  • Publication number: 20210020954
    Abstract: The present disclosure relates to a fuel cell catalyst and a manufacturing method thereof. The fuel cell catalyst of the present disclosure can be used to manufacture a membrane electrode assembly having a catalyst layer of high density and high dispersion by solving the problem of aggregation of catalyst particles occurring during the formation of the catalyst layer, by using a catalyst including a polydopamine-coated support. In addition, the method for manufacturing a fuel cell catalyst of the present disclosure does not require a solvent because the catalyst including the polydopamine-coated support and the halide in solid phase are simply heat-treated by solid-to-solid dry synthesis and allows manufacturing of a fuel cell catalyst in short time because a washing process using a solvent and an extraction process for sampling are unnecessary after the synthesis.

  • Patent number: 10850270
    Abstract: Disclosed is a method for preparing a carbon-supported metal oxide and/or alloy nanoparticle catalyst. According to the method, a carbon-supported metal oxide and/or alloy nanoparticle catalyst is prepared by depositing metal oxide and/or alloy nanoparticles on a water-soluble support and dissolving the metal oxide and/or alloy nanoparticles deposited on the water-soluble support in an anhydrous polar solvent containing carbon dispersed therein to support the metal oxide and/or alloy nanoparticles on the carbon. The anhydrous polar solvent has much lower solubility for the water-soluble support than water and is used to dissolve the water-soluble support.

    Abstract: Disclosed are a metal single-atom catalyst and a method for preparing the same. The method uses a minimal amount of chemicals and is thus environmentally friendly compared to conventional chemical and/or physical methods. In addition, the method enables the preparation of a single-atom catalyst in a simple and economical manner without the need for further treatment such as acid treatment or heat treatment. Furthermore, the method is universally applicable to the preparation of single-atom catalysts irrespective of the kinds of metals and supports, unlike conventional methods that suffer from very limited choices of metal materials and supports. Therefore, the method can be widely utilized to prepare various types of metal single-atom catalysts. All metal atoms in the metal single-atom catalyst can participate in catalytic reactions. This optimal atom utilization achieves maximum reactivity per unit mass and can minimize the amount of the metal used, which is very economical.
