Abstract
Photoelectrochemical (PEC) water splitting is a promising strategy for green hydrogen (H2) production with the potential to address global clean energy and associated environmental challenges. Due to the remarkable ability to capture broad-range light, high absorption coefficient, and the possibility of multi-exciton generation, colloidal quantum dots (QDs) are considered key building blocks for developing high-performing solar-driven H2 production technologies. This review provides a concise overview of the recent developments in eco-friendly QDs-based PEC H2 production. It outlines various methods for synthesizing eco-friendly QDs and provides a detailed discussion on the structural engineering of eco-friendly QDs and how the different strategies impact the structure–property relationships. Furthermore, the effect of optimizing charge dynamics and band structures on the performance of eco-friendly QDs-based PEC systems is discussed in detail. Finally, the challenges and prospects of this field are examined to realize their cost-effective potential and enter large-scale deployment for solar-driven H2 production.
