Abstract
Nanoparticles, microflowers, and microspheres of zinc oxide have been synthesized in a large quantity via solution process at low temperature and were tested for the hydrogen adsorption studies. The experiments were carried out using Sievert's apparatus which resulted in highest hydrogen adsorption value for nanoparticles is similar to 1.220 wt%, whereas for microflower composed with thin sheets value reduced (similar to 1.011wt%) but in case of microspheres composed with nanoparticles having below one wt% (similar to 0.966 wt%). The FE-SEM and XRD clarify that the obtained products are crystalline with wurtzite phase. Including morphological and crystalline characterization, the surface area of the prepared nano-and microstructures was observed with BET.
