Here, we report a family of Prussian blue analogue-derived Cu/Co/Fe oxide heterostructures as compositionally programmable hybrid materials for high-rate nitrate-to-ammonia electrosynthesis. By tuning the Cu/Co ratio, the heterointerface coupling and associated d-band-center modulation can be rationally regulated to optimize *NO_x adsorption and sequential hydrogenation.

Surface characterizations including wetting behavior, FTIR, and SEM–EDX analysis were used to confirm the effectiveness of the modification techniques. The mechanical performance of SHCC reinforced with the three types of fibers was evaluated using uniaxial tensile tests.
