Plasmonic Ag-TiO2−x nanocomposites for the photocatalytic removal of NO under visible light with high selectivity: The role of oxygen vacancies

Efficient Degradation of Phenol and 4‐Nitrophenol by Surface Oxygen Vacancies and Plasmonic Silver Co‐Modified Bi2MoO6 Photocatalysts

“…Recent results revealed that higher intensity means ah igher rate of photogenerated electron-and-hole recombination. [37,58,59] This result is in good accordance with TEM, EPR,R aman, and UV/Vis spectral analyses. This effect is furtherc onfirmed by the time-resolved photoluminescence (TR-PL) analysis.…”

“…Moreover,ablueshift in the PL emission peak of 2%A/BMO-SOVs-375 compared with that of BMO was observed, and this could be mainly attributed to the recombination of the photogenerated holes with the single-electron oxygen vacancy. [37,58,59] This result is in good accordance with TEM, EPR,R aman, and UV/Vis spectral analyses.…”

“…[34] To achievea no ptimal photocatalytic activity,t he combination of the two above-mentioned strategiesi sa pplied to the preparation of ah eterostructured photocatalyst. [35][36][37][38] To our knowledge,s uch ad esign strategy for visible-light-driven Bi 2 MoO 6 -based photocatalytic materials hass eldom been reported. Here, inspiredb yt he above impressive advances, we have rationally designed and successfully fabricated an ew oxygen-vacancy-rich Ag/Bi 2 MoO 6 photocatalyst with ah igh visible-light-driven photocatalytic activity by af acile solvothermal methodc ombined with an impregnation-calcination approach.P henol and 4-nitrophenol (4-NP) were used as organic pollutantst oa ssess the photocatalytic activities of the prepared samples.…”

“…[33] The obtained Ag/g-C 3 N 4 composite exhibited highly photocatalytic activities toward aerobic oxidative amidation of aromatic aldehydes under visible-light irradiation owing to the strong LSPR effect of Ag.

Annealing temperature induced improved crystallinity of YSZ thin film

“…The existence of high Zr 4+ and Y 3+ contents led to the adsorption of more atmorpheric O 2 , leading to the formation of O 2− (oxygen loss or depletion). Thus, an exceptionally low oxygen dissolution in YSZTFs was recodred [46]. Figure 7 presents TEM images, lattice fringe and SAED pattern of YSZTF annealed at 400 and 500°C.…”
