Researchers are exploring the use of nanocrystal-nitrogenase biohybrids to reduce energy costs in ammonia production by harnessing light to convert N2 gas to ammonia. By studying electron delivery efficiency and hole scavenging in the CdS:MoFe complex, they aim to optimize the process and potentially lower energy costs. This innovative technology could lead to localized production near agricultural sites, reducing transportation costs and offering applications in fuel, feedstock, and energy storage. The research, highlighted by the U.S. Department of Energy's Office of Science Basic Energy Sciences program, provides valuable insights into biological nitrogen fixation and electron transfer pathways, with implications for sustainable climate solutions.
