A new carboxyl-copper-organic framework and its excellent selective absorbability for proteins

Iron impregnated carbon materials with improved physicochemical characteristics

“…It is pertinent to mention here, that along with the loss of water molecules from M2, the probable transformation of Fe(OH) 3 into ␣-Fe 2 O 3 and phase transformation of ␥-Fe 2 O 3 to ␣-Fe 2 O 3 also occurs below 400 • C, resulting in the disappearance of micro-pores as described in Section 3.1. Yang et al [64], have reported a similar decomposition of organic (<400 • C) and inorganic ligands (>400 • C) while working on the carboxyl-copper-organic framework.…”

“…The small weight losses in iron-carbon hybrids are probably due to the increased oxygen functionalities. Overall, the weight loss below 400 • C is considered to be due to the discharge of physically and structurally bound water molecules along with the decomposition of organic matter and phase transformations, while the weight loss in the range of 400-800 • C is ascribed to the decomposition of inorganic matter in all the samples studied [64,65]. Above 600 • C, only the inorganic carbon residue is remained.…”

“…6, that the raw AC has shown considerably higher thermal stability as compared to all other ironimpregnated carbon materials. The raw AC has shown a single weight loss of 18.87% below 100 • C, which can be assigned to the loss of physisorbed water or moisture contents from the surface of raw AC [64]. Afterwards, the raw AC did not show any significant weight loss, up to 900 • C. This result was supported by the differential thermal analysis (DTA) showing only single peak corresponding to the only weight loss (18.87%) in the studied range of temperature.…”

Statistical modeling and optimization of heterogeneous Fenton-like removal of organic pollutant using fibrous catalysts: a full factorial design

“…Step size of 0.4 eV/step), and the narrow scan for the chemical state analysis with selected range for individual elements and step size of 0.1 eV/step was performed [41][42][43][44] . Morphological and structural analysis of such fibrous catalysts were extensively studied in our previous reports 20,33 .…”

Facile Synthesis of a Polycatenane Compound Based on Ag-triazole Complexes and Phosphomolybdic Acid for the Catalytic Epoxidation of Olefins with Molecular Oxygen

“…The XPS spectra of N 1s is shown in Figure 10. For trz and Ag-trz 3 , the appearance of binding energies at 399.7 eV is attributed to the N 1s of =Nor -NH-on triazole ring [39][40][41]. Compared with triazole, the binding energies of N 1s in the catalyst 1 shift positively (from 399.7 eV to 399.85 eV), suggesting that relatively strong coordinative interaction is present between Ag + and triazole ligands in this catalyst.…”
