Abstract
AbstractIn recent years, photoelectrochemical (PEC) sensors have attracted much attention due to their inherent advantages, such as ease of operation, high sensitivity, and structural diversity. Compared with conventional PEC detection methods, self‐illuminated PEC sensors do not require an external light source, which makes them more attractive in terms of instrument miniaturization and simplified operation. Chemiluminescence (CL), a straightforward and efficient excitation source, can be harnessed for PEC sensors. In this review, we provide a summary on the recently reported chemiluminescence‐driven PEC sensors. Initially, we briefly describe the current chemiluminescent systems employed in PEC sensors, including luminol and peroxyoxalate CL systems. Subsequently, the CL‐exciting modes and the design strategies for self‐excited PEC sensors are explored. The subsequent sections of the paper predominantly focus on discussing the applications of such PEC sensors in the detection of various target analytes. Furthermore, future prospects for advancing these PEC sensors are discussed.
