AB  - Reuse and/or recycling of spent adsorbents is taking a central role in modern thinking and catalyzed carbonization is the way forward. Herein we explore the carbonization of adsorbed acetamiprid, in an inert atmosphere, as a way of recycling and producing nitrogen-rich carbon material for potential use in supercapacitors. Added value material and the reuse of the adsorbent were achieved by carbonization at 700 °C under argon. The formation of a nitrogen-doped carbon layer as an active material on the adsorbent, bonded through a C-Si linkage, has been conclusively verified through elemental composition quantification using XPS and EDX measurements. Two-stage catalytic decomposition and condensation of the adsorbed pesticide is followed by TGA and TPD-MS. Attained carbon-based materials give stable Faradaic capacitance with a slight dependency on the number of adsorbing cycles. Capacitance calculated with respect to the adlayer carbon material reaches values as high as 610 F g−1. Galvanostatic Charge/Discharge measurement confirmed the stability of explored materials with a slight increase in capacitance over 1000 cycles. The presented results envisage electroactive materials preparation from environmental pollutants, adding value to spent adsorbents.

AB  - A set of samples of SrGd2O4 doped with Sm3+ and Dy3+with different concentrations was prepared via glycine-assisted combustion synthesis. All of the diffraction peaks are related to the pure orthorhombic lattice SrGd2O4, according to X-ray Powder Diffraction investigation. The Energy Dispersive X-ray Spectroscopy chemical characterization revealed that the structure included all desired elements. Field Emission Scanning Electron Microscopy was used to capture the morphology, which showed porous aggregated particles consisting of roughly 50 nm-sized spherical particles. The Mercury Intrusion Porosimetry was used to establish where voids originated, and the results showed that samples have a real permanent 3D pore structure. X-ray Photoelectron Spectroscopy verified the successful incorporation of Dy3+ and Sm3+ ions in the matrix. Down-conversion luminescence spectra were recorded and typical emission transitions were found for either Sm3+ (4G5/2→6H5/2, 4G5/2→6H7/2, 4G5/2→6H9/2) or Dy3+ (4F9/2→6H15/2 and 4F9/2→6H13/2) ions. Calculation of the energy band gap using UV-VIS Diffuse Reflectance Spectroscopy yielded values of 4.3 eV for both doped samples. Using UV-VIS Absorption Spectroscopy, the photocatalytic degradation process was observed. After 4 h of simulating Sun exposure, an analysis of the photocatalytic properties revealed that approximately 50% of the Rhodamine B had been mineralized.

AB  - Cathodic material for sodium-ion rechargeable batteries based on NaxMnO2 were synthesized by glycine nitrate method and subsequent annealing at high temperatures. Different crystal structures with different morphologies were obtained depending on the annealing temperature: hexagonal layeredα-Na0.7MnO2.05 nanoplates were obtained at 850 ◦C, while 3-D tunnel structured Na0⋅4MnO2 and Na0⋅44MnO2, both with rod-like morphology, were obtained at 800 ◦C and 900 ◦C, respectively. The investigations of the electrochemical behavior of obtained cathodic materials in aqueous NaNO3 solution have shown that Na0⋅44MnO2 obtained at 900 ◦C has shown the best battery performance. Its initial discharge capacities are 123.5 mA h/g, 113.2 mA h/g, and 102.0 mA h/g at the high current densities of 1000, 2000 and 5000 mA/g, respectively.

AB  - Nanostructured nickel thin films were deposited on glass using glancing angle deposition (GLAD) technique. Cross-sectional field emission scanning electron microscopy images have shown that obtained Ni thin films consist of vertical, tilted or zigzag nano-scaled columns, while X-ray diffraction have shown that (111) orientation prevailed. X-ray photoelectron spectroscopy revealed that apart from metallic nickel, NiO and Ni(OH)(2) were also present in lower amount. Cyclic voltammetry in alkaline solution has shown that hydrogen evolution reaction (HER) was significantly catalyzed on all columnar nanostructures compared to Ni(poly). This was ascribed to the high electroactive surface area (EASA) of porous nickel columns. EASAs for vertical, tilted and zigzag Ni thin layers were higher 32, 25.3, and 24.9 times, respectively, than their geommetric areas. Accordingly, Ni thin films with vertical columns have shown the highest activity for HER.
