Multiple catalytic sites of Fe-N and Fe-N-C single atoms embedded N-doped carbon heterostructures for high-efficiency removal of malachite green

Efficient degradation of organic contaminants via a novel iron-based poly(ionic liquid)/polydopamine composite as the heterogeneous Fenton catalyst

“…As calculated, R = 0.79 g g −1 min −1 is achieved by PDVIm-Fe/PDA, which is among the best seven (from 0.78 to 0.87 g g −1 min −1 ) in all the 19 systems using various heterogeneous catalysts and even close to the best homogeneous catalyst with R = 1.1 g g −1 min −1 (Table S3†). Both k and R from PDVIm-Fe/PDA are much larger than those from most of the reported heterogeneous catalysts including iron-based catalysts such as Fe–N–C/CN x , 50 core–shell Fe 3 O 4 @SiO 2 , 51 and Fe–TiO 2 /AC, 52 suggesting the structural superiority of the designed PDVIm-Fe/PDA in this work.…”

Fe–Decorated Nitrogen–Doped Carbon Nanospheres as an Electrochemical Sensing Platform for the Detection of Acetaminophen

“…Fe–NC–800 has the following atomic percentages: C (88.61%), O (5.33%), N (4.02%), and Fe (2.04%). The C–C (284.8 eV), C–N (286.28 eV), C–O/C=O (288.99 eV), and π–π* transition (292.42 eV) transitions can be distinguished in the C1s spectra of NC–800 and Fe–NC–800, respectively ( Figure 3 B,E) [ 24 ]. Because C–N was next to Fe–Nx and the C–N bond preferentially fractured, the quantity of C–N species in Fe–NC–800 reduced when compared to NC–800, which improved the catalytic performance [ 25 ].…”

Carbon nitride based materials: more than just a support for single-atom catalysis

“…The procedure has been replicated many times with variations in the order of the additions and extended to different metals, including Fe, Cu, Mn, Cr, Co and Ba. 310,319,322,[436][437][438][439][440][441][442][443] DMSO or ethylene glycol is also used as an organic solvent to dissolve melamine and cyanuric more efficiently. Nevertheless, all these procedures rely on the formation of a melamine-cyanuric acid supramolecular assembly held together by hydrogen bonding.…”
