Abstract
Waste from abundant zeolite was adorned with Titania (TiO2) and gold nanoparticles (Au NPs) produced by laser ablation in liquid (LAL) in deionized water, through physical stirring and loading conforming to the requirements for bio-friendly methods. The average size of Au NPs was measured to be ∼ 8 nm and the presence of TiO2 and Au NPs on the surface of zeolite was confirmed by analysis and they were assessed for the hydrogen production and adsorption, after the prepared nanocomposite was deposited on stainless steel mesh used as a working electrode. The results suggest that TiO2 and Au NPs positively influenced electrode’s performance and hydrogen adsorption/desorption was increased compared to initial zeolite. Au NPs optimization affirmed that adequate NPs loading is of monumental significance, in a way that the high amount of loading led to mitigating hydrogen adsorption. The hydrogen charge of 40.86 Cg−1 provides compelling evidence to introduce TiO2 and Au NPs as a catalytic candidate for the hydrogen production and adsorption.
