  • Patent number: 11994345
    Abstract: The present invention describes an improved process for the commercial scale production of high-quality catalyst materials. These improved processes allow for production of catalysts that have very consistent batch to batch property and performance variations. In addition these improved processes allow for minimal production losses (by dramatically reducing the production of fines or small materials as part of the production process). The improved process involves multiple steps and uses calcining ovens that allow for precisely control temperature increases where the catalyst is homogenously heated. The calcining gas is released into a separate heating chamber, which contains the recirculation fan and the heat source.

  • Patent number: 11978912
    Abstract: Atomically dispersed platinum-group metal-free catalyst and method for synthesizing the same. According to one embodiment, the catalyst is made by a method in which, in a first step, a metal oxide/zeolitic imidazolate frameworks (ZIF) composite is formed by combining (i) nanoparticles of an oxide of at least one of iron, cobalt, nickel, manganese, and copper, (ii) a hydrated zinc salt, and (iii) an imidazole. Then, in a second step, the metal oxide/ZIF composite is thermally activated, i.e., carbonized, to form an M-N—C catalyst. Thereafter, the M-N—C catalyst may be mixed with a quantity of ammonium chloride, and then the M-N—C/NH4Cl mixture may be pyrolyzed. The foregoing NH4Cl treatment may improve the intrinsic activity of the catalyst. Then, a thin layer of nitrogen-doped carbon may be added to NH4Cl-treated M-N—C catalyst by chemical vapor deposition (CVD). Such CVD treatment may improve the stability of the catalyst.

  • Patent number: 11969716
    Abstract: This application discloses a silicon carbide (SiC)-loaded graphene photocatalyst for hydrogen production under visible light irradiation and a preparation method thereof. Pure SiC and pure black carbon are respectively prepared and mixed to obtain a mixture with a resistance less than 100?. Then the mixture was vacuumized and processed with a current pulse with an increasing voltage until a breakdown occurs, and subjected to ultrasonic stirring, centrifugal washing and vacuum drying in turn to obtain the SiC-loaded graphene photocatalyst. By means of the current pulse, a heterojunction is formed between SiC and graphene to improve the catalytic activity of the photocatalyst; and the photocatalytic hydrogen production rate of SiC nanoparticles can be enhanced after loaded on the graphene.

  • Patent number: 11932558
    Abstract: A piezoelectric polymer used as a piezocatalyst, and methods of manufacture and use therefor. A preferred piezoelectric polymer is poly(vinylidene difluoride) (PVDF) due to its piezoelectric response and good flexibility. The polymer can be doped with a metal, metal salt, metal carbonyl, metal oxide such as ZnO, Co2O3, or TiO2, or ion such as Cr3+, Co2+, or Zn2+. The dopant can be chosen so that when the polymer is PVDF the dopant increases the amount of ?-phase PVDF and/or ?-phase PVDF relative to ?-phase PVDF, thereby increasing the piezocatalytic response of the polymer. The compound to be decomposed can be adsorbed on the surface of the piezoelectric polymer. Applications include wastewater treatment, CO2 capture and reduction, hydroformylation, water splitting, and ammonia synthesis.
