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.

摘要:Disclosed is a flame spray method for the production of nanopowders with controlled mixedness at the submicro-level of individual nanoparticles as well as their use, in particular in heterogeneous catalysis. Said method comprises the steps of i) providing at least two spray nozzles suitable for performing flame spray pyrolysis, each spray nozzle being connected to at least one reservoir, each reservoir comprising a liquid precursor composition, each precursor composition comprising at least one dissolved or finely divided precursor compound, ii) positioning said at least two spray nozzles at an angle and in a distance suitable for getting the desired non-segregated submicron mixture of individual nanoparticles, iii) feeding said at least two liquid precursor compositions to their respective spray nozzle, iv) dispersing, igniting, combusting and mixing said at least two liquid precursor compositions, and v) collecting the nanopowder.
