Multi-walled carbon nanotubes were synthesized by the catalytic decomposition of acetylene at 750oC over sepiolite powder, which was treated with aqueous cobalt nitrate. It is expected that the composite with high specific area will have high capacity of hydrogen storage.
Photochargeable behavior of hydrogen storage alloy electrode modified with TiO_2 nanoparticles(MH/TiO_2) was investigated by measuring its photocharge-discharge characteristics. The results showed the MH/TiO_2 electrode could store light energy photoelectrochemically when it was illuminated. The potential of the MH/TiO_2 electrode could be charged to 0.843 V.The discharge time of the MH/TiO_2 electrode increased with increasing the illuminating time, The mechanism of photochargeable behavior of the MH/T...
