Abstract

Herein, a novel photoelectrochemical (PEC) sensing platform was developed based on target-induced switching from indirect Z-scheme NPC-ZnO/Au/CdS to direct Z-scheme CdS/hemin systems accompanied by the photocurrent-polarity switching from cathodic to anodic photocurrents. The developed PEC sensor exhibited excellent selectivity and high sensitivity.
