The quest for clean and sustainable energy sources has led scientists to focus on harnessing the power of hydrogen, known for its high energy density and potential as a clean fuel. In Hyderabad, India, scientists at the CSIR-Indian Institute of Chemical Technology (IICT) have made a breakthrough in green hydrogen production by developing a highly efficient catalyst, 'cobalt(III) based bis-terpyridine'. This new catalyst has wide light-harvesting capabilities, enabling the harnessing of solar energy to produce hydrogen from water. Unlike traditional fossil fuel-dependent methods, this system relies solely on solar energy and a photo-electro-chemical setup for the water-splitting reaction. Lead scientist Chandrasekharam highlights the significance of this technology in paving the way for large-scale hydrogen production, emphasizing the importance of affordable and scalable green energy solutions. The innovative catalyst's ability to convert solar energy into chemical energy efficiently marks a significant advancement towards a greener and more sustainable energy future. This research, published in the 'Sciencedirect Next Energy' journal, not only showcases the potential of this catalyst but also sets the stage for further advancements in the field of green energy research.
