Carbon footprint analysis in the preparation of the platinum nanophase electro catalyst composite electrode

A new approach in the use of PGMs for the highly catalytic activity in the production of hydrogen by water electrolysis, is to reduce PGMs into nanometer size (nanophase), then integrate them into electrodes. Water electrolysis is an environmental friendly process of producing hydrogen. This study was for the cognition of likely impacts to environment with regard to the manufacturing process of the composite electrode. The Life Cycle Inventory Assessment method and the carbon footprint calculation in the preparation of the composite electrode were essentially assisted by the Umberto for carbon footprint software, which helped to build an inventory analysis and provided a useful database of materials with respective carbon footprints. Direct emissions were likely involved when heating, calcinating, drying materials. Palliative recommendations were suggested in accordance with the types of emissions identified
