  • Method for preparing dicarbamate compounds from diamines and the catalyst thereof
    Patent number: 11565997
    Abstract: The present invention relates to a method of directly preparing a dicarbamate compound from a diamine compound, and more particularly to a method of directly preparing a dicarbamate compound by reacting a diamine compound with an alcohol compound in the presence of a mixed gas of carbon monoxide (CO) and oxygen (O2) using a Pd/MOx catalyst configured such that a palladium (Pd) active metal is supported on a metal oxide or metalloid oxide carrier.

  • Hydrogen Storage Materials Comprising Naphtalene Group and the Method for Hydrogen Storage and Release Using the Same
    Publication number: 20220033258
    Abstract: Proposed are a naphthalene-based hydrogen storage material including a naphthalene group, the naphthalene-based hydrogen storage material being capable of being used as a hydrogen storage media for supplying hydrogen to a device using hydrogen such as a fuel cell and a hydrogen combustion device, and to a method of storing and releasing hydrogen using the same. The hydrogen storage material can exhibit a significantly high hydrogen capacity, and can have excellent cost competitiveness with the use of a low-cost organic compound which is commercially available in the art.
