NH3 synthesis heavily depends on the energy-intensive Haber–Bosch process, which produces serious carbon emission. Electrocatalytic N2 reduction emerges as an environmentally benign process for sustainable artificial N2 fixation but requires efficient, stable and selective catalysts for the N2 reduction reac The structural studies on the Cr2O3-PbO-Fe2O3-P2O5 glasses showed that the compositions containing up to 4 mol% Cr2O3 formed fully amorphous samples while compositions containing 8 and 10 mol% Cr2O3 partially crystallized during cooling to Fe7(PO4)6, Fe2Pb3(PO4)4 and Cr2Pb3(PO4)4.
