The catalyst uses ?-MoC1-x as carrier, and has metal that has the mass fraction ranging from 1-100% and that is dispersed on carrier ?-MoC1-x in the single atom form. The catalyst provided in the present application can be adapted to a wide alcohol/water proportion in hydrogen production based on aqueous-phase reforming of alcohols, outstanding hydrogen production performance can be obtained at a variety of proportions, and catalysis performance of the catalyst is much higher than that of metal loaded with an oxide carrier. Especially when the metal is Pt, catalysis performance of the catalyst provided in the present application in the hydrogen production based on aqueous-phase reforming of alcohols is much higher than that of a Pt/?-MoC1-x load-type catalyst on the ?-MoC1-x carrier on which Pt is disposed on a layer form in the prior art.

Abstract: A self-generating resistance apparatus for fitness and rehabilitation equipments comprises a bracket, a flywheel, a power generator, a belt and a resistance mechanism. The flywheel is rotating mechanism that provides inertia, and has a transmission shaft coupled to the power source of the fitness or rehabilitation equipment, and an external ring coupled to a pulley of the power generator by a belt. When a user steps on an exercise mechanism of the equipment, the flywheel drives the power generator to rotate and generate electric current. Since the power generator is installed outside the flywheel, the difference between the diameters of the pulley and the external ring causes a very large rotating speed ratio, and a large power approaching to the power generated by a large power generator can be produced.
