“…1 Among noble-metal free OER catalysts, transition metal based layered double hydroxides (TM LDHs), [2][3][4] especially nickel-based LDHs such as NiFe LDH, [5][6][7] NiV LDH, 8,9 NiCr LDH, 10 NiCoFe LDH, 11,12 etc., exhibit the most efficient performance toward water oxidation. 3,13,14 However, little research has been done on NiCu LDH for the OER, due to the low catalytic activity of Cu ions and the weak synergistic effects between Ni and Cu.…”

“…Instead of simple anions, LDH hybrid materials can be synthesized by the intercalation of polyoxometalates [5], anionic metal complexes [6] and organic species like drugs, dyes, amino acids, synthetic polymers and biopolymers [4,7,8]. Owing to their compositional versatility, a variety of LDH with different physical-chemical properties can be obtained for diverse applications, ranging from heterogeneous catalysis [9], environmental remediation [10], energy production [11], drug carrier and diagnosis in medicine [12] up to nanoreactors for prebiotic life [13].…”

Carboxymethylcellulose (CMC), a polymer derived from biomass, was intercalated into layered double hydroxides (LDH) composed by M2+/Al3+ (M2Al-CMC, M = Mg or Zn) and evaluated as precursors for the preparation of biocarbon-based nanocomposites by pyrolysis. M2Al-CMC hybrids were obtained by coprecipitation and characterized by X ray diffraction (XRD), vibrational spectroscopies, chemical analysis, and thermal analysis coupled to mass spectrometry. Following, pyrolyzed materials obtained between 500–1000 °C were characterized by XRD, Raman spectroscopy, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Above 600 °C, Raman spectra of all samples showed the presence of graphitic carbon, which plays a role in the degree of crystallinity of produced inorganic phases (for comparison purposes, M2Al-CO3 materials were investigated after calcination in the same experimental conditions). XRD patterns of Mg2Al-CMC pyrolyzed between 600–1000 °C showed poorly crystallized MgO and absence of spinel reflections, whereas for Zn2Al-CMC, it was observed well crystallized nanometric ZnO at 800 °C, and ZnAl2O4 and γ-Al2O3 phases at 1000 °C. Above 800 °C, the carbothermic reaction was noticed, transforming ZnO to zinc vapour. This study opens perspectives for nanocomposites preparation based on carbon and inorganic (mixed) oxides through precursors having organic-inorganic interactions at the nanoscale domain.

View full text Add to dashboard Cite

Two‐dimensional (2D) nanomaterials have drawn a wide range of research interests because of their unique ultrathin layered structures and attractive properties. In particular, the electrochemical properties and great variety of 2D nanomaterials make them highly attractive candidates for electrochemical capacitors, such as supercapacitors, lithium‐ion capacitors, and sodium‐ion capacitors. Herein, a comprehensive review of recent progress towards the application of 2D nanomaterials for electrochemical capacitors is provided. Several typical types of 2D nanomaterials are first briefly introduced, followed by detailed descriptions of their electrochemical capacitor applications. Finally, research perspectives and future research directions of these interesting areas are also provided.
