“…Two characteristic peaks ( Figure 3 c) at 159.7 eV and 165.0 eV were ascribed to Bi 4f 5/2 and Bi 4f 7/2, indicating the existence of Bi 3+ in BGA-4 [ 30 ]. As shown in Figure 3 d, the O 1s core-level spectrum of BGA-4 could be mainly divided into two peaks at about 531.5 and 533.7 eV, corresponding to the Cl–O and C–O bonds in XPS [ 31 ]. The high-resolution Cl 2p spectra ( Figure 3 e) including two obvious characteristic peaks at 198.6 eV and 200.2 eV were ascribed to Cl 2p 1/2 and Cl 2p 3/2, indicating the existence of BiOCl in BGA-4.…”

“…The results indicated that some of the oxygen-containing groups on GO were retained in the process of BGA-4 synthesis, which may be beneficial for the activation of PDS.

BiOCl/graphene aerogel graphene (BGA) was successfully obtained by in situ hydrothermal synthesis, and the chemical, structural, morphological, and photocatalytic properties were systematically characterized. BGA with the doping amount of BiOCl at 20% (BGA-4) exhibited the optimal activation efficiency for persulfate (PDS) on the degradation of methyl orange (MO) under simulated sunlight (SSL) illumination as compared to the pure graphene (GA) and aerogel composites with different BiOCl content. The influence of various reaction parameters on the MO removal efficiency, such as the reaction system, catalyst activator dose, PDS concentration, BiOCl doping amount, and the initial pH of the solution, was investigated. Under optimum conditions, the catalytic efficiency of BiOCl-doped GA with the mass ratio of 20% (BGA-4) was 5.61 times that of GA. The strengthening effect of BGA-4 benefited from the synergistic effect of 1O2, O2·− and the generation and rapid electron transfer of photo-induced electron (e−) in the BGA-4/SSL/PDS system. Considering the superior stability and recyclability of BGA-4, the BGA-4/SSL/PDS system exhibits great potential in actual wastewater treatment.

The NiNiO/GR‐TiO2 magnetic hollow rod composites based on lignocellulose was prepared via electroless Ni and sol‐gel method to effectively solve that the composites were difficult to recycle and reuse. Rapid degradation of organic dyes was conducted. The element distribution, surface morphology, and functional groups were characterized via SEM, TEM, LSCM and FT‐IR, respectively. The structure was characterized by XRD and XPS. The photocatalytic properties were tested via TU‐1950 UV spectrophotometer. The EDS demonstrated the increase of S and N elements and FT‐IR results, indicating that methylene blue has been degraded by ring‐opening reaction. The results showed that the surface elements of the hollow rod structure were evenly distributed. The composite catalytic efficiency could reached 57.65 % and catalytic material prepared in vacuum was 93.34 % when the dosage of graphene was 50 mg. The composite materials photocatalytic system with addition of 20 mL EDTA could greatly improve the catalytic efficiency, which was up to 97.43 %.
