Hexaamminecobalt(III) chloride underwent reaction in an aqueous AgNO₃ solution containing a buffer base (pH 7–9), producing insoluble AgCl that showed no visible light photoresponse. The resultant molecular Co(III)/AgCl system showed water oxidation activity under visible light (λ > 400 nm), approximately five times greater than that of a previously reported CoO_x/anatase-TiO₂ photocatalyst.

用于可见光水氧化的钴（III）/氯化银光催化剂的原位形成

氯化六氨合钴 ( III ) 在含有缓冲碱 (pH 7-9) 的AgNO ₃水溶液中发生反应，产生不溶性 AgCl，没有可见光响应。所得分子 Co( III )/AgCl 体系在可见光 ( λ > 400 nm)下显示出水氧化活性，比先前报道的 CoO _x /锐钛矿-TiO ₂光催化剂高约五倍。
