Ammonia (NH3) has attracted much attention in recent years because it provides a source of hydrogen for fuel cells, and it is easier to be liquefied and transported than hydrogen. Moreover, ammonia itself can serve as a fuel for power generation other than petroleum and coal. So there is a huge demand for producing ammonia. Ammonia production consumes around 2 percent of the world's total energy production and releases 500 Mt of carbon dioxide annually.
A research team led by scientists at City University of Hong Kong (CityU) developed a new kind of photocatalyst that can produce ammonia from atmospheric nitrogen at room temperature using sunlight. This new method outperformed the conventional way which causes massive carbon emissions. The research team believed that such technology of sustainable ammonia production would advance the development of the future nitrogen economy.
This research was led by Professor Leung Kwok Hi Michael, Shun Hing Education and Charity Fund Professor of Energy and Environment and Assistant Professor Dr. Shang Jin, both from CityU's School of Energy and Environment (SEE), as well as a scholar from Australia. Their findings were published in the scientific journal ACS Nano under the title "Atomically Dispersed Iron Metal Site in a Porphyrin-Based Metal-Organic Framework for Photocatalytic Nitrogen Fixation."
