The Effect of Molten Salt Composition on Carbon Structure: Preparation of High Value-Added Nano-Carbon Materials by Electrolysis of Carbon Dioxide.

The electrochemical conversion of CO into high value-added carbon materials by molten salt electrolysis offers a promising solution for reducing carbon dioxide emissions. This study focuses on investigating the influence of molten salt composition on the structure of CO direct electroreduction carbon products in chloride molten salt systems. Using CaO as a CO absorber, the adsorption principle of CO in LiCl-CaCl, LiCl-CaCl-NaCl and LiCl-CaCl-KCl molten salts was discussed, and the reasons for the different morphologies and structures of carbon products were analyzed, and it was found that the electrolytic efficiency of the whole process exceeded 85%.

Experimental determination and thermodynamic optimization of the LiF-NdF system.

Neodymium is mainly obtained by electrolysis of a molten LiF-NdF-NdO system. LiF-NdF is a basic system, and the phase diagram of this system provides important information in the production of electrolytic neodymium. An accurate LiF-NdF binary phase diagram helps in the selection of the appropriate molten salt component in production and optimizing the production process, which is of great significance to improve the electrolysis efficiency and reduce the production cost.

Occurrence Behaviors of As/Sb/Bi in Copper Anode Slime and Their Separation by Compound Leaching Followed by Stepwise Precipitation.

Copper anode slime is the main raw material for the extraction of rare and precious metals. However, the recovery of rare and precious metals still faces great challenges due to the variety of impurities and the complex occurrence phase. In view of this, this research focuses on the occurrence mineral phases of arsenic, antimony, and bismuth in copper anode slime, and the process consisting of chloride leaching and selective precipitation of arsenic and bismuth is proposed.
