A catalyst for decomposing high-concentration hydrogen peroxide comprises an active layer on a carrier comprising gamma-phase alumina. The carrier can also comprise aluminum, with the gamma-phase alumina forming a passivating layer on the surface of the aluminum. The active layer can comprise platinum. Apparatus for decomposing hydrogen peroxide can include the catalyst in a decomposition chamber arranged to receive hydrogen peroxide. The apparatus can be used as a thruster, comprising a nozzle arranged to generate thrust by directing exhaust gases in a specific direction. For example, the thruster can be a monopropellant, bipropellant, or hybrid thruster. In other embodiments, the apparatus can be used as a gas generator or a fuel cell.
