“…All the N 2 isotherms are similar and reveal the type I isotherms that are related to the microporous material. 55 There is a hysteresis loop of type H3 58 in all isotherms due to the presence of defects in MOF-801, which confirms the presence of mesopores. 59 The pore size distribution is estimated using the Barrett–Joyner–Halenda (BJH) method from the adsorption and desorption branches of the N 2 isotherms.…”

“…Meanwhile, both CeO 2 and BM-CeO 2 showed type IV isotherms with H3 hysteresis loops (Figure S4a in Supporting Information), indicating the presence of mesopores. 40 The pore size distribution of CeO 2 and BM-CeO 2 also affirmed their mesoporous feature (Figure S4b in Supporting Information). Moreover, the BM-CeO 2 sample even exhibited slight aggregation compared with CeO 2 , which led to a decrease in the specific surface area from 111.0 m 2 g −1 for CeO 2 to 43.6 m 2 g −1 for BM-CeO 2 .…”

Organophosphorus esters (OPEs) are important chemicals functioning as extractants, plasticizers, flame retardants, solvents, additives, etc., and are also recognized as hazardous organic liquids generated from industrial processes. Herein, we developed a CeO2-catalyzed degradation with simultaneous phosphorus immobilization technology to treat typical OPE solvents. Under the investigated reaction conditions of a temperature of 180 °C, a reaction time of 3 h, and a dosage of ball-milled CeO2 of 19.8 g mL–1 of the OPE, the model pollutant of tributyl phosphate (TBP) was efficiently degraded with phosphorus immobilization efficiency near 100%. Meanwhile, the mineralization efficiency of TBP was also as high as 98%, which was reflected by the chemical oxygen demand change of liquid products. Gaseous products generated from CeO2-catalyzed TBP degradation could also fulfill the requirements of an environmental standard. Further mechanism studies indicated that the surface oxygen vacancy in CeO2 induced the in situ formation of superoxide radicals, which dominated TBP degradation. During catalytic degradation, the P-containing species were mainly immobilized as cerium phosphate, while the hydrocarbon chains of TBP were degraded into small molecules and finally mineralized into inorganic species. The developed CeO2-catalyzed OPE degradation approach was also applicable to aromatic and halogenated OPEs, i.e., tricresyl phosphate and tris(2-chloroethyl) phosphate. This study provided a possible alternative for waste treatment of the waste of OPEs with low environmental risks.

Fe(III) is introduced into ball clay by the peeling‐intercalation technique, and mixed with oyster shell (B‐FB‐OS), pelletized, and calcined to form granular materials (FB‐OS) demonstrated that the presence of SiO2 and Fe(III) is favorable for CaCO3 pyrolysis, and the pyrolysis temperature of CaCO3 in B‐FB‐OS is 46 °C lower than that of oyster shell. A large amount of flocculent products are generated on the surface of FB‐OS after phosphorus removal, but pore channels are still observed. EDS analysis and theoretical analysis have shown that the flocculent products contained Ca3(PO4)2, suggesting the occurrence of chemisorption. Fe3+/Ca2+ has synergism, the maximum adsorption capacity of FB‐OS is 244.65 mg g−1, and the phosphorus concentration after treatment is lower than 1 mg L−1. The kinetic adsorption behavior of FB‐OS is applicable to Pseudo‐second‐order rate equation. The results of the Weber–Morris model demonstrated that the adsorption process is controlled by outer film diffusion and intraparticle diffusion together. The thermodynamic behavior of FB‐OS is consistent with the Freundlich isotherm model (R2 = 0.945). The comprehensive analysis indicated that FB‐OS is multilayer adsorption and nonuniform surface adsorption, and has a strong phosphorus removal ability.
