Mono-dispersed transition metal nanoparticles on boron-substituted carbon support and applications in hydrogen storage

► Methods to prepare uniform transition metal nanoparticles on boron-substituted carbon (BCx) support. ► Good thermal stability of metal nanoparticles (Pt, Pd, Zr, Ti, etc) nanoparticles on BCx. ► Pt/BCx material shows dramatically increase in hydrogen adsorption capability at ambient temperature.
