Potassium chloride (KCl), a sodium substitute, faces challenges due to its metallic bitterness. This study investigated the bitterness-masking effect of fucoidan (Fuc), a sulfated polysaccharide, on KCl and its impact on chicken mince quality. Sensory evaluation, rheological analysis, and simulated K + release tests revealed that 1.5 % Fuc reduced KCl bitterness by 73 % while enhancing perceived saltiness by 19 %. Fuc binds to K + via sulfate groups, increasing solution viscosity and slowing oral K + release. Applied to chicken mince, Fuc-KCl solutions improved gel water-holding capacity (WHC) by forming a dense protein-polysaccharide network, reducing cooking loss, and enhancing textural properties (e.g., chewiness and elasticity). LF-NMR and SEM confirmed that Fuc restructured water distribution and refined gel porosity. Molecular docking identified key interactions between Fuc and myosin residues (Thr277, Lys432), stabilizing the gel matrix. This polysaccharide-based strategy effectively masks KCl bitterness, reduces sodium content, and enhances meat quality, offering a novel approach for low-sodium food innovation.

Ti is produced by the Kroll method, mainly by carbothermic chlorination, magnesiothermic reduction, and vacuum distillation, which result in complex processes, low efficiency, and high cost. Although Ti has many excellent properties, its high production costs limit its widespread applications. There is an urgent need to develop new Ti extraction processes to reduce the cost of Ti production. In this study, we propose a new method for the direct preparation of low-oxygen Ti powder from TiO 2 using Mg as a reducing agent and the formation of CeOCl (2Mg ( l ) + TiO 2 ( s ) + 2CeCl 3 ( l ) = Ti ( s ) + 2CeOCl ( s ) + 2MgCl 2 ( l )). First, a deoxidization experiment of Ti with Mg as a deoxidizer was conducted, and the ability of Mg to deoxidize Ti was demonstrated. At 1273 K, when the activity of CeCl 3 was 1, the oxygen concentrations of Ti-A and Ti-B were 380 and 270 ppm, respectively. Subsequently, the TiO 2 reduction experiment was conducted using Mg as the reducing agent. The results showed that MgO activity was effectively reduced by the formation of CeOCl (MgO( s ) + CeCl 3 ( l ) = MgCl 2 ( l ) + CeOCl( s )). When the system reached the Mg/MgCl 2 /CeOCl/CeCl 3 equilibrium, low-oxygen Ti powder below 1000 ppm was directly produced from TiO 2 .

MoB2 is synthesized by the electrochemical reduction of solid MoS2/B mixture in molten NaCl-KCl at 700 °C. Unlike the traditional methods, the electrolysis method employs the low-cost MoS2 feedstock and the boronization reaction happens at a low temperature of 700 °C. The electrochemically induced boronization involves two steps: the electrochemical desulfurization to generate Mo and the reaction of Mo with B to form MoB2. The S2− released from the reduction of MoS2 transfers to the carbon anode and is oxidized to sulfur gas, realizing a green synthetic process. In addition, the influences of molar ratio of MoS2 and amorphous boron and electrolysis cell voltage on the phase composition and morphology of electrolytic products were studied. The obtained MoB2 particles possess a uniform nodular morphology. Overall, this paper provides a straightforward and green process to prepare MoB2 nanoparticles using economically affordable raw materials at low temperature, and this method can be extended to prepare other borides.

Studying the electrodeposition mechanism of La3+ in LiCl-KCl salt is extremely important for understanding the main characteristics of the deposition of An/Ln in the pyrochemical reprocessing of spent nuclear fuels. In this work, cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and Tafel methods were employed to investigate the electrodeposition mechanism and kinetic processes of La3+ on Al, Ga and Al-Ga alloy cathodes in LiCl-KCl eutectic salt at the temperature range of 723−873 K. The EIS spectra were measured by applying a minimum overpotential near the equilibrium potential, and the suitable equivalent circuits were fitted. The values of exchange current density (i0) calculated by EIS ranged from 0.078 to 0.42 A cm−2. Finally, Al2Ga2La ternary and Al3La, Ga6La binary alloys were obtained by the potentiostatic electrolysis, which were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) equipped with energy dispersive spectroscopy (EDS).

The highly effective separation of two adjacent rare earth is significant to the rare earth and nuclear industries. This paper investigates the highly effective separation of Gd over Eu using liquid lead–bismuth eutectic (LBE) alloy cathode in molten LiCl-KCl-EuCl 3 -GdCl 3 by pulse potential electrolysis (PPE). Underpotential deposition of Eu and Gd is observed on the LBE alloy, with a depolarization value far greater than that of the liquid Pb electrode. Furthermore, the higher exchange current density and the lower activation energy of the electrode reaction indicate that the LBE alloy cathode has higher kinetic performance than the liquid Pb. Then, the practical electro-separation in LiCl-KCl-EuCl 3 -GdCl 3 systems is carried out by applying different electrolysis technology. The effects of varying electrolysis methods and parameters on separation factor ( SF ), extraction efficiency, cathode product morphology, and crystal size are studied and compared. The results show that both the extraction efficiency and the separation factor obtained by the PPE are the largest. The calculated extraction efficiency of Gd and the actual separation factor SF Gd/Eu of Gd/Eu could be up to 99.1 % and 759, respectively.

Bismuth (Bi) is a potential cathode material to drive the development of Gd extraction by molten salt electrolysis. However, study on the electrolytic reduction of Gd by Bi electrode in melts has not receive sufficient attention and understanding. Therefore, in this work, the electrochemical reactions, kinetic processes and thermodynamic properties in the electrolytic extraction of Gd were investigated by various electrochemical methods. The electrochemical results showed that only two Gd–Bi alloys were formed in the electrode reaction. Moreover, the exchange current density and activity coefficient during electrolysis were determined by galvanostatic pulse (GP) and Coulomb titration, respectively. The temperature dependence of both exchange current density and activity coefficient was further revealed. Finally, Gd was successfully extracted in the form of alloys through potentiostatic electrolysis.

In this research, the reduction mechanism of Nb(V) under various [F − ]/[Nb n+ ] ratios ( α ) was investigated by a series of electrochemical techniques, such as square wave voltammetry (SWV) and chronopotentiometry (CP). We previously studied the electrode reduction process of Nb(V) and revealed that was Nb(V) → Nb(III) → Nb(I) → Nb in NaCl-KCl molten salt. It was found in this research that the electrode reduction process of Nb(V) ion was shortened to Nb(V) → Nb(III) → Nb when α was equal to 1.0; furthermore, the electrode reduction process of Nb(V) ion transforms to Nb(V) → Nb(IV) → Nb when α was greater than or equal to 5.0. Moreover, the reaction mechanism was also discussed in this work. Metallic niobium was collected on a molybdenum electrode under the condition of higher fluoride content after electrolysis in the melt.

Developing carbon-based adsorbents that simultaneously deliver high CO 2 adsorption capacity and high selectivity is crucial for energy-efficient carbon capture technologies. To overcome the limitations of conventional activators, we employed potassium chloride (KCl) as a single green salt template and successfully converted sodium lignosulfonate into microporous carbon materials (MCMs) by tailoring the ultramicroporous structure through a molten-salt method. The sample prepared at a KCl-to-sodium lignosulfonate mass ratio of 3:1 exhibited a micropore specific surface area of 1452 m 2 /g, with ultramicropores concentrated in the range of 0.3–0.6 nm. At 0 ℃ and 25 ℃ under 1 bar, the maximum CO 2 adsorption capacities reached 5.04 mmol/g and 3.36 mmol/g, respectively. The CO 2 /N 2 selectivity, estimated by ideal adsorbed solution theory (IAST) under simulated flue gas conditions (15% CO 2 /85% N 2 ) at 25 ℃ and 1 bar, reached 20.2. This outstanding combination of high capacity and high selectivity originates from the substantial micropore volume and the enhanced CO 2 pore wall interactions within the narrow ultramicropores, as evidenced by the low-coverage isosteric heat of adsorption of approximately 29 kJ/mol. This study demonstrates that even with a single potassium chloride salt template, precise control over ultramicropore size distribution can be achieved, enabling both high adsorption capacity and high selectivity, and thus provides a promising candidate for post-combustion CO 2 capture and a sustainable route for the valorization of lignin industrial by-products.

Hydrate-based CO2 sequestration in marine sediments has emerged as a promising strategy to mitigate global climate change due to its substantial storage capacity and operational feasibility. However, understanding the influence of chloride salts from seawater, such as KCl, NaCl, CaCl2, and MgCl2, on CO2 hydrates phase stability is essential for the practical application of subsea CO2 sequestration as hydrates. This study systematically investigates the phase equilibria of CO2 hydrates in KCl, NaCl, CaCl2, and MgCl2 solutions at concentrations of 0–400 mM, encompassing typical marine salinity conditions. The experimental results demonstrate that all four chloride salts exhibit thermodynamic inhibition effects on CO2 hydrates, with the inhibitory effect intensifying as concentration increases. MgCl2 exerts the strongest thermodynamic inhibition effect, suppressing CO2 hydrates equilibrium temperature by 0.96 K at 200 mM and 1.57 K at 400 mM concentrations under 3.0 MPa. The inhibition strength follows the order of MgCl2 > CaCl2 > NaCl > KCl, which correlates well with the ion charge and radius of cations. A thermodynamic model was developed by integrating the Hu-Lee-Sum correlation of water activity with the classical Chen-Guo model for the prediction of the thermodynamic phase equilibria for CO2 hydrates. The proposed model demonstrates high accuracy, with an average absolute deviation of pressure below 2.0% across all tested concentrations. Validation against experimental data and literature values confirms the reliability of the model and serves as a prediction tool for CO2 hydrates phase equilibria with chloride salts. This study advances the understanding of CO2 hydrates thermodynamics in saline systems, elucidating the inhibitory effects of chloride salts and the associated impact on CO2 hydrates stability. The findings provide the thermodynamic foundation for the near-future large-scale adoption of hydrate-based CO2 sequestration.

Effective extraction of lanthanum (La) from spent nuclear fuel is crucial for promoting the sustainable use of nuclear energy. Liquid aluminum (Al) electrode shows significant advantages as active cathodes in the electrochemical extraction of lanthanides (Ln). However, the electrolytic reduction of La by liquid Al in NaCl-KCl melt has not received adequate attention and understanding. For this reason, the electrochemical recovery of La from NaCl-KCl melt using a liquid Al cathode has been investigated in this paper by a series of electrochemical methods. The results indicate that the reduction of La(III) on the W electrode occurs as a one-step process and the reaction is irreversible. The diffusion coefficient of La(III)/La was determined to be 6.70×10 -5 cm 2 s -1 . Meanwhile, the co-reduction process of La(III) and Al(III) on the W electrode was systematically investigated to explore the potential for forming binary intermetallic compounds. In addition, the exchange current density (0.025-0.030 A cm -2 ) at different temperatures was determined using linear polarization (LP), further elucidating the temperature dependence of the exchange current density. Finally, La was successfully extracted as an alloy by potentiostatic electrolysis on the Al electrode. This study provides promising insights for the extraction of La in NaCl-KCl melt on liquid Al electrode.

As the mainstream method for titanium processing, the Kroll process has excessive carbon emissions and high energy consumption due to its reliance on fossil fuels and lengthy semi-continuous process, which not only hinders the implementation of “dual-carbon” goals, but also leads to high production costs. In contrast, molten salt electrolysis achieves direct electrochemical reduction, significantly reducing energy consumption and pollution emissions while reducing costs, in line with the needs of green and sustainable manufacturing. The USTB method represented by soluble anode electrolysis process, is a green and low-cost new process for titanium extraction. However, this method uses NaCl-KCl as the molten salt medium, and faces the problem that it is difficult to control the oxygen content of titanium. In this study, a new method for the preparation of low-oxygen titanium by synergistic electrolysis and thermal deoxidation in NaCl-KCl-YCl 3 was proposed. It can be seen from the thermodynamic calculations that the activity of O 2− in the molten salt can be effectively reduced by the formation of YOCl. Under the equilibrium of Y / YOCl / YCl 3 (Y 3+ (in flux) + O 2- (in flux) + Cl − (in flux) = YOCl), the deoxidation limit is 1000 ppm. The experimental results show that the metal titanium with oxygen content of 700 ppm can be prepared by molten salt electrolysis and thermal deoxidation with TiC x O y as anode, Mo as cathode in NaCl-KCl-YCl 3 molten salt. This work provides a novel strategy for the preparation of low-oxygen titanium based on soluble anode electrolysis.
