“…The presence of Cd +2 peak in Figure S1b confirmed the adsorption of Cd +2 onto the MoO 3 /Ppy surface. Elemental mapping of MoO 3 /Ppy (Figure S1c) and MoO 3 /Ppy‐Cd (Figure S1d) confirmed the presence of Mo, O, N, C, and Cd . TEM micrograph of MoO 3 /Ppy nanocomposite (Figure a) suggested that MoO 3 nanoparticles were randomly distributed into irregular chainlike structure of Ppy matrix .…”

Molybdenum trioxide/polypyrrole (MoO3/Ppy) nanocomposite was prepared via oxidative polymerization of pyrrole monomer with MoO3 nanoparticles. The adsorption of Cd+2 and nile blue (NB) onto the nanocomposite was investigated in terms of various process parameters. The characterization of MoO3/Ppy nanocomposite was carried out by Fourier transform‐infrared spectroscopy, X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, and energy dispersive X‐ray spectroscopy. Higher R2 (0.992–0.997 for Cd+2 and 0.997–0.998 for NB) and lower standard error of estimation values (1.04–1.82 for Cd+2 and 0.87–1.07 for NB) for Freundlich isotherm highlighted the multilayer adsorption onto heterogeneous nanocomposite surface. The higher Qm values at 323 K for Cd+2 (181 mg/g) and NB (189 mg/g) compared to many reported adsorbents proved the adsorptive superiority of MoO3/Ppy. The energy of adsorption (E) values from Dubinin–Radushkevich model was 1.26–1.38 and 1.36–1.44 kJ/mol for Cd+2 and NB, respectively, suggesting physical adsorption. Pseudo‐second order kinetic model governed the adsorption of Cd+2 and NB with intraparticle and liquid film diffusion controlling the mechanism. The negative ΔG values (8.4–9.4 kJ/mol) and positive ΔH values (2.5–6.1 kJ/mol) implied spontaneous and endothermic adsorption process. The positive ΔS values (0.036–0.048 kJ/mol/K) indicated increased randomness at MoO3/Ppy‐Cd+2 or NB interface. The MoO3/Ppy nanocomposite proved to be suitable and efficient adsorbent for sequestering of Cd+2 and NB from aqueous solution.

“…It was inferred from Figure S12 that intraparticle diffusion mechanism was not solely controlling adsorption kinetics as the plot did not pass through the origin. The higher values of C i for Cd +2 (24)(25)(26)(27)(28) and NB (81-87) suggested greater effect of external surface on adsorption mechanism. 65…”

As one of the most promising alternatives to next‐generation energy storage systems, aluminum batteries (ABs) have been attracting rapidly increasing attention over the past few years. In this review, we summarize the recent advancements of ABs based on both aqueous and non‐aqueous electrolytes, with a particular focus on rechargeable non‐aqueous ionic liquid‐based aluminum‐ion batteries (AIBs). Progress of the current intensive investigation on the development of cathode materials and electrolytes in non‐aqueous AIBs are discussed. Then research efforts towards aqueous ABs are described to give readers a broader view of the aluminum battery family. Finally, the review summaries the key challenges underpinning ABs and provides future research perspectives on this growing field.

Supercapacitors are introduced and reviewed as devices with very high electric power capability suggested to support and supplement other devices for electrochemical energy storage and conversion with higher energy content but lower power. They are currently of significant importance on the device and local (end-user) level already providing resources to meet power surge demands. In larger mobile systems (vehicles) they help meeting this demand and also offer high power storage capabilities when braking. On an even higher level, they can provide support for maintaining power quality and help in peak shaving. A brief historic background and general information is followed by an overview of materials and their combination into already marketed devices and in possible systems under development.
