The surface properties of oxidic supports and their interaction with the supported metals play critical roles in governing the catalytic activities of oxide‐supported metal *** metals are supported on reducible oxides,dynamic surface reconstruction phenomena,including strong metal–support interaction(SMSI)and oxygen vacancy formation,complicate the determination of the structural–functional relationship at the active ***,we performed a systematic investigation of the dynamic behavior of Au nanocatalysts supported on flame‐synthesized TiO_(2),which takes predominantly a rutile phase,using CO oxidation above room temperature as a probe *** analysis conclusively elucidated a negative correlation between the catalytic activity of Au/TiO_(2) and the oxygen vacancy at the Au/TiO_(2) *** the reversible formation and retracting of SMSI overlayers have been ubiquitously observed on Au/TiO_(2) samples,the catalytic consequence of SMSI remains *** functional theory suggests that the electron transfer from TiO_(2) to Au is correlated to the presence of the interfacial oxygen vacancies,retarding the catalytic activation of CO oxidation.

针对光催化反应过程中光生电子与空穴复合率高、可见光谱吸收利用率低等问题,利用水热法合成具有较窄带隙的钙钛矿型铁酸铋(BiFeO_(3))。研究结果表明:在超声与光照的协同作用下,反应原料中NaOH浓度为8 mol/L时合成的BiFeO_(3)样品的性能最佳,在15 min内对靛蓝胭脂红染料的降解率达97.6%,拟合得到的一级反应速率常数为0.2036 min^(−1),其原因是其较窄的能带隙导致电子跃迁能量阈值较低。自由基捕获实验验证了压电光催化的反应机理,并验证了BiFeO_(3)产生的压电场促进光催化反应进程的耦合效应。
