In-situ constructed indirect Z-type heterojunction by plasma Bi and BiO2-X–Bi2O2CO3 co-modified with BiOCl@Bi–MOF for enhanced photocatalytic efficiency toward antibiotics

H2S-Reactivating Antitumor Immune Response after Microwave Thermal Therapy for Long-Term Tumor Suppression

“…Then, element mapping (Figure 1d) and energy dispersive X-ray spectra (EDS) characterization (Figure S2) confirmed the presence of Bi, N, O, and S elements in BMCPH, and X-ray photoelectron spectroscopy (XPS) survey spectra displayed the Bi 4f 7/2 and Bi 4f 5/2 orbitals, demonstrating that the contained Bi was +3 valent (Figure S3). 41 The zeta potential changing from −12.5 mV of BM to 31.2 mV of BMC, 15.6 mV of BMCP, and −22.8 mV of BMCPH also indicated the continuous surface modification (Figure 1e). To further assess the coupled L-Cys, Fourier transform infrared (FTIR) spectroscopy was utilized to characterize the characteristic peak, and −SH in L-Cys at about 2560 cm −1 was consistent with that in BMC (Figure 1f).…”

Bi2O2CO3 Nanosheet Composites with Bi-Based Metal–Organic Frameworks for Photocatalytic H2O2 Production

“…As depicted in Figure S2, the prepared Bi-MOF exhibits three crystalline phases with diffraction peaks at 11.6, 14.9, 20.4, and 24.1°, corresponding to CCDC: 1404669. The diffraction peaks at 12.9 and 17.8° correspond to CCDC: 1976709 . The remaining diffraction peaks can be attributed to CCDC: 1426169 .…”

“…The diffraction peaks at 12.9 and 17.8°c orrespond to CCDC: 1976709. 31 The remaining diffraction peaks can be attributed to CCDC: 1426169. 27 After adding H 3 BTC to Bi 2 O 2 CO 3 , the peaks of Bi-MOF appeared, accompanied by the weakening Bi 2 O 2 CO 3 phase in B/BF-750 and almost disappeared Bi 2 O 2 CO 3 phase in B/BF-900.…”

“…40 The E VB of Bi 2 O 2 CO 3 and Bi-MOF can be calculated to 2.89 and 3.85 V, respectively, according to the equation (E VB = E CB + E g ). 41 The band diagrams (Figure 5e) indicate that Bi 2 O 2 CO 3 possesses enough reducing power for O 2 reduction, which is used to improve the H 2 O 2 evolution rate. 42 The CB potential of Bi 2 O 2 CO 3 is more positive than the reaction potential of indirect ORR, and B/BF-750 is thermodynamically insufficient…”

Synthesis of Dual p–n Heterojunction of Ni/Mn-MOF-74/CdS@Co3O4 Photocatalyst as a Photoassisted Fenton-like Catalyst for Removal of Tetracycline Hydrochloride

“…One effective method was the construction of interface heterojunctions, which improved the efficiency of separating photogenerated e – and h + . The discovery of Z-type heterojunctions had addressed the challenges faced by single photocatalysts with low quantum efficiency and traditional heterojunctions with insufficient redox abilities. − By selectively consuming or recombining the photogenerated e – /h + on specific conduction and valence bands, the Z-type heterojunction retained e – and h + with strong redox abilities on both ends . The p–n junction was formed by the contact between a p-type semiconductor and an n-type semiconductor, and a built-in electric field from the n-type semiconductor to the p-type semiconductor is generated at the interface between the two.…”
