Construction of dual Z-scheme UNiMOF/BiVO4/S-C3N4 photocatalyst for visible-light photocatalytic tetracycline degradation and Cr(VI) reduction

Preparation of S-C3N4/AgCdS Z-Scheme Heterojunction Photocatalyst and Its Effectively Improved Photocatalytic Performance

“…Figure 3e shows the S 2p core-level XPS spectrum, where the characteristic binding energy peaks at 161.53 eV and 162.73 eV are assigned to attributed to S 2− in CdS [34]. In Figure 3f, the characteristic binding energy peaks at 398.87 eV, 399.37 eV, and 401.01 eV and corresponds to sp2 nitrogen, sp3 tertiary nitrogen N-(C)3, and amino (C-N-H) in the triazine ring (C-N=C), respectively [35,36]. The optical absorption performance of the prepared photocatalysts was further analyzed by testing the UV-visible absorption spectra, and the results are shown in Figure 4.…”

Enhanced photocatalytic removal of U(vi) from water using tea waste biochar/g-C3N4/MoS2 Z-scheme composite: synthesis, performance, and mechanistic insights

“…39 Among them, the addition of CO 3 2− decreased the removal efficiency of U( vi ) by approximately 19%, which may be related to the increase in the solution pH due to the addition of CO 3 . 2–40 To summarize, the coexisting metal ions and anions have a minor impact on the photoreduction of U( vi ), even when their concentration is 10 times higher than that of U( vi ), indicating little effect on the removal efficiency of U( vi ). Therefore, it is confirmed that 10%BgM has high anti-interference ability for the removal of U( vi ).…”

Montmorillonite helps BiOCl photodegradation of antibiotics

“…60 Then, the acylamino group was cleaved and further cleaved and oxidized to form P14 ( m / z = 338) and P15 ( m / z = 195) through ring opening. 61 Finally, these intermediates could be mineralized to CO 2 and H 2 O.…”
