  • Publication number: 20240396053
    Abstract: A method for forming an oxygen reduction reaction (ORR) catalyst (200, 900) may include providing a carbon (210, 910) supported platinum nanoparticle (220, 920) substrate (Pt/C) (110) and applying a tungsten nitride (WN) film (940) onto the surface of the Pt/C substrate (210, 220, 910, 920) using atomic layer deposition (ALD) (120). The Pt/C substrate (210, 220, 910, 920) with the WN film (940) may then be oxidized at a low temperature (130) and annealed at a high temperature in order to reduce WN to metallic tungsten (W) (140). The metallic W forms a blocking layer (230, 930) over coarse Pt nanoparticles (220, 920) and improves the activity and the durability of the Pt/C catalyst (900, 200) when used in fuel cells or related applications.

  • Publication number: 20220387969
    Abstract: A method for forming an amine-functionalized solid CO2 sorbent for carbon capture may include providing a support material and applying at least one cycle of molecular layer deposition (MLD) with an amine precursor onto the surface of the support material. An amine layer formed on the support material contains amine groups/amine-containing ligands to adsorb CO2 onto the support material in a low temperature operating window for adsorption and desorption without the loss of active sites.

  • Publication number: 20200274138
    Abstract: The invention relates to lithiated mixed metal compositions having ultrathin film coatings of varying thicknesses on lithium ion sites and on metal oxide sites, wherein the thickness of the ultrathin film at least partially covering the metal oxide sites is greater than the thickness of the ultrathin film at least partially covering the lithium ion sites. Also disclosed is a method for forming the compositions, comprising selectively coating one area of a multi-component substrate. Materials such as mixed metal oxides, for use in lithium battery electrodes, may be improved by a coating which preferentially deposits onto one or more elements in the mixed material but not another.
