Low-cost graphene sponge electrodes were functionalized with two-dimensional (2D) materials, i.e., borophene and hexagonal boron nitride (hBN), using a one-step, hydrothermal self-assembly method. Borophene hBN-modified anode N-doped cathode employed for electrochemical degradation of model persistent contaminants emerging concern in one-pass, flow through mode, low-conductivity supporting elec...
