  • METAL OXIDE CATALYST FOR SELECTIVE CATALYTIC REDUCTION
    Publication number: 20240375086
    Abstract: A non-vanadium based metal oxide catalyst composition is provided. The catalyst composition comprises at least one metal oxide, comprising manganese oxide and being dispersed on the support, and a support comprising particles of composite oxide of aluminum and at least one metal selected from cerium, manganese and titanium, wherein aluminum is present in the composite oxide in an amount of from 50% to 80% by weight, calculated as Al2O3, based on the total weight of the composite oxide, and wherein manganese oxide is present in the metal oxide catalyst composition in an amount of from 2.5% to 10% by weight, calculated as MnO2, based on the total weight of the metal oxide catalyst composition.

  • Hybrid epoxy-acrylic with zirconium oxide nanocomposite for curable coatings
    Patent number: 9638834
    Abstract: A composition includes: a continuous liquid phase including an acrylic monomer and an epoxy monomer; and a dispersed nanoparticulate including ZrO2 modified with an acrylic silane; and wherein the composition is transparent to visible light when coated on a lens. In addition, a method including the steps of: mixing an acrylic silane and a methanol-based ZrO2 sol to create a methanol-based silane-modified ZrO2 sol; then mixing at least an acrylic monomer, an epoxy monomer, and the methanol-based silane-modified ZrO2 sol to obtain the composition. The composition can be adapted for coating and curing onto another substrate, such as an ophthalmic lens.
