An electrode includes an electrically conductive substrate with a coating containing boron-doped diamond (BDD) nanoparticles. Fabricating the electrode can include dispersing BDD nanoparticles in a solvent to yield a suspension, coating a conductive substrate with the suspension, and drying the suspension to yield the electrode. In some cases, fabricating the electrode includes combining BDD nanoparticles with a polymeric resin precursor to yield a mixture including a metal oxide, coating a conductive substrate with the mixture to yield a coated substrate, and calcining the coated substrate to yield a metal oxide coating including BDD nanoparticles. In certain cases, fabricating the electrode includes combining powdered activated carbon with polymeric linkers to yield a polymeric precursor solution, combining BDD nanoparticles with the polymeric precursor solution to yield a mixture, coating a conductive substrate with the mixture to yield a coated substrate, and crosslinking the polymeric linkers to yield the electrode.
