Enhancing the quasi-theoretical photocurrent density of ZnO nanorods via a lukewarm hydrothermal method

Anti-reflection enhanced the light harvesting efficiency of a ∼10-μm-long 1D ZnO NRA, which is evidently manifested in the quasi-theoretical photocurrent density that reached ∼0.9 mA cm⁻² for solar photoelectrochemical water splitting.
