A new electrochemical synthesis route was developed for the fabrication of Fe-containing layered double hydroxide (MFe-LDHs, M 1⁄4 Ni, Co and Li) hierarchical nanoarrays, which exhibit highly-efficient electrocatalytic performances for the oxidation reactions of several small molecules (water, hydrazine, methanol and ethanol). Ultrathin MFe-LDH nanoplatelets (200–300 nm in lateral length; 8–12 ...
In this work, ZnLaAl layered double hydroxides (LDHs) were prepared by the co-precipitation method, and ZnLaAl-LDHs nanosheets embedded in sol-gel coating for corrosion protection of 6061 aluminum alloys. The structure, morphology, long-term anti-corrosion performance modified with investigated. structure morphology analysis showed that are finer than those ZnAl-LDHs, results suggesting La can ...
Highly ordered transparent composite films of CdS and layered double hydroxides (LDHs) have been fabricated using a template synthesis method; the size of the CdS particles in the LDH host can be controlled by adjusting the length of time of the reaction with H(2)S.
A facile method for the synthesis of Zn2Al-borate and Mg3Al-borate layered double hydroxides (LDHs) with extremely high specific surface areas of 458.6 and 263 m(2) g(-1) and containing delaminated nanosheets is reported. To the best of our knowledge, this is the first report of LDH powders that still remain exfoliated on drying.
Ethanol has been used as a renewable hydrogen-donor in the conversion of lignin model molecule subcritical conditions. Noble metal-free porous mixed oxides, obtained by activation Cu−Ni−Al and Cu−Ni−Fe layered double hydroxide (LDH) precursors, have heterogeneous catalysts for Meerwein-Ponndorf-Verley (MPV) hydrogen transfer further hydrogenation ethanol dehydrogenation products. Both Cu/(Cu+Ni...
Salen–metal complexes (SalenM) were successfully intercalated into ZnCr layered double hydroxides (LDHs) through coprecipitation method, then a series of novel organic–inorganic hybrid materials were obtained. The structure and properties of the materials were thoroughly characterized by inductively-coupled plasma atomic emission spectrometry (ICP-AES), powder X-ray diffraction (XRD), Fourier t...
Calcined and organo-modified Zn-Al layered double hydroxides (LDHs) were studied as adsorbents and photocatalysts for removal of cationic dye, as namely methylene blue (MB). Zn-Al LDHs with a cationic ratio of 2:4 were obtained by the coprecipitation method. As-synthesized samples were calcined at different temperatures and the phase transformations were investigated by XRD, TG/DTG, and UV-vis-...
A series of metal cation modified layered-double hydroxides (LDHs) and mixed oxides were prepared and used to be the selective oxidation of toluene with O2. The results revealed that the modified LDHs exhibited much higher catalytic performance than their parent LDH and the modified mixed oxides. Moreover, the metal cations were also found to play important roles in the catalytic performance an...
Meropenem (MER) antibiotic is removed from an aqueous solution using Mg-Al-layered double hydroxide (Mg/Al-LDHs) which serves to functionalize the principal object of enquiry in this paper–sunflower husks (SFH). The former sample demonstrated a 51% removal MER while latter 67% MER. One areas explored was impact rise calcination temperatures resulted concurrent increase surface area and porosity...
