Carbonic materials are considered to be one of the most promising materials for hydrogen adsorption and storage; they have different applications and fuel cells technology may be considered the most important of them. By using metals for doping them, the adsorption capacity increases, thus approaching “the target” of 6.5% weight ratio of H2 adsorbed in a substrate.

A comparative research related to hydrogen adsorption capacity of poly-aniline (PANI) doped with Platinum (Pt), Ruthenium (Ru) and Iridium (Ir) was carried out. PANI was obtained by chemical synthesis in laboratory conditions by using ultra pure reactants. The obtained PANI, acting as substrate, has been characterized in order to determine its BET and micro pores’ surface and structure. The doping procedure consists of a physical-chemical method which involves salts of the metals for doping and the use of ultrasounds for activating the substrate by inducing fractures within its internal structure. The adsorption capacity of the carbonic materials, which is a consequence of spill over phenomena, has been determined. The collected data related to the adsorption capacity have been processed by using dedicated software.
