Stable and efficient photoelectrochemical water splitting has been achieved using a BaTaO2N photoanode decorated with CoO microflowers. The CoO microflowers effectively collect holes from BaTaO2N which kinetically protects BaTaO2N against photocorrosion. A Faraday efficiency of almost unity (99.2%) has been recorded for O2 evolution reactions. The tips of the CoO microflowers are the most active sites for water oxidation reactions.
使用装饰有CoO微花的BaTaO₂N光阳极实现了稳定且高效的光电化学水分解。CoO微花有效地从BaTaO₂N收集空穴，从而在动力学上保护BaTaO₂N免受光腐蚀。对于析氧反应，记录到的法拉第效率几乎达到了100%（99.2%）。CoO微花的尖端是水氧化反应最活跃的位点。
