Published: April 2, 2024

Abstract Flat panel reactors, coated with photocatalytic materials, offer a sustainable approach for the commercial production of hydrogen (H 2 ) zero carbon footprint. Despite this, achieving high solar‐to‐hydrogen (STH) conversion efficiency these reactors is still significant challenge due to low utilization solar light and rapid charge recombination. Herein, hybrid gold nano‐islands (HGNIs) are developed on transparent glass support improve STH efficiency. Plasmonic HGNIs grown an in‐house active sheet composed sodium aluminum phosphosilicate oxide (H‐glass) using thermal dewetting method at 550 °C under ambient atmosphere. various oxidation states (Au 0 , Au + − multiple interfaces obtained diffusion elements from structure, which also facilitates lifetime hot electron be ≈2.94 ps. H‐glass‐supported demonstrate 0.6%, without any sacrificial agents, via water dissociation. This study unveils specific role in facilitating light‐driven chemical conversions, offering new avenues development high‐performance photocatalysts reactions large‐scale applications.

CdSe Quantum Dots Supported on Sb₂S₃ Nanorods as S-Scheme Heterojunction Photoanode in Photoelectrochemical Cells

ACS Applied Nano Materials, Journal Year: 2024, Volume and Issue: 7(20), P. 24213 - 24223

Published: Oct. 7, 2024

The narrow bandgap semiconductor Sb2S3 has been extensively utilized in solar cells for its impressive light absorption coefficient and carrier mobility. However, a large number of deep energy defects provide recombination sites that limit photoelectrochemical (PEC) performance. In this study, nanorods (NRs) CdSe quantum dots (QDs) were successfully prepared, Sb2S3/CdSe-annealed quasi-one-dimensional heterojunction photoanodes with the S-scheme constructed. composite photoelectrode achieves 12 times increase photocurrent density compared to 0.4 mA cm–2 photoelectrode. Overall, synergistic effect [hk1]-oriented NRs promotes transport, achieving spatial separation photogenerated carriers efficiently weakening electron–hole pair.
