A team of Australian and Japanese scientists has collaborated to develop a groundbreaking catalyst called NiOOH-Ni, designed to enhance the efficiency of ammonia conversion. This innovation has the potential to revolutionize various applications, including wastewater treatment, green nitrite and nitrate production, and hydrogen generation. The catalyst was created by combining nickel with nickel oxyhydroxide through an electrochemical process. Despite its irregular structure, NiOOH-Ni significantly boosts ammonia conversion efficiency, operating at lower voltages and higher currents than conventional catalysts. This design flexibility enables the catalyst to produce nitrite or nitrate based on the required voltage, offering versatility in applications. Professor Zhenguo Huang from the University of Technology Sydney highlights that NiOOH-Ni can effectively convert ammonia into less harmful substances at lower voltages, while higher voltages enable the production of nitrate. Additionally, the catalyst can generate hydrogen gas, serving as a clean fuel source. Its durability and stability even after multiple uses make it a cost-effective alternative to expensive traditional catalysts like platinum. Associate Professor Andrey Lyalin from Hokkaido University emphasizes the catalyst's reliability for large-scale industrial use, potentially reshaping how industries manage wastewater and produce clean energy. The study's publication in Advanced Energy Materials marks a significant step towards sustainable environmental practices and efficient energy production.
