Platinum/carbon nanotube nanocomposite synthesized in supercritical fluid as electrocatalysts for low-temperature fuel cells
Article Abstract:
Carbon nanotube (CNT)-supported Pt nanoparticle catalysts are synthesized in supercritical carbon dioxide (scCO2) using platinum(II) acetylacetonate as metal precursor. The structures of the catalysts are characterized with transmission electron micrograph (TEM) and X-ray photoelectron spectroscopy (XPS) TEM images show that the platinum particles' size in the range of 5-10 nm.

Mechanism of the hydrogen/platinum(111) fuel cell
Article Abstract:
The structure of the water chain is drawn with alternating orientation of the water molecules to keep the O-H-O bond from bending. The tetrahedral geometry of the water potential and the large dipole create two different water 'phases' for positively and negatively charged electrodes, which is long chains at positive potentials and a honeycomb lattice for negative potentials.
