The influence of the SBA-15 porosity on the H2 adsorption of nickel-silica materials

Abstract

Hydrogen is considered as a promising renewable nonpolluting alternative to fossil fuels, which will play a major role in future energy system. However, hydrogen storage is one of the bottlenecks for the applications in automobile. Several storage methods have been investigated to develop efficient technologies. Hydrogen storage in sorbents is the most promising technology with respect to efficiency and safety 1. In this work, ordered mesoporous SBA-15 materials were modified with Ni and were reduced in a H2 flow. The materials were characterized and the hydrogen storage capacity of the materials was evaluated at 77 K and room temperature, and at low and high-pressure conditions respectively.
