Synthesis of Ag3PO4/G-C3N4 Composite with Enhanced Photocatalytic Performance for the Photodegradation of Diclofenac under Visible Light Irradiation

“…The sharp peak centered at 808 cm −1 indicated a characteristic breathing mode of the triazine units, and verified that the prepared photocatalyst was a g-C 3 N 4 or g-C 3 N 4 -based catalyst [36][37][38]. For Ag 3 PO 4 , the observed strong peak at 546 cm −1 was related to the O=P-O bending vibration, while the peak at 860 cm −1 was assigned to the symmetric and asymmetric vibration modes of P-O-P [39]. All of the characteristic peaks of g-C 3 N 4 and Ag 3 PO 4 could be observed in the spectra of Ag 3 PO 4 /g-C 3 N 4 composites, and the intensity of the peaks at 546 cm −1 and 860 cm −1 rose with the increase of Ag 3 PO 4 content.…”

Ag3PO4/BiPO4 p–n heterojunction nanocomposite prepared in room-temperature ionic liquid medium with improved photocatalytic activity

“…In the spectra of the prepared samples, the broad absorption peaks appearing at about 3300-3600 cm À 1 and 1658 cm À 1 are attributed to the O-H stretching and H-O-H bending vibrations on the catalyst surface and the surface adsorbed water, respectively. Also, the two peaks around 1015 cm À 1 and 560 cm À 1 are assigned to the P-O stretching vibrations of PO 3 À 4 groups [24]. More specifically, the characteristic peaks of both Ag 3 PO 4 and BiPO 4 were all presented in the spectra of Ag 3 PO 4 /BiPO 4 hybrid composite photocatalysts, testifying that the structure of Ag 3 PO 4 and BiPO 4 had been unchanged upon the p-n heterojunction formation between Ag 3 PO 4 and BiPO 4 semiconductors.…”

One-pot synthesis of ultra-small cerium oxide nanodots exhibiting multi-colored fluorescence

“…The fascination with nanotechnology emerges from the unique physiochemical properties due to the reduction in size [1]. Small nanocrystals often show unusual size-and shape-dependent optical properties as they confine their electrons resulting in quantum effects manifested as novel optical properties.…”
