A team of researchers from Japan's Hokkaido University, Australia's University of Technology Sydney, and other institutions have developed a groundbreaking catalyst, NiOOH-Ni, with remarkable properties for enhancing ammonia conversion efficiency. The catalyst, created by combining nickel with nickel oxyhydroxide through an electrochemical process, proves to be highly effective in various applications such as wastewater treatment, green nitrite and nitrate production, and hydrogen gas generation. The team's innovation addresses the environmental challenges posed by ammonia, including harmful effects on aquatic ecosystems and human health. NiOOH-Ni's versatile nature allows it to adjust its reaction pathway based on the voltage applied, enabling the production of nitrite or nitrate as needed. This flexibility makes it a valuable solution for diverse industrial and environmental processes. Professor Zhenguo Huang highlights the superior performance of NiOOH-Ni over traditional catalysts, emphasizing its efficacy at lower voltages and higher currents. Additionally, Associate Professor Andrey Lyalin praises the catalyst's durability and stability, positioning it as a cost-effective alternative to expensive catalysts like platinum. The long-term reliability of NiOOH-Ni opens up possibilities for large-scale industrial use, potentially revolutionizing wastewater treatment practices and clean energy production. This catalyst's development marks a significant advancement in green technology and paves the way for more efficient and sustainable industrial processes.
