られた。
実施例1で詳述した触媒担体をAu及びPdで含浸する前に、硝酸塩(ナトリウム、カリウム及びアンモニウム)で処理し、過酸化水素合成(実施例1に記載の通り)について試験した。全触媒とも静止空気中400℃で3時間焼成した。以下の結果が得られた。
過酸化水素合成を、G60の酸処理及び水処理された炭素上に担持され400℃で3時間空気中で焼成された2.5wt%Au−2.5wt%Pd触媒を用いて実施した。オートクレーブを30分おきにガス抜きし、過酸化水素濃度を測定し、ガス混合物を再充填して合成を続行させた。得られた結果を図4に示す。
過酸化水素合成を、様々な反応温度で、TiO2(酸処理及び水処理されている)上に担持された2.5wt%Au−2.5wt%Pd触媒(その後空気中400℃で3時間焼成)について実施例1のように測定した。以下の結果が得られた。
