nitrogen

Anthropogenic nutrient enrichment of the global environment has been proceeding for many decades. Nitrogen deposition in particular leads to higher ecosystem productivity at the expense of biodiversity. In a global experiment spanning 45…

Shuttling protons in ammonia synthesisAn electrochemical route to ammonia could substantially lower the greenhouse gas emissions associated with the current thermal Haber-Bosch process. One relatively promising option under study involves…

SummaryThe Haber-Bosch process converts nitrogen (N2) and hydrogen (H2) into ammonia (NH3) over iron-based catalysts. Today, 50% of global agriculture uses Haber-Bosch NH3 in fertilizer. Efficient synthesis requires enormous energy to…
