Hydrogen, H2, is a globally accepted clean fuel. The use of hydrogen fuel cells in vehicles or in portable electronic devices requires lightweight H2 storage or “on-board” hydrogen generation, for which the most important are safety, ease to control and fast kinetics of the hydrogen release along with a high hydrogen content. Here we report excellent liquid-phase hydrogen generation systems suitable for use as portable hydrogen sources, which are based on metal nanoparticle-catalyzed hydrolysis of ammonia borane (NH3BH3), complete decomposition of hydrous hydrazine (H2NNH2) and decomposition of formic acid. The metal nanoparticles catalysts immobilized by the double-solvents method (DSM) inside the pores of MOFs, by the non-noble metal sacrificial approach (NNMSA) to reduced graphene oxide and by the weakly-capping growth approach (WCGA) to carbon nanospheres will be discussed. The use of soluble porous organic cages as a stabilizer and homogenizer toward the homogenization of heterogeneous metal nanoparticle catalysts with enhanced catalytic performance will also be discussed.
