Aqueous miscible organic solvent treated NiTi layered double hydroxide De-NOx photocatalysts

Efficient one-pot syntheses of secondary amines from nitro aromatics and benzyl alcohols over Pd/NiTi-LDH under visible light

“…The absorption with the absorption edge extending to 500 nm is due to the ligand-to-metal charge transfer from an octahedral Ti 4+ to O 2− , while the broad band in the 600–800 nm region is attributed to the d–d transition for Ni 2+ . 35 The deposition of metallic Pd nanoparticles on NiTi-LDHs led to only a slightly enhanced light absorption in the 400–800 nm region (Fig. 4).…”

“…NiTi-LDH was previously reported for photocatalytic oxygen evolution 34 and abatement of NO x . 35 Previous studies have revealed that NiTi-LDH exhibits superior photocatalytic activity due to the existence of abundant oxygen defects on the surface, which act as the trapping sites for the charge carriers and lead to improved electron/hole separation. 29,34 The as-obtained Pd/NiTi-LDH nanocomposite was found to exhibit superior performance for the light-initiated one pot synthesis of secondary amines via the N -alkylation of nitro compounds by alcohols.…”

Energy-efficient electrochemical ammonia production from dilute nitrate solution

“…The desorption of water in the interlayer region occurs below 200 °C, and the LDH structure collapses due to dehydration of hydroxyl ions on the cationic layers and the pyrolysis of anions in the interlayers between 200 °C and 400 °C. 30 The X-ray absorption spectroscopy (XAS) were conducted to probe the local electronic structure around Ni and Fe cations in Ni 3 Fe–CO 3 LDH. The valence state of Ni in Ni 3 Fe–CO 3 LDH was revealed by comparing the Ni K-edge X-ray absorption near-edge spectroscopy (XANES) spectra of Ni(OH) 2 and Ni metal (Fig.…”

Boosting NIR Laser Marking Efficiency of a Transparent Epoxy Using a Layered Double Hydroxide

“…In addition, the refractive index of Mg x Al-CO 3 LDH (∼1.5) closely matches many polymeric materials, e.g., epoxy resins (∼1.50–1.59), PP (∼1.50–1.54), PE (∼1.52), allowing for the creation of highly transparent (low scattering) polymer/Mg x Al-CO 3 LDH composites. , Furthermore, the large bandgap for Mg x Al-CO 3 LDH means it has no impact on the optical absorbance of the polymers. Although, Mg x Al-CO 3 based LDHs has been widely used in many applications such as gas barrier, − electrolysis, − CO 2 capture, − catalysis, , and biomedicine . We believe its use as a synergistic laser marking additive has not yet been explored.…”
