Photoelectrocatalytic nitrate reduction offers an opportunity for a lower carbon route to ammonia production but has not been realized due to poor efficiency. Here an efficient modified lead halide perovskite photocathode is coupled to glycerol oxidation anode resulting in a bias-free photocurrent density greater than 20 mA cm−2.
