Photoreduction properties of novel Z-scheme structured Sr0.8La0.2(Ti1−δ4+Tiδ3+)O3/Bi2MoO6 composites for the removal of Cr(vi)

“…The peak at 529.23 eV could be attributed to the lattice oxygen of SrTiO 3 , while the middle peak at 530.75 eV could be attributed to O v in LSTO. 46 The peak at 533.29 eV is usually assigned to the loosely bound oxygen on the LSTO surface. 47 BMO exhibits two peaks at 529.80 eV and 530.49 eV, which are ascribed to the Bi–O and Mo–O bonds, respectively, of Bi 2 MoO 6 .…”

“…In Fig. 4 46 The peak at 533.29 eV is usually assigned to the loosely bound oxygen on the LSTO surface. 47 In our sample LSTBM7, there are a few surface hydroxyl groups.…”

SrTiO3–TiO2 Heterostructured Nanotube Arrays for Ultrafast Ethanol Sensing

“…Conventional semiconducting metal oxides such as TiO 2 , − In 2 O 3 , , CO 3 O 4 , CuO, Fe 2 O 3 , In 2 O 3 , SnO 2 , , and WO 3 , , have widely been used for the detection of volatile organic compounds (VOCs). The fascinating physical and chemical properties such as stability, large band gap, high surface-to-volume ratio, the possibility of synthesizing different nanoforms, biodegradability, nontoxicity, and low cost of TiO 2 among other metal oxides make it the most promising gas/VOC sensing material. , Many researchers introduced a variety of TiO 2 morphologies including one-dimensional (1D), , two-dimensional (2D), and three-dimensional (3D).…”

“…Among various volatile organic compounds, ethanol is a widely known VOC used in industries and laboratories, monitoring drunken driving, and so forth . Ethanol as a biomarker for pulmonary disease and liver damage gathered more interest from the researchers for efficient and real-time detection for breath analysis application. , Trabelsi et al studied the ethanol sensing properties of oxygen vacancy-modulated SrTiO 3‑δ compounds and revealed that the number of oxygen vacancies can be easily modulated in SrTiO 3 and can significantly improve its ethanol sensing performance . In a different study, Zhi Meng et al reported an ethanol sensor based on p-type LaRhO 3 film which was epitaxially grown on a SrTiO 3 (110) substrate as a high-quality sensing channel with good response (8.4/50 ppm ethanol) and fast response/recovery speed (54 s/23 s) at 275 °C .…”

The studies reveal that the high sensitivity and fast response/recovery time of the SrTiO 3 -based ethanol sensor could be due to the high defect density (oxygen vacancy) and high carrier mobility in the single-crystalline heterostructures of SrTiO 3 .…”
