标题:在 90 oc 下对金属乙酰丙酮化物和乙酰乙酸乙酯配合物进行蒸汽处理以制备金属氧化物
摘要:蒸汽处理是一种通过在低温(<120 oc)下将金属络合物暴露于水蒸气来合成金属氧化物的技术.虽然锌和铝配合物已通过蒸汽处理转化为纤锌矿 Zno 和假 Alooh,但尚未研究涉及蒸汽处理的金属 β-酮酯配合物的其他合成.在此,我们关注金属乙酰丙酮化物 (Acac) 和乙酰乙酸乙酯 (Etac) 配合物(金属 = Mg,Ca,Ba,Ti,Zr,Fe,Co,Ni 和 Cu)在 90oc 蒸汽处理后的行为.Ti(Acac) 2 (O I Pr) 2,Ti(Etac) 2 (O I Pr) 2,Fe(Acac) 3,Co(Acac) 2,Co(Etac) 2,和 Cu(Etac) 2在空气气氛下的蒸汽处理中转化为结晶金属氧化物.其他金属络合物转化为非晶态金属氧化物,金属氢氧化物,金属碳酸盐或不分解.蒸汽处理的水解机理是通过水攻击金属物种来进行的.形成的反应性羟基迅速与其他分子反应,形成金属氧烷键.

标 题:One-Pot Synthesis of Transition Metal-Promoted Chabazites
发明人：VAN TENDELOO LEEN; SCHUETZE FRANK-WALTER; VERHEYEN ELKE JANE JUNE
权利人:UMICORE AG & CO KG
摘要:The invention provides methods for a one-pot synthesis of molecular sieves of the CHA-type. The method uses molecular and non-molecular sieves as sources of silicon and aluminum. A first OSDA is selected from tetraethylenepentamine (TEPA) and triethy-lenepentamine (TETA). The synthesis mixture comprises a first metal selected from copper, iron and zinc. Optionally, the synthesis mixture may furthermore comprise a second OSDA and/or a second metal selected from manganese, cesium, magnesium, calcium, strontium, barium, yttrium, titanium, zirconium, niobium, iron, zinc, silver, lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutetium and mixtures thereof. The molecular sieves of the CHA-type obtainable by the method can be used as SCR-catalytically active substances for the removal of nitrogen oxides from exhaust gases of combustion engines.

摘要:Described herein are catalyst support materials for use in synthesizing ammonia (NH 3 ) from nitrogen gas (N 2 ) and hydrogen gas (H 2 ) and methods of making the same. The support material may comprise (MgO) x (BaO) y (Al 2 O 3 ) z and/or (MgO) x (SrO) y (Al 2 O 3 ) z , on which an ammonia synthesis catalyst such as ruthenium is dispersed. When the catalyst support material comprises (MgO) x (BaO) y (Al 2 O 3 ) z , x is from about 0.05 to about 0.7, y is from about 0.05 to about 0.6, and z is from about 0.3 to about 0.5. When the catalyst support material comprises (MgO) x (SrO) y (Al 2 O 3 ) z , x is from about 0.4 to about 0.7, y is from about 0.05 to about 0.5, and z is from about 0.05 to about 0.3.
