Preparation and Characterization of ZnO Nanoparticles by Laser Ablation in NaOH Aqueous Solution

In the recent years, laser ablation in liquid has become an increasingly important technique for the fabrication of NPs. this paper reports our recent studies on the generation of ZnO NPs by ablation of metal targets in aqueous environments using Q-switch Nd-YAG laser (λ=532nm) immersed in NaOH (0.1M). The Surface topography studied by atomic force microscopy revealed wider size distributio...

Dynamics of dihydrogen bonding in aqueous solutions of sodium borohydride.

Dihydrogen bonding occurs between protonic and hydridic hydrogens which are bound to the corresponding electron withdrawing or donating groups. This type of interaction can lead to novel reactivity and dynamic behavior. This paper examines the dynamics experienced by both borohydride and its dihydrogen-bound water solvent using 2D-IR vibrational echo and IR pump-probe spectroscopies, as well as...

Bursting Dynamics in Molecular Hydrogen Generation via Sodium Borohydride Hydrolysis

The hydrolysis of borohydride salts is a promising process for the generation in situ of pure molecular hydrogen that can be used as an alternative fuel. One of the obstacles toward its concrete application in the realm of green energy resides in nonlinear behaviors of H2 delivery during the reaction development. In particular, we have recently shown that this system behaves like a chemical osc...

Electronic structure of aqueous borohydride: a potential hydrogen storage medium.

Borohydride salts have been considered as good prospects for transportable hydrogen storage materials, with molecular hydrogen released via hydrolysis. We examine details of the hydration of sodium borohydride by the combination of X-ray absorption spectroscopy and first principles' theory. Compared to solid sodium borohydride, the aqueous sample exhibits an uncharacteristically narrow absorpti...

Dynamic Modeling of Hydrogen Generation via Hydrolysis of Sodium Borohydride

This paper deals with the dynamic modeling of a hydrogen production system using gPROMS. The model includes mass balances, liquid-gas equilibrium relations, mass transfer laws and kinetic reaction equations. The initial reaction mixture is a sodium borohydride solution that reacts via a self-hydrolysis mechanism in the presence of water. The behavior of this system was measured in terms of prod...
