“…47 As a result, when pH = 7, CoIS-2 has the best photocatalytic degradation activity. Similar findings were also reported by Zhou et al 48 The TOC analysis was employed to estimate the TCH mineralization efficiency of CoIS-2 under visible-light illumination (Figure 5e). The TOC removal efficiency of TCH reached 63.9% after 60 min of irradiation, which is slightly lower than its photodegradation efficiency.…”

Rational design of a hierarchical core−shell structured photocatalyst is crucial for enhancing the separation and transport efficiency of photogenerated carriers, thereby improving the photocatalytic degradation efficiency. In this study, hollow polyhedral CoS x was first synthesized by utilizing dodecahedral Co-based metal−organic framework (ZIF-67) as a Co source and template, followed by introducing In and S species to fabricate hierarchical core−shell In 2 S 3 /CoS x composites. The resulting In 2 S 3 / CoS x porous hollow heterostructured composites exhibited an accelerated interfacial carrier transfer ratio and enhanced photocatalytic removal performance of tetracycline hydrochloride (TCH). Among them, the optimized sample In 2 S 3 /CoS x -2 (CoIS-2) demonstrated the highest TCH removal rate of 0.0324 min −1 , which was 22.8 times higher than that of pristine CoS x and 5.7 times higher than that of pure In 2 S 3 , respectively. Moreover, its apparent quantum efficiency reached 4.66% at 420 nm. Electron spin resonance analysis and active substance capture experiments confirmed that superoxide radical ( • O 2 − ) played a predominant role in the reaction system. Furthermore, we investigated the dynamics of photoinduced carriers through a series of photoelectric tests combined with density functional theory calculations. This study provides valuable insights into controllable construction of metal− organic framework-based materials with high photocatalytic degradation efficiency and stability.

“…However, compared to all samples, Ag 2 O had a higher absorbance in the visible light region (Figure a). Although Ag 2 O had higher visible light absorption, the higher electron and hole recombination rates limit its photocatalytic activities . According to the Kubelka–Munk function, the optical band gap values for ZnO, CZ-2, and CZA-15 samples were calculated .…”

Herein, Cellulose-templated Zn 1−X Cu X O/Ag 2 O nanocomposites were prepared using biological renewable cellulose extracted from water hyacinth (Eichhornia crassipes). Cellulose-templated Cu-doped ZnO catalysts with different amounts of Cu as the dopants (1, 2, 3, and 4%) were prepared and denoted CZ-1, CZ-2, CZ-3, and CZ-4, respectively, for simplicity. The prepared catalysts were tested for the degradation of methylene blue (MB), and 2% Cu-doped ZnO (CZ-2) showed the best catalytic performance (82%), while the pure ZnO, CZ-1, CZ-3, and CZ-4 catalysts exhibited MB dye degradation efficiencies of 54, 63, 65, and 60%, respectively. The best catalyst (CZ-2) was chosen to further improve the degradation efficiency. Different amounts of AgNO 3 (10, 15, 30, and 45 mg) were used for the deposition of Ag 2 O on the surface of CZ-2 and denoted CZA-10, CZA-15, CZA-30, and CZA-45, respectively. Among the composite catalysts, CZA-15 showed remarkable degradation efficiency and degraded 94% of MB, while the CZA-10, CZA-30, and CZA-45 catalysts showed 90, 81, and 79% degradation efficiencies, respectively, under visible light within 100 min of irradiation. The enhanced catalytic performance could be due to the smaller particle size, the higher electron and hole separation and charge transfer efficiencies, and the lower agglomeration in the composite catalyst system. The results also demonstrated that the Cu-doped ZnO prepared with cellulose as a template, followed by the optimum amount of Ag 2 O deposition, could have promising applications in the degradation of organic pollutants.

“…Hexagonal barium ferrite (BaFe 12 O 19 , BFO) is a kind of strong magnetic material that not only has strong magnetic properties but also has a wide range of applications in the field of photocatalytic degradation of dyes and other pollutants. 37–46 A CAO/MS/BFO magnetic photocatalyst that is coupled with CAO, MS, and BFO can effectively resolve the difficult recovery and improve the photocatalytic activity of CAO/MS photocatalyst due to the Z-scheme heterojunctions formed by introducing BFO to a type I CAO/MS photocatalyst. It is of great significance to develop new synthesis routes to synthesize the CAO/MS/BFO magnetic photocatalysts and study their photocatalytic activities.…”
