A novel double anion layered photocatalyst Pb4(BO3)2SO4 with enhanced photocatalytic performance for antibiotic degradation

Highly effective ruthenium-doped mesoporous Ti1−xRuxO2−y crystals for photocatalytic tetracycline degradation

“…S9, ESI †). Ti 0.95 Ru 0.05 O 2Ày shows a 98.74% degradation efficiency of TC within 50 min, which is better than the reported state-of-the-art oxide-based photocatalysts [24][25][26][27][28][29][30][31][32][33] due to the synergetic effect of the improved photon absorption, charge separation/transportation, and the formation of more photoactive centers (Table S3, ESI †). Fig.…”

“…Recently, photocatalytic degradation has received increased attention due to its effective degradation efficiency without the involvement of secondary pollution, low energy consumption and cost, and ease of operation. [18][19][20][21][22][23] Several metal oxides, such as Bi 2 WO 6 , 24 NaTaO 3 @WO 3 , 25 Sb 2 O 3 , 26 g-C 3 N 4 / LaCoO 3 , 27 Pb 4 (BO 3 ) 2 SO 4 , 28 ZnFe 2 O 4 , 29 and TiO 2 , [30][31][32][33] have been developed to degrade tetracycline hydrochloride (TC) through photocatalysis. Among them, TiO 2 with high photocatalytic activity has been intensively investigated.…”

Rational Modulation of Effective Mass Near Band Edge of Li2SnO3 to Increase Photogenerated Carrier Separation Ratio and Photocatalytic Performance

“…Figure a shows the total survey scan XPS spectrum of Li 2 Sn 1– x M x O 3 (M = Pb, Ge; x = 0, 0.10), all observed elements reflected the compositions of the nominal compounds. The high-resolution Pb 4f spectrum (Figure b) could be fitted into two peaks with 138.68 and 143.53 eV, corresponding to Pb 4f 7/2 and 4f 5/2 , respectively, which are characteristic of Pb 4+ . The Ge 3d peak (Figure c) located at 32.65 eV is consistent with the binding energy of Ge–O chemical bonds, which can be assigned to Ge 4+ .…”

Identification and Safety Evaluation of Ochratoxin A Transformation Product in Rapeseed Oil Refining Process

“…However, the LC 50 value of OP-OTA to fathead minnow was still as low as 0.58 mg/L, which implies the strong acute toxicity of OP-OTA. The reason is that the chemical compound with fathead minnow LC 50 value less than 1 mg/L is defined as the “very toxic” grade of chemicals. , OP-OTA also exhibited certain developmental toxicity and bioaccumulation factor, although they were both weaker than those of OTA (lower predicted values). In summary, compared to previously reported OTA derivatives (Table S4), the OP-OTA molecule has strong toxicity, especially nephrotoxicity, according to the experimental data and predicted results.…”
