As environmental regulations are becoming stricter, new techniques must be developed for the removal of trace concentrations of heavy metals from mineral processing effluents. Foam separation techniques are an interesting alternative to more conventional processes such as ion exchange because of their efficiency to treat dilute aqueous streams. In this paper, the simultaneous removal of Cd2

The as-prepared hierarchical GMM foam yields a monographical graphene foam conformally covered with an intertwined, densely packed CNT/MnO2 nanowire nanocomposite network. Symmetrical electrochemical capacitors (ECs) based on GMM foam electrodes show an extended operational voltage window of 1.6 V in aqueous electrolyte.

Manganese is an element that is often found in the ground. Many manganese ores can be found, mainly oxides (pyrolusite, vernadite, etc.) and occasionally carbonates (rhodochrosite), silicates, sulphides, etc. In natural water, manganese will usually be present in the soluble ionised form, Mn 2+, and sometimes as MnOH + (very basic pH).

Manganese oxide (MnO2) is one of the most promising intercalation cathode materials for zinc ion batteries (ZIBs). Nickel foam (0.5 mm thick, 100 PPI) was purchased from Qijing Trading Co

3D-Printed Ultralight, Superelastic Reduced Graphene Oxide/Manganese Dioxide Foam for High-Performance Compressible Supercapacitors. Wanqiu Cao.

Neuron-like hierarchical core–shell manganese sulfide@Cu2S (MCS) arrays were synthesized on Ni foam by a simple hydrothermal method.

The Manganese dioxide (MnO 2) nanoparticles uniformly grown on graphene/Ni foam have been fabricated by a simple and effective electrodeposition method as electrode (MnO 2 /G/Ni foam) materials for electrochemical capacitors. The morphological and structural of the nanocomposites were studied by SEM, XRD and XPS. Electrochemical properties were tested by cyclic voltammetry (CV

capacitor with high energy and power densities based on a composite of graphene foam (GF) with ∼80 wt% of manganese oxide (MnO2) deposited by hydrothe.
