Oxygen‐Doped Porous Carbon Nanosheet for Efficient N ₂ Fixation to NH ₃ at Ambient Conditions

Abstract NH 3 is one of the largest‐volume industrial chemicals synthesized in the world. It not only is a kind of important chemical base materials to produce fertilizers, plastics and explosives, but also can serve as a clean energy carrier with high hydrogen content for a sustainable energy supply. N 2 is the most abundant gas in atmosphere, but its inert character caused by the strong triple bond, impedes itself from being converted to NH 3 . In nature, this shortcoming is overcome by biological N 2 fixation utilizing nitrogenase enzymes. Industrially, fixation of N 2 ‐to‐NH 3 prevailingly depends on Haber‐Bosch process using Ru‐ or Fe‐based catalysts, but this process consumes large energy and emits heavy carbon which increases crisis of global warming.
