By nitrogen doping with ammonia treatment and platinum nanoparticle decoration, the methane and carbon dioxide storage capacities of activated carbon were enhanced, with a preference for CO2 storage. Nitrogen doping improved micropore properties, while platinum decoration had an opposite effect on gas storage.
Activated carbon (AC) was treated with ammonia for nitrogen doping and then was further anchored with platinum nanoparticles through ultrasound-assisted impregnation method. Methane (CH4) and carbon dioxide (CO2) storage of the pristine and modified activated carbon were determined at ambient temperature. All the samples showed high storage capacities with preference towards carbon dioxide storage, which would be favorable for both energy and environmental applications. Ammonia treatment slightly improved the storage of both CH4 and CO2 for all the samples, which could be attributed to the little improvement in the micropore properties upon nitrogen doping. Platinum decoration had an opposite influence on both CH4 and CO2 storage, which might be due to the absence of metal encouraging storage mechanism such as gas dissociation or reconstruction on platinum's surface in addition to the harmful effect of metal pore-blocking and higher density of metal particles.
