Improvement electrolysis of water efficiency for hydrogen production using stainless steel nanoparticles synthesized by laser technique

Abstract

Hydrogen generators offer the possibility of zero-emissions electricity generation. The current research involves improving the hydrogen generator performance of electrolysis of water by increasing electrolyte efficiency. Stainless steel nanoparticles (SSNPs) were prepared using Pulsed Laser Ablation in Liquid (PLAL) technique and then (0.004g) added to the electrolyte. For the purpose of comparison, the same generator was operated but using an electrolyte composed of a strong alkali (NaOH) dissolved in high purity water. The amount of hydrogen produced during the operating period was measured and the maximum product quantity was 230 ml within one minute. Nanoparticles were characterized by means of AFM test, PH measurement, and an Electrical Conductivity (EC) test of the nano solution.
