Hollow nickel-coated silica microspheres containing rhodium nanoparticles for highly selective production of hydrogen from hydrous hydrazine

Abstract
Hollow nickel-coated microspheres containing Rh nanoparticles (Rh/Ni@SiO2) generate hydrogen (H2) from hydrazine (H2NNH2) with over 99% selectivity within 1.5 h at 25 °C.
