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.

Abstract: A cell 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. At least one of the cathode, the anode, the electrolyte, and the separator includes an inorganic additive in the form of a transition phase alumina or a type of boehmite that absorbs one or more of moisture and/or hydrogen fluoride (HF) that become present in the cell. One or more cells may be combined in a housing to form a lithium-ion secondary battery. The inorganic additive may also be incorporated as a coating applied to the internal wall of the housing.

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 method of forming an AFX zeolite in a hydrothermal synthesis that exhibits a silica to alumina (SiO2AI2O3) molar ratio (SAR) that is between 8:1 and 26:1; 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 AFX zeolite also exhibits a Brönsted acidity that is in the range of 1.2 mmol/g to 3.6 mmol/g as measured by ammonia temperature programmed desorption. A catalyst formed by substituting a metal into the framework of the zeolite exhibits about a 100% conversion of NO emissions over the temperature range of 300° C. to 650° C.

Abstract: An inorganic oxide material doped with nano-rare earth oxide particles that is capable of trapping one or more of NOx or SOx at a temperature that is less than 400° C. The nano-rare earth oxide particles have a particle size that is less than 10 nanometers. The catalyst support can trap at least 0.5% NO2 at a temperature less than 350° C. and/or at least 0.4% SO2 at a temperature less than 325° C. The catalyst support can trap at least 0.5% NO2 and/or at least 0.2% SO2 at a temperature that is less than 250° C. after being aged at 800° C. for 16 hours in a 10% steam environment. The catalyst support exhibits at least a 25% increase in capacity for at least one of NOx or SOx trapping at a temperature that is less than 400° C. when compared to a conventional rare earth doped support in a 10% steam environment.

Abstract: Mesoporous, zirconium-based mixed oxides and a method of making the same comprises: injecting a polyvalent metal-containing solution into an electrolyte solution to form a mother liquor; forming a precipitate; aging the precipitate in the mother liquor to form the mixed oxides; washing the mixed oxides with an aqueous medium; drying and collecting the mixed oxides. The pH of the electrolyte solution exceeds the isoelectric point for zirconium-based mixed oxides. The mixed oxides exhibit a single particle size distribution, improved Ce02 reducibility in the presence of Rhodium, a decrease in surface area after calcination (800-1 100° C.) that is not more than 55%, and a tetragonal/cubic structure after calcination. After calcination at 1 100° C. for 10 hours in air, the mixed oxides exhibit a surface area >25 m2/g, a pore volume >0.20 cm3/g, an average pore size >30 nm, and an average crystallite size between 8-15 nm.
