Fabrication of Pt-doped carbon aerogels for hydrogen storage by radiation method
2018
Abstract A radiation method was investigated to fabricate Pt-doped carbon aerogels (CAs Pt). The physicochemical properties of the pristine CAs and CAs Pt were systematically characterized by X-ray diffraction, scanning electron microscope, transmission electron microscopy, and nitrogen adsorption measurements. The results showed that not only a great number of Pt nanospheres but also many Pt nanoparticles presented in the network of CAs after radiation. The influence of Pt doping on the hydrogen uptake capacity of CAs was studied. In comparison with the pristine CAs, it was remarkable that the hydrogen uptake capacity of the CAs Pt had been significantly enhanced, which was contributed by the hydrogen spillover of Pt.
