Photocatalytic degradation of ethylene in cold storage using the nanocomposite photocatalyst MIL101(Fe)-TiO2-rGO

MIL-101(Fe)@Nb2C MXene for efficient electrocatalytic ammonia production: an experimental and theoretical study

“…3b), a series of sharp signals correspond to the characteristic peaks of Fe 2p, C 1s, and Nb 3d, respectively, confirming the existence of Fe, C, and Nb elements. MIL-101(Fe)@Nb 2 C exhibited Fe 2p characteristic peaks 54 at E b = 712.13 eV for Fe 3+ 2p3/2, E b = 725.68 eV for Fe 3+ 2p1/2, E b = 710.98 eV for Fe 2+ 2p3/2 and E b = 724.38 eV for Fe 2+ 2p1/2 (Fig. 3c).…”

PI/TiC/TiO2 with Z-scheme heterostructure for the photocatalytic degradation of organic dyes

“…This multi-stage mesoporous network structure might provide a more convenient transmission path for photogenerated carriers. 25 More active sites for dye molecule attachment could be provided by the large specific surface area, while more space for dye molecule transport within the membrane could be provided by the large pore volume. These have all been beneficial to photocatalytic degradation in reported research.…”

“…The valence band (VB) potential of TiO 2 was 3 eV and the highest unoccupied molecular orbital (HOMO) of PI was 1.95 eV, according to eqn (7), E VB/HOMO = E CB/LUMO + E g where E VB is valence band energy, E CB is conduction band energy and E g is band gap energy. 24,25 By comparing the energy band positions of TiO 2 and PI with the standard redox potentials of H 2 O/˙OH (2.2 eV) and OH − /˙OH (1.99 eV), the transfer path of electrons (e − ) in the photocatalyst was deduced, which was of great significance for further understanding the mechanism of interfacial charge separation and transfer.…”

Tumor microenvironment‐activatable oridonin‐loaded iron‐based metal–organic frameworks for targeting cancer therapy

“…34,35 Nano-scaled Fe-MOF not only has large porosity, high surface area, and good biocompatibility but also has high structural stability due to its dense inorganic structural units with strong Fe-O bonding. 36 The stable cage structure of Fe-MOF can collapse in the acidic environment of tumors and release the loaded drug molecules and Fe 3+ ions. 37 In addition, the amino groups on its surface can connect a variety of functional molecules for nanoparticle modification.…”
