Low-temperature hydrogen desorption from Mg(BH4)2 catalysed by ultrafine Ni nanoparticles in a mesoporous carbon matrix
Abstract
Homogenously dispersed, ultrafine Ni nanoparticles (Ni NPs) have been grown in a mesoporous carbon (MC) matrix (MC-Ni<sub>insitu</sub>) and efficiently catalyze low-temperature hydrogen desorption from Mg(BH<sub>4</sub>)<sub>2</sub>. The onset desorption temperature (T<sub>onset</sub>) of this MC-Ni<sub>insitu</sub>-Mg(BH<sub>4</sub>)<sub>2</sub> system is 44 <sup>o</sup>C compared to 275 <sup>o</sup>C (T<sub>onset</sub>) for pure Mg(BH<sub>4</sub>)<sub>2</sub>. This is the lowest value reported for hydrogen desorption from this metal hydride. The activation energy (E<sub>a</sub>) of MC-Ni<sub>insitu</sub>-Mg(BH<sub>4</sub>)<sub>2</sub> was determined to be 21.3 kJ/mol which is less than half the value of 45.9 kJ/mol for pure Mg(BH<sub>4</sub>)<sub>2</sub>. We ascribe this reduction to the synergistic effects of nanoconfinement and the homogeneously dispersed, ultrafine Ni NPs active sites in the mesoporous carbon.
