Mechanism and setup of EMF-assisted thermal catalysis

Caption

(a) Ammonia concentration under different temperatures with and without an EMF at 1 MPa. (b) Comparison of ammonia concentration and energy cost for the scale-up experiment at 200 ℃ and 1 MPa with and without the EMF. (c) Adsorption energy of N2 on Fe(110) with and without an EMF (1 V Å-1). Atomic structure of N2 side-on adsorption on the Fe(110) surface with (d) and without (e) an external electric field and N2 end-on adsorption on the Fe(110) surface with (f) and without (g) an external electric field. Gray ball: Fe, blue ball: N. Charge density difference of N2 side-on adsorption with (h)and without (i) an external electric field and N2 end-on adsorption with (j) and without (k) an external electric field. The isosurface value is 0.003 e Å-1The yellow isosurface represents electron accumulation, and cyan denotes electron depletion.
