“…Moreover, some intermediate peaks appeared with the time going (Figure S5), which indicated that bisphenol A was gradually decomposed under the attack of generated radicals. 28 Meanwhile, the removal rate of carbamazepine over the BMFe-4 catalyst reached approximately 67% after 80 min (Figure 2f). The degradation efficiency also significantly improved compared with pure BiOI and MIL-53(Fe).…”

Heterojunction catalysts have drawn increasing interest for the visible light-driven Fenton reaction and bring tremendous opportunities for environmental remediation. Herein, a BiOI/MIL-53(Fe) Z-scheme heterojunction (named BMFe) was synthesized for the first time via a facile strategy. Compared with pristine BiOI and MIL-53(Fe) catalysts, the two-dimensional/three-dimensional (2D/3D) heterojunction catalyst manifested remarkable catalytic performance toward degradation of phenol, bisphenol A, methylene blue, and carbamazepine, which is attributed mainly to the interfacial integration and efficient charge separation. By virtue of coupling at the interface, as confirmed by XPS, 57Fe Mössbauer spectroscopy, and DFT calculations, the BMFe catalyst promoted the transfer of electron–hole pairs via Z-scheme and improved the chemical activation of hydrogen peroxide. The subsequent holes, free radicals, and nonradicals can effectively and continuously decompose pollutants, achieving a positive synergistic effect between photocatalysis and Fenton reactions. Simultaneously, the specially designed BiOX(X = Br, Cl)/MIL-53(Fe) and BiOI/Fe-MOFs(MIL-101, MIL-88) heterojunctions also exhibited advanced oxidative capacity for organic pollutants. Given their practical value for industrial applications, BMFe beads (1.0 ± 0.15 mm) synthesized via a blend cross-linking method can significantly advance long-term stability and recyclability. The integration of Fe-based metal–organic frameworks with bismuth oxyhalide semiconductors provides a new perspective on developing heterojunction catalysts for environmental remediation.

BACKGROUND It is of great benefit to recycle excess sludge, which is rich in inorganic and organic nutrients, as the substrate material for yeast growth. This study focused on the disposal of residual liquid of sludge after pretreatment. Candida utilis was firstly chosen to be cultivated in the sludge hydrolyzate for simultaneous efficient nutrients removal and yeast utilization through aerobic process. RESULTS C. utilis cultivated in excess sludge hydrolyzate with 20 g L−1 glucose gained the highest dry weight (6.10 ± 0.15 g L−1) and crude protein yield (1807.68 ± 9.12 mg L−1). Meanwhile, the highest nutrient removal efficiency (TN: 88.5%; TP: 97.1%) was obtained in such conditions. The protein content in the yeast reached 366.7 mg g−1, with all essential amino acids accounting for about 30%, which basically met the nutritional requirements of protein. According to the Excitation‐emission matrix spectra (EEMs) analysis, the yeast can consume most of the organic matter by the end of fermentation. CONCLUSION The alternative approach by applying Candida utilis for converting excess sludge into microbial biomass is very efficient when it comes to nutrients removal in excess sludge and producing proteins with a high content of essential amino acids. This study indicated that C. utilis could be an alternative strain to treat excess sludge hydrolyzate with addition of glucose at appropriate concentration. © 2020 Society of Chemical Industry (SCI)

“…As summarized in Figure 2f and Table S1, the good combination of catalytic activity and reusability indicates that the current 3DP MG/30Cu catalyst is superior to the crystalline or amorphous catalysts reported so far. For example, the catalytic activity of 3DP MG/30Cu is more than 70 times higher than that of the state-of-the-art crystalline catalyst (cobalt phosphide/carbon composite 31 ) and is comparable to those of the best MG catalysts (e.g., Fe 81 Si 2 B 10 P 6 Cu 1 32 and Fe 83 Si 2 B 11 P 3 C 1 20 ). Additionally, the reusability exceeds 100 cycles (actually, this value can be further increased if the experiments were continued) for the 3DP MG/30Cu catalyst, which is remarkable when compared to those of the nanoparticulate catalysts (∼10 cycles), the best MG ribbon catalyst (Cu-based MG, ∼80 times), and the 3D printed Febased MG composite catalyst (∼45 times) reported thus far.…”

Finding highly efficient and reusable catalysts for advanced oxidation processes is a crucial endeavor to resolve the severe water pollution problems. Although numerous nanocatalysts have been developed in the past few decades, their recyclability along with sustainably high catalytic efficiency still remain challenging. Here, we propose a new strategy for designing efficient and reusable catalysts, that is, introducing Cu as a reductant into a metallic glass-based catalyst and constructing three-dimensional hierarchical porous architectures via a laser 3D printing technique. The as-printed 3D porous MG/Cu catalysts exhibit exceptional catalytic efficiency in degrading RhB with a normalized rate constant approximately 620 times higher than commercial nano zero-valent iron, outperforming most reported Fenton-type catalysts so far. Strikingly, the catalysts exhibit an excellent reusability and can be used more than 100 times (the highest record so far) without apparent efficiency decay. It is revealed that Cu-doping could improve the surface reducibility and promote the electronic transfer, rendering the 3D-printed MG/Cu catalysts with a sustainably active Fe(II)-rich surface and, therefore, unprecedented reusability. This work offers a broadly applicable design route for the development of advanced catalysts with an outstanding combination of activity and reusability for wastewater treatments.
