Superior hydrogen performance of formed carbon modified MgH composites.

The MgH-carbonic combustion product of the anthracene (CCPA) composite was synthesized by hydrogen combustion and mechanically ball-milled method to simultaneously achieve confinement by the formed amorphous carbon. The amorphous carbon derived from the carbonic combustion product of anthracene in the MgH-CCPA composite led to a significant increase in hydrogen sorption characteristics. The onset dehydrogenation temperature for the MgH-CCPA composite was reduced to 589 K, which was 54 K less than that of pure milled MgH.

A novel CeFeZrO solid solution with high catalytic activity for hydrogen storage in MgH.

The effect of the solid solution CeFeZrO, successfully prepared by a hydrothermal synthesis method, on the hydrogen sorption properties of MgH is systemically investigated. The CeFeZrO-modified MgH composite exhibits remarkable hydrogen kinetics properties and thermodynamics behavior compared to those of as-milled MgH, with a reduction in the initial desorption temperature of approximately 82 K. With respect to the hydrogen kinetics, the CeFeZrO-added sample could uptake approximately 5.
