Quantum dots (QDs) function as photon sensitizers in photoelectrocatalysis (PEC),
enhancing the ability of bulk materials to harness a broad spectrum of photon
energy. Through precise engineering, QDs facilitate the development of advanced
strategies to synthesize high-performance photoelectrodes that improve the
efficiency of light-driven technologies. This review highlights valuable insights
in integrating QDs into PEC systems, focusing on heterojunction-mediated charge
transfer. We explore their unique optoelectronic properties, the enhancement of
conventional photoanodes and photocathodes, and strategies to optimize
interfacial charge transfer dynamics for efficient photon-to-energy conversion.
Finally, we discuss the advantages, limitations, and future prospects of QD-based
PEC technology.
