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 negative electrode for use in an electrochemical cell, such as a lithium-ion secondary battery that includes a positive electrode with an active material that acts as a cathode and a current collector; a negative electrode with an active material that acts as an anode and a current collector; a non-aqueous electrolyte; and a separator placed between the positive and negative electrodes. The negative electrode, includes an inorganic additive dispersed therein or applied as a coating thereon, the inorganic additive being in the form of one or more zeolites having a Si:Al ratio ranging from 1-50 that absorbs one or more of moisture, free transition metal ions, or hydrogen fluoride that become present in the cell. One or more of the cells may be combined in a housing to form a lithium-ion secondary battery.

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 nanocrystal-sized cerium-zirconium-aluminum mixed oxide material includes at least 20% by mass zirconium oxide; between 5% to 55% by mass cerium oxide; between 5% to 60% by mass aluminum 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-aluminum mixed oxide exhibits hierarchically ordered aggregates having a dso particle size less than 1.5 μm, and retains at least 80% of surface area and pore volume after ageing at temperature higher than 1000° C. for at least 6 hours. The nanocrystal-sized cerium-zirconium-aluminum mixed oxide material is prepared using a co-precipitation method followed by milling the dried and calcined oxide material. The nanocrystal-sized cerium-zirconium-aluminum mixed oxide material forms a particulate filter that may be used in an exhaust system arising from a gas or diesel engine.
