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: A low-temperature dehydrogenation method includes a dehydrogenation reaction of a reactant including a piperidine-based compound substituted with one or more alkyl groups. The dehydrogenation reaction takes place in the presence of a catalyst including an active metal. The active metal includes platinum (Pt), palladium (Pd), or a mixture thereof that is supported on a carrier including a composite metal oxide having alumina (Al2O3) and an additional metal oxide different from alumina, at a low temperature of 150° C. to 250° C., to produce hydrogen.
