“…FeOOH nano-rods grown on a carbon substrate have been demonstrated to operate as capacitors over 5000 charge:discharge cycles without a decrease in capacitance [129]. The specific capacitance of the FeOOH decreases as the structure becomes laminated [129], e.g., through the accretion of green rust layers ( Figure F1), or accretion and coalescence of FeOOH colloids ( Figure F1).…”

Batch treatment of water (0.2 to 240 L) using Fe 0 (44,000-77,000 nm) in a diffusion environment operated (at −8 to 25 °C) using: (a) no external energy; (b) pressurized (<0.1 MPa) air; (c) pressurized (<0.1 MPa) acidic gas (CO2); (d) pressurized (<0.1 MPa) anoxic gas (N2); (e) pressurized (<0.1 MPa) anoxic, acidic, reducing gas (H2 + CO + CO2 + CH4 + N2), reduces the salinity of water. Desalination costs increase with increasing NaCl removal. The cost of reducing water salinity from: (i) 2.65 to 1.55 g·L . Desalination is accompanied by the removal, from the water, of one or more of: nitrate, chloride, fluoride, sulphate, phosphate, As, B, Ba, Ca, Cd, Co, Cu, Fe, Mg, Mn, Na, Ni, P, S, Si, Sr, Zn. The rate of desalination is enhanced by increasing temperatures and increasing HCO3 − /CO3 2− concentrations. The rate of desalination decreases with increasing SO4 2− removal under acidic, or pH neutral, operating conditions.

“…Hence, fabricating a supercapacitor that can store as much energy as the lithium-ion batteries will be considered as a breakthrough in the field of electrical energy storage. [12][13][14] These synthesis methods include hydrothermal, electrodeposition, spray deposition technique, and microwave method. 7, 8 Iron oxides and hydroxides are a class of promising materials for pseudocapacitors owing to their high theoretical specific capacitance, naturally abundant and being low cost and environmental benign.…”

In this work, we study the crystallization of FeOOH nanorods via hydrolysis of FeCl 3 ⋅6H 2 O solution with low-temperature hydrothermal route (100°C). The effect of Fe 3+ concentration and the solution pH value on the crystallized morphology and size of FeOOH nanorods were systematically studied based on chemical reaction and crystallization process. The electrochemical performance of the as-obtained FeOOH materials is evaluated as supercapacitor and the effect of Fe 3+ concentration on the pseudocapacitance of iron-based materials are also discussed. FeOOH electrode materials obtained in 0.2M FeCl 3 ⋅6H 2 O solution display the highest specific capacitance of 714.8 F/g, which is higher than reported values of FeOOH electrode materials. The present work demonstrates a simple hydrolysis route to synthesize high capacitance electrode materials.

Supercapacitors (SCs) have great promise as the state‐of‐the‐art power source in portable electronics and hybrid vehicles. The performance of SCs is largely determined by the properties of the electrode material, and numerous efforts have been devoted to the explorations of novel electrode materials. Recently, iron‐based materials, including Fe2O3, Fe3O4, FeOOH, FeOx, CoFe2O4, and MnFe2O4, have received considerable attention as very promising electrode materials for SCs due to their high theoretical specific capacitances, natural abundance, low cost, and non‐toxicity. However, most of these Fe‐based SC electrodes suffer from poor conductivity and/or electrochemical instability, which seriously impede their implementation as high‐performance electrodes for SCs. To settle these issues, substantial efforts have been made in improving their conductivity and cycling stability, and great processes have been achieved. Here, recent research advances in the rational design and synthesis of diverse Fe‐based nanostructured electrodes and their capacitive performance for SCs are presented. Besides, challenges and prospects of Fe‐based materials as advanced negative electrodes for SCs are also discussed.
