A team of scientists led by Dr. Edison Ang at NTU in Singapore, in collaboration with researchers at Zhejiang Ocean University, has developed a groundbreaking new design for green hydrogen production using carbon nitride material. The key innovation lies in the Janus homojunction design, where two layers of carbon nitride are stacked together in a unique arrangement rich in nitrogen and carbon, creating a powerful internal electric field that significantly enhances the efficiency of splitting water molecules to produce hydrogen. This design makes the process up to 14 times more efficient than previous methods. The breakthrough is crucial as it enables the production of green hydrogen, a clean and sustainable energy source that can help reduce harmful emissions and combat climate change. By improving the efficiency of green hydrogen production through innovative material design, the world is a step closer to a cleaner, more sustainable future with reduced dependence on fossil fuels. The study detailing this innovation has been published in Materials Horizons, highlighting the potential of this design to revolutionize clean energy production and contribute significantly to the fight against climate change.
