Commentary on our Recent Work on PEI/TiO2 Hybrid Film as a Hole-Selective Protective Coating for Stable Solar Water Oxidation

Solar water splitting has long captivated researchers, as it offers the potential to produce versatile hydrogen without external energy input. However, this goal remains challenging, as evidenced by the extensive research on the topic since the pioneering work of Honda and Fujishima in 1972. In particular, metal oxide semiconductors like BiVO4 and Fe2O3 have garnered significant attention for solar water oxidation due to their elemental abundance, relatively small bandgap, and perceived stability. Despite considerable advances in enhancing the efficiency of solar water oxidation with these oxide photoelectrodes, their stability under oxidative conditions has proven problematic, dispelling the initial perception that oxide materials would remain stable in such harsh environments.

Researchers have explored various strategies to address these stability issues, finding that modifying oxide photoanodes with inherently stable TiO2 is one of the most effective approaches. However, TiO2, as a naturally n-type semiconductor with a deep-lying valence band, is not ideal for photoanodes since it obstructs hole transport, which is essential for water oxidation. Some studies suggest that ultra-thin, nanometer-scale TiO2 films can enhance stability while allowing hole transport via defect states or tunneling. Nevertheless, it is practically difficult to avoid pinholes in such thin films, which can limit stability. Consequently, thicker TiO2 films are needed as protective coatings, but these tend to be unsuitable for oxide photoanodes due to significant energy-level mismatches.

In this study, Dr. Sanghyun Bae proposed using a hybrid film composed of TiO2 and an amine-rich polymer as a protective coating layer for oxide photoanodes in solar water oxidation. When hybridized, amine-rich polyethyleneimine introduces sufficient defect states even in thicker TiO2 layers, allowing for improvements in both the performance and stability of various oxide semiconductors. Further technical details are available in our paper, which is freely accessible:
- Title: A hole-selective hybrid TiO2 layer for stable and low-cost photoanodes in solar water oxidation
- Citation: Nature Communications, 2024, 15, 9439. - Link: https://t.co/n0uvSOaFkd

Dr. Sanghyun Bae initiated this work during his Ph.D. studies in my group and while visiting Prof. David Tilley’s group at the University of Zurich; he completed it as a postdoctoral researcher in Prof. Tilley's group. I am delighted to have been involved in this excellent work, thanks to Dr. Bae and Prof. Tilley.
