Metal-Organic Frameworks (MOFs) Prove Efficient in Optimizing Hydrogen Production Process
Tehran, Iran | Posted on December 10th, 2015The study proves the positive effect of MOFs and its results can help the production of green energies and decrease the cost of production of fuel cells.
Hydrogen storage in high pressure capsules is a big challenge. A suggestion to overcome this problem is the electrochemical production of hydrogen in the entrance of fuel in a fuel cell. However, this process has slow electron transfer kinetics at the surface of normal electrodes. The aim of the research was to modify the electrode surface by using nanomaterials to increase the kinetics of hydrogen evolution reaction (HER).
In fact, when the electrode surface is modified, the rate of electron transfer increases on the surface. In this research, the objective has been fulfilled by using the nanocomposite of copper/nanoporous carbon derived from MOF-199.
Based on the results, the presence of the nanocomposite on the surface of the modified electrode improves electron transfer in hydrogen evolution reaction. In other words, the modified electrode enables the faster and simpler electrochemical production of hydrogen as a green fuel to be used in hydrogen/oxygen fuel cells. In addition, this electrode reduces production cost due to the lack of the use of the expensive platinum metal in the electrode structure.
Production of electrical energy as green energy by using fuel cells, including hydrogen/oxygen fuel cell, which results in the production of water as the final product in the reaction, does not pollute the environment at all.
Results of the research have been published in Energy, vol. 90, Part 1, 2015, pp. 1075-1081.
