Direct CO₂ capture and conversion to fuels on magnesium nanoparticles under ambient conditions simply using water.

ABSTRACT: Converting CO₂ directly from the air to fuel under ambient conditions is a huge challenge. Thus, there is an urgent need for CO₂ conversion protocols working at room temperature and atmospheric pressure, preferentially without any external energy input. Herein, we employ magnesium (nanoparticles and bulk), an inexpensive and the eighth-most abundant element, to convert CO₂ to methane, methanol and formic acid, using water as the sole hydrogen source. The conversion of CO₂ (pure, as well as directly from the air) took place within a few minutes at 300 K and 1 bar, and no external (thermal, photo, or electric) energy was required. Hydrogen was, however, the predominant product as the reaction of water with magnesium was favored over the reaction of
