Gongye shui chuli, 2021 利用光催化技术降解氧氟沙星，是处理喹诺酮类抗生素废水的有效途径。通过固相扩散法将TiO2微球(MS-TiO2)负载于沸石上制备MS-TiO2/沸石复合催化剂，采用XRD、SEM、UV-Vis对其进行表征。以模拟太阳光催化降解水中氧氟沙星考察其催化活性。结果表明，当TiO2负载量为35%，煅烧温度为450℃，催化剂投加量为1.5 g/L，废水初始pH为6.5时，光催化氧氟沙星的降解率达到最佳，为95.1%。氧氟沙星光催化降解过程符合一级动力学方程。

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT The development of efficient and stable bifunctional catalysts remains a key challenge for green hydrogen production via electrochemical water splitting. In this study, a bimetallic Mo/Fe‐doped CoP2 nanoleaf array anchored on carbon cloth (Mo, Fe‐CoP2@CC) was synthesized from zeolitic imidazolate framework‐L (ZIF‐L) via an ion‐exchange and low‐

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Photocatalytic molecular oxygen (O2) activation provides a sustainable approach to produce singlet oxygen (1O2) for organic contaminants detoxification. However, the charge carriers‐involved pathway usually suffers from unsatisfactory 1O2 production efficiency owing to energy loss caused by photogenerated hole‐mediated superoxide species (•O2−

Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Converting CO2 to CH4 under mild conditions is a promising strategy for solving environmental and energy problems, but also a challenge. In this work, the low‐temperature CO2 hydrogenation process over Ni/CeO2 catalysts was significantly accelerated by optimizing the H2 dissociation ability of Ni through the size effect, thus A‐Ni/CeO2 with an
