  • Direct CO2 capture and conversion to fuels on magnesium

    Converting CO 2 directly from the air to fuel under ambient conditions is a huge challenge. Thus there is an urgent need for CO 2 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 CO 2 to methane
