Studies of hydrogen adsorption on ni-modified mcm-41 mesoporous materials.

MCM-41 mesoporous materials were prepared modified with different Ni contents, as promising materials for hydrogen storage. The final materials were reduced for studying the metallic nickel effect.

description MCM-41 mesoporous materials were prepared modified with different Ni contents, as promising materials for hydrogen storage. The final materials were reduced for studying the metallic nickel effect. The Ni/MCM-41 samples were characterized for different experimental techniques such as TPR, XRD and N2 adsorption-desorption. The hydrogen storage capacity of the materials was evaluated at 77 K and room temperature, and at low and high-pressure conditions respectively. In this study, we focused on the role of dispersed nickel as a way of promoting the interaction with hydrogen as an alternative to improve hydrogen storage materials. The results obtained show that the amount of hydrogen stored was highly enhanced by the dispersion of small amounts of Ni nanoparticles both at 77 and 298 K, indicating that these materials could be used for hydrogen storage in cryogenic and room temperature conditions.
