There is a dire need for selective catalysts that allow us to consistently achieve a desired outcome in a chemical reaction. It is this consistency that allows for more efficient, energy-saving ways of producing fuel. A team of researchers from Tohoku University, the Indian Institute of Technology I ndore, and Dalhousie University have revealed that a Cu14 nanocluster (NC) with just a single exposed Cu site exhibits remarkably high ammonia (NH3) selectivity (~80%) and production rate for the electrochemical nitrate ion reduction reaction. ...read more read less
