Demonstration of Controlled Hydrogen Release Using Rh@GQDs during Hydrolysis of NH3BH3

“…Zero-dimensional graphene quantum dots (GQDs) have recently attracted extensive concerns for their unique performances, such as low biotoxicity, wonderful hydrophilicity, and stable photoluminescence (PL) emission. − In addition, the band gap energy of GQDs can be tuned from 0 to 6 eV by controlling the sizes or modifying the surface chemical structures, being attributed to edge effect and quantum confinement effect. − Synthesis of GQDs with high quality has been actively explored for application in various domains, for example, catalysis, bioimaging, biosensors, drug carriers, and electronic devices. − Besides, as a frequently used H 2 storage material, NH 3 BH 3 (AB) is a hydrogen-rich inorganic hydride which has a high hydrogen content (19.6 wt %). − There are many advantages for the utilization of AB for H 2 evolution, that is, nontoxicity, excellent solubility, and high stability under ambient conditions. − Accordingly, AB is considered to be a promising contender in chemical hydrogen storage for future applications. − Today, among the various types of catalysts for H 2 evolution from AB, supported metal nanocatalysts have attracted widespread interest in chemistry and materials science due to their advantageous features, such as high efficiency, stability, and reusability for catalytic reactions. − …”
