Abstract: A nanocrystal-sized cerium-zirconium mixed oxide material includes at least 30% by mass zirconium oxide; between 5% to 55% by mass cerium oxide; and a total of 25% or less by mass of at least one oxide of a rare earth metal selected from the group of lanthanum, neodymium, praseodymium, or yttrium. The nanocrystal-sized cerium-zirconium mixed oxide exhibits hierarchically ordered aggregates having a d50 particle size less than 1.5 μm and a total pore volume after calcination at a temperature of 600° C. or more that is at least 0.7 cm3/g with a fraction of pores between 2 nm to 10 nm being less than 15%. The nanocrystal-sized cerium-zirconium mixed oxide material is prepared using a co-precipitation method followed by milling the dried and calcined oxide material. The nanocrystal-sized cerium-zirconium mixed oxide material forms a particulate filter that may be used in an exhaust system arising from a gas or diesel engine.

Abstract: A method of forming an AEI-type zeolite in a hydrothermal synthesis without the use of hydrogen fluoride (HF) and in the absence of any FAU zeolite Y. A gel composition formed upon using this method includes one or more sources of silica; one or more sources of alumina, one or more organic structure directing agents (OSDA); a source of alkali metal ions; and water. This gel composition is defined by the molar ratios of: SiO2/AI2O3 16:1 to 100:1; M2O/SiO2 0.15:1 to 0.30:1; ROH/SiO2 0.05:1 to 0.20:1; and H2O/SiO2 5:1 to 20:1; wherein M is the alkali metal ion and R is an organic moiety derived from the OSDA. This gel composition, after reacting at a temperature between 135° C. to about 180° C. for 15 hours to 168 hours forms the crystalline AEI-type zeolite having a silica to alumina ratio (SiO2:AI2O3) that is greater than 8:1.

Abstract: A method of forming an SSZ-13 zeolite in a hydrothermal synthesis yields an SSZ-13 zeolite that exhibits a silica to alumina (SiO2:Al2O3) molar ratio (SAR) that is less than 16:1; has a morphology that includes one or more of cubic, spheroidal, or rhombic particles with a crystal size that is in the range of about 0.1 micrometer (μm) to 10 μm. This SSZ-13 also exhibits a Brönsted acidity that is in the range of 2.0 mmol/g to 3.4 mmol/g as measured by ammonia temperature programmed desorption. A catalyst formed by substituting a metal into the framework of the zeolite provides for low temperature light-off of the NOx conversion reactions, while maintaining substantial performance at higher temperatures demonstrating hydrothermal stability.

Abstract: An oxygen storage material (OSM) that exhibits enhanced redox properties, developed mesoporosity, and a resistance to sintering. The oxygen storage material (OSM) has a high oxygen storage capacity (i.e., OSC>1.5 mmol H2/g) and enhanced reducibility (i.e., bimodal TPR-H2 profile with two Tmax in the temperature range from 150° C. to 550° C.). The OSM is suitable for use as a catalyst and a catalyst support. The method of making the oxygen storage material comprises the preparation of a solution containing zirconium, cerium, rare earth and transition metal salts, followed by the co-precipitation of all constituent metal hydroxides with a base.

Abstract: A crystalline Boehmite product and a method of forming said product is provided in which the crystalline Boehmite exhibits an average particle size (d50) that is less than 7,000 nanometers. This method comprises preparing an aqueous slurry by mixing together water, large aluminum oxide precursors, a highly dispersible Boehmite grade, and optionally, an organic dispersing agent; adjusting the pH of the slurry; heating the slurry for a predetermined duration of time; collecting the slurry to form a wet cake; and drying the wet cake to obtain the crystalline Boehmite product. The crystalline Boehmite product may be mixed with a plastic resin to form a flame retardant plastic mixture, which can be subjected to a conventional plastic processing method to form a flame retardant composite.

Abstract: A wash coat is formed by combining platinum group metals (PGM) and an adhesive with a mixture of catalyst support materials according to the relationship (α)RE-Ce—ZrO2+(β)CZMLA+(1−α−β)RE-Al2O3. The RE-Ce—ZrO2 is a commercial material of rare earth elements stabilized ceria zirconia having a weight ratio (α) ranging from 0 to about 0.7; CZMLA is a catalyst support material comprising a core support powder coated with a solid solution and has a weight ratio (β) ranging from about 0.2 to about 1 such that (α+β)≦1. RE-Al2O3 is rare earth element stabilized alumina having a weight ratio equal to (1−α−β). The wash coat exhibits a lower activation temperature compared with traditional wash coat formulations by at least 50° C. This wash coat also requires less RE-Ce—ZrO2 oxide and/or less PGM in the formulation for use as an emission control catalyst for gasoline and diesel engines.

Abstract translation: 根据（α）RE-Ce-ZrO2 +（β）CZMLA +（1-α-β）RE-Al2O3的关系，通过将铂族金属（PGM）和粘合剂与催化剂载体材料的混合物组合形成洗涤涂层。 RE-Ce-ZrO 2是重量比（α）为0至约0.7的稀土元素稳定二氧化铈氧化锆的市售材料; CZMLA是一种催化剂载体材料，其包含涂覆有固溶体的核心载体粉末，其重量比（β）为约0.2至约1，使得（α+β）≤1。 RE-Al2O3是重量比等于（1-α-β）的稀土元素稳定的氧化铝。 洗涤涂层与传统的洗涂剂配方相比，表现出比至少50℃更低的活化温度。该洗涤涂层在制剂中还需要较少的RE-Ce-ZrO 2氧化物和/或较少的PGM用作汽油的排放控制催化剂 和柴油发动机。

A gel composition formed upon using this method includes one or more sources of silica, alumina, organic structure directing agents (OSDA), and alkali metal ions; zeolite seeds; and water. This gel composition is defined by the molar ratios of: SiO2/AI2O3 18:1 to 100:1; M2O/SiO2 0.15:1 to 0.30:1; ROH/SiO2 0.05:1 to 0.13:1; and H2O/SiO2 5:1 to 20:1; wherein M is the alkali metal ion and R is an organic moiety derived from the OSDA. This gel composition, after reacting at a temperature between 135° C. to about 200° C. for 10 hours to 168 hours forms the crystalline AEI-type zeolite having a silica to alumina ratio (SiO2:AI2O3) that is greater than 15:1.
