了解NO的光催化转化机理对于制定有效和实用的室内空气污染控制策略至关重要。本文以柠檬酸铋和五水四氯化锡为前驱体，采用水热法合成了纳米Bi 2Sn 2 O 7，并对其光催化去除NO的机理进行了系统的研究。进行各种表征以研究所制备的样品的物理化学性质。通过模拟太阳光照射下连续反应器中NO的光催化降解，评价了所制备的Bi 2Sn 2 O 7样品的性能。合成12 h的Bi 2Sn 2 O 7样品（BSO-12）的NO去除率为37%，远高于合成24 h的Bi 2Sn 2 O 7样品（BSO-24）和合成36 h的Bi 2Sn 2 O 7样品（BSO-36）。光电流测试和电化学阻抗谱（EIS）结果表明，BSO-12样品具有较好的电化学性能。
Understanding the photocatalytic conversion mechanism of NO is crucial to develop an effective and practical strategy for indoor air pollution control. In this study, we systematically investigated the photocatalytic removal mechanism of NO over nanocrystalline Bi2Sn2O7, which was successfully synthesized via hydrothermal method using bismuth citrate and stannic chloride pentahydrate as precursors for the first time. Various characterizations were carried out to study the physicochemical properties of the as-prepared samples. The performance of the as-prepared Bi2Sn2O7 samples was evaluated by the photocatalytic degradation of NO in a continuous reactor under simulated solar light irradiation. The NO removal rate over the Bi2Sn2O7 sample synthesized for 12 h (BSO-12) was 37%, which was much higher than those of Bi2Sn2O7 samples synthesized for 24 h (BSO-24) and 36 h (BSO-36). Results from photocurrent tests and electrochemical impedance spectroscopy (EIS) demonstrated that the BSO-12 sample presents much ...
