英文摘要	Herein, we have demonstrated that the plasma-exfoliation of CoOOH nanolayers (~8 nm) into an ultrathin structure (~2 nm) could significantly improve the PEC activities of BiVO₄ photoanodes. A photocurrent density of 4.9 mA cm^-² and a charge separation efficiency of 89% have been achieved at 1.23 V_RHE under AM 1.5G illumination, which are more than two-fold higher than those of pristine CoOOH/BiVO₄ photoanodes.
