Acceleration of Fe3+/Fe2+ cycle in garland-like MIL-101(Fe)/MoS2 nanosheets to promote peroxymonosulfate activation for sulfamethoxazole degradation

A photothermal and conductive composite hydrogel membrane for solar-driven synchronous desalination and salinity power generation

“…The main reason was that the photothermal layer reduces the evaporation heat of water, and the polyethylene foam at the lower layer prevents the downward transfer of heat. 25–28 The CHN-CB membranes replaced the ion exchange membranes used in traditional salinity difference power generation, greatly reducing the cost of the evaporator (Table S1†). We utilized CHN-CB membranes to conduct evaporation stability tests for 15 days.…”

Degradation of Orange G Using PMS Triggered by NH2-MIL-101(Fe): An Amino-Functionalized Metal–Organic Framework

“…In Figure 4e, the N1s spectrum showed two binding energy peaks at 400.10 eV, 399.10 eV, corresponding to N-C and -NH2, respectively [39]. The Fe 2p spectrogram showed two fitted peaks in Figure 4c; the corresponding peaks of Fe 3+ were at 2p 1/2 and 2p 3/2 with binding energies of 727.44, 713.03 eV [35]; and the corresponding peaks of Fe 2+ were at 2p 1/2 and 2p 3/2 with binding energies of 725.06, 711.31 eV [36,37], respectively. For the XPS spectrum of O 1s in Figure 4d, three peaks appearing at 530.50 eV, 531.89 eV, 532.79 eV corresponded to Fe-O, C=O, and O-H, respectively [38].…”

“…The absorption peaks located at 1251 cm −1 and 1628 cm −1 corresponded to ν(C-N) and δ(N-H) [32], respectively, and the peaks at 3357 cm −1 and 3442 cm −1 were due to the stretching vibration of -NH2 [33], which confirmed the presence of amino functional groups. The Fe 2p spectrogram showed two fitted peaks in Figure 4c; the corresponding peaks of Fe 3+ were at 2p1/2 and 2p3/2 with binding energies of 727.44, 713.03 eV [35]; and the corresponding peaks of Fe 2+ were at 2p1/2 and 2p3/2 with binding energies of 725.06, 711.31 eV [36,37], respectively. For the XPS spectrum of O 1s in Figure 4d, three peaks appearing at 530.50 eV, 531.89 eV, 532.79 eV corresponded to Fe-O, C=O, and O-H, respectively [38].…”

Confinement of MOF etching-induced hollow heterostructured cages in the carbon framework for efficient peroxymonosulfate activation

“…As a strong solid oxidant, it is safer and easier to store than H 2 O 2 . 3,4 In this process, SO 4 À can be obtained via the activation of peroxodisulfate (PDS) and peroxymonosulfate (PMS) upon appropriate heating and in the presence of a catalyst, transition metals, ultraviolet, or a combination of these. [5][6][7] It was reported that the cobalt-based catalyst is demonstrated to be the best activator for PDS or PMS for effective pollutant degradation.…”
