During the past decades, it has remained an open question on whether an artificial particulate photocatalyst can achieve a comparable external quantum efficiency (EQE) of overall water splitting (OWS) as that of natural photosynthesis. Now the answer to this question becomes affirmative. In the Volume 581 of Nature, Domen and co-workers reported an OWS system with an EQE of over 95% at the irradiation region of 350–360 nm on the Rh/Cr₂O₃/CoOOH-loaded SrTiO₃:Al particulate photocatalyst and gave the detailed explanations for this quantum jump.

生物极限附近的人工光合作用

在过去的几十年中，关于人造颗粒光催化剂能否实现与自然光合作用的总水分解（OWS）相当的外部量子效率（EQE），仍然是一个悬而未决的问题。现在，这个问题的答案是肯定的。在《自然》杂志的第581卷中，Domen及其同事报道了在负载Rh / Cr ₂ O ₃ / CoOOH的SrTiO ₃：Al颗粒光催化剂上，在350-360 nm的照射范围内EQE超过95％的OWS系统。并给出了有关该量子跃迁的详细解释。
