Abstract: The present disclosure discloses a porous ammonia synthesis catalyst, its preparation method and use, which are suitable for catalyzing ammonia synthesis reaction by using nitrogen and hydrogen as raw materials. The porous ammonia synthesis catalyst is a novel ammonia synthesis catalyst material prepared by taking metal coordination compound as template, uniformly dispersing the metal coordination compound in silica gel through a sol-gel method, then carrying out hydrothermal aging, and finally controlling calcination conditions. Compared with traditional synthetic ammonia catalysts, the porous ammonia synthesis catalyst has uniform pore distribution, easily regulated pore size, large specific surface area, easily regulated aggregation degree of metal active centers, particle size, distribution, structure and composition, high ammonia synthesis catalytic efficiency, ammonia synthesis catalysis under mild reaction conditions, high stability, low catalyst preparation cost, which can completely replace existing ammonia synthesis industrial catalysts.

Abstract: The present invention discloses methods for producing a guest@nanoporous-host materials, and guest@nanoporous-host materials produced according to these methods. Methods according to the invention comprise steps of infiltrating a nanoporous host material with one or more reagents and a target guest precursor in a reaction environment such that a reaction occurs to form the target guest species within the pores of the nanoporous host material. The reagent comprise either a redox reagent and/or a pH modulator. By analysis of appropriate electrochemical potential-pH diagrams and careful selection of suitable reagents and control of process conditions to produce desired target guest particles from selected target guest precursors, the synthesis strategy to form the guests can be more flexible and versatile than known methods, because typically milder reaction conditions can be used than in such known methods.

Abstract: A process of producing a catalyst comprises forming mesoporous beta zeolite particles, impregnating mesoporous beta zeolite particles with a metal and phosphorus to produce a metal and phosphorus impregnated zeolite, and incorporating the metal and phosphorus impregnated zeolite with clay and alumina to produce the catalyst. The forming step comprises converting a crystalline beta zeolite to a non-crystalline material with reduced silica content relative to the crystalline beta zeolite, and crystalizing the non-crystalline material to produce mesoporous beta zeolite particles.
