Abstract: The present invention provides a solid-phase catalyst for decomposing hydrogen peroxide comprising a permanganate salt and a manganese (II) salt. The solid-phase catalyst stays a solid state in the form of nanoparticles at the time of hydrogen peroxide decomposition, and thus can be recovered for reuse and also has an excellent decomposition rate. In the method for producing a solid-phase catalyst for decomposing hydrogen peroxide according to the present invention, a solid-phase catalyst is produced from a solution containing a permanganate salt, a manganese (II) salt, and an organic acid, so that the produced solid-phase catalyst is precipitated as a solid component even after a catalytic reaction, and thus is reusable and environmentally friendly, and cost reduction can be achieved through the simplification of a catalyst production technique.

Abstract: The present invention relates to a monolith catalyst for reforming reaction, and more particularly, to a thermally stable (i.e. thermal resistance-improved) monolith catalyst for reforming reaction having a novel construction such that any one of Group 1A to Group 5A metals are used as a barrier component in the existing catalyst particles to inhibit carbon deposition occurring during the reforming reaction in a process for formation of a reforming monolith catalyst while improving thermal durability as well as non-activation of the catalyst due to a degradation.

Abstract: Disclosed herein are an activated carbon catalyst for hydrogen peroxide decomposition, a preparation method thereof and a hydrogen peroxide decomposition method using the same. The activated carbon catalyst for hydrogen peroxide decomposition, provided in an aspect of the present invention may be easily prepared through the carbonization and activation of an ion exchange resin, and safer and higher decomposition efficiency of hydrogen peroxide may be achieved than the conventional catalyst for hydrogen peroxide decomposition through the control of the manganese content and pore properties in the catalyst.
