Breakthrough in Hydrogen Energy Research: Reducing Dependence on Fossil Fuels

Strategic Insights -

Research investigators in Gansu, People's Republic of China, have made a significant discovery in the field of hydrogen energy production, stating that the development of hydrogen energy can help reduce dependence on fossil fuels and achieve low carbon emissions. According to the study, hydrogen production from electrolysis water is one of the clean technologies that can contribute to a more sustainable energy future. The research, funded by Major science and technology projects of Gansu Province and National Natural Science Foundation of China, has been peer-reviewed and published in the journal Fuel.

Key Takeaways:

  • The study aims to design a catalyst with a structure of amorphous Co(OH)2 modified Co (1 1 1) using cobalt-containing waste to improve the efficiency of hydrogen production from water electrolysis.
  • The researchers prepared a catalyst using cobalt-containing waste and achieved excellent activity with an overpotential of only -56 mV at a current density of -10 mA/cm2 and a Tafel slope of 78.6 mV/dec.
  • The use of cobalt-containing waste as the raw material for production of the electrode reduces the cost and harm to the environment.
