Abstract

Today, due to the increasing needs of mankind for progress and in the course of that progress, the need for energy has led to the shortage and depletion of the common and used fuels in the world, i.e. fossil fuels. Renewable energies have been highly regarded as sources for estimating this need. Among renewable energies, hydrogen as a clean energy source with high potential has a promising perspective to replace fossil fuels. In this project, nanoporous carbon substrate produced by palm kernel and its storage capacity has been investigated by chronopotentiometric method in electrochemical method. Date palm seed, as one of the major waste biomasses, was evaluated for its potential to become a suitable precursor for the preparation of porous carbon using potassium hydroxide as an activating agent through process optimization. In this project, nanoporous carbon was chosen as a hydrogen absorbent substrate and palladium metallic nanoparticles were selected as absorbents and catalysts. The appropriate price of the prepared nanoporous carbon substrate was put on the agenda and investigated for storage tests because of the simple and low-cost manufacturing and preparation steps. To make porous carbon, 10 grams of date kernel powder was mixed with potassium hydroxide solution (20% by volume) and after burning, washing and drying, it was used in hydrogen storage tests. In order to investigate the structural characteristics of nanoparticles and the final produced structure, scanning electron microscope analysis, X-ray diffraction spectroscopy analysis, Fourier transform infrared spectroscopy, visible spectrometer analysis and BET analysis were performed and the obtained results were analyzed and the structure of nanoparticles They confirmed the porous carbon. The size of porous carbon nanoparticles was found to be about 449.35 nm and the size of the holes was 2.6 nm, which shows that these particles are of nanoporous type. According to the X-ray diffraction analysis, the nano
