Abstract Layered double hydroxides as typical supercapacitor electrode materials can exhibit superior energy storage performance if their structures are well regulated. In this work, a simple one-step hydrothermal method is used to prepare diverse nickel–cobalt layered (NiCo-LDHs), in which the different contents of urea regulate nanostructures NiCo-LDHs. The results show that decrease content ...

Transition metal layered double hydroxides (LDHs) are one of the great potential electrode materials for pseudocapacitors. However, the aggregation and low conductivity of these metal compounds will constrain electrolyte ion and electron transfer and further affect their electrochemical performances. The nano-structured carbon coupled with the LDH matrix can act as an active component or conduc...

In the present work, the interaction ofFe3O4@CaAl LDH@ Lamivudine with human serum albumin (HSA) was investigated by applying UV–vis and fluorescence spectra. The nanocomposite was quenching the natural fluorescence of HSA, which was indicated the static quenching mechanism. The consequences demonstrated that this nanocomposite can strongly bind to HSA molecules. According to fluorescence quenc...

Efficient and stable bifunctional electrocatalysts for water splitting is essential producing hydrogen alleviating huge energy consumption. Meanwhile, charge transfer engineering an efficient approach to modulate the localized electronic properties of catalysts tune electrocatalytic performance. Herein, we tactfully fabricate PtFeNi alloys/NiFe layered double hydroxides (LDHs) heterostructure b...

Guest molecules in layered double hydroxides (LDHs) may be located both on the surface and interlayer gallery. In this work, a comparative study of various IR spectroscopic methods coupled with X-ray diffraction (XRD) is presented, which makes it possible to distinguish between two possibilities. During experimental first, CaAl-LDHs intercalated nitrate/carbonate ions were transformed d-glucona...

This study focuses on the application of nanostructured Mg-Al layered double hydroxide as a promising adsorbent in desulfurization of dibenzothiophene, an aromatic sulfur bearing compound from gasoil model. The Mg-Al LDH was synthesized by a co-precipitation method and characterized by FT-IR, XRD, EDX and SEM. The XRD and FT-IR approved the layered structure and crystalline form of the adsorben...

The transition metal-based layered double hydroxides (LDHs) for high-performance supercapacitor applications were synthesized by the hydrolysis dropping method. We found that sequence of cation and anion solutions has a strong influence on microstructural electrochemical properties LDHs. NiAl LDHs obtained Ni 2+ solution into AlO 2- have obvious structures with particle size order micrometers. ...
