Optimization of LiFePO4 synthesis by hydrothermal method

tailieu.vn

Lithium iron phosphate may be produced through methods of solid state synthesis, mechanical- or spray- drying, sol-gel, and hydrothermal synthesis. Hydrothermal synthesis was shown to be useful in obtaining small- sized fine particles. however, in an effort to reduce costs and energy usage it was demonstrated in 2001 that hydrothermal synthesis can indeed be used to synthesize lithium iron phosphate at the low temperature of 120 ◦ C, which made. hydrothermal synthesis a favorable option.

The hydrothermal synthesis of blue-emitting boron-doped CQDs and its application for improving the photovoltaic parameters of organic solar cell

tailieu.vn

Herein, boron doped CQDs synthesis was achieved by hydrothermal method to use as an additive into the P3HT:PCBM blend. B-CQDs were introduced with various volumes into P3HT:PCBM blend to improve energy harvesting properties, crystal structure, and charge transport properties of photoactive layer. The results showed that the morphological and optical properties of P3HT:PCBM films and its crystallinity improved after the addition of B-CQDs.

SO2 sorption properties of fly ash zeolites

tailieu.vn

Zeolites synthesized for the process of SO 2 removal were obtained via hydrothermal fly ash synthesis with an aqueous solution of sodium hydroxide. Hydrothermal synthesis of fly ash zeolites is recognized as a process of fly ash conversion in the presence of an alkaline solution into zeolites. In the hydrothermal synthesis, in the presence of OH. the Si and Al components are dissolved from the fly ash. This crystal structure is formed in the presence of Na + cations.

Syntheses and photoluminescence properties of new Zn(II) and Cd(II) coordination polymers prepared from 5-sulfoisophthalate ligand

tailieu.vn

In the synthesis of coordination polymers, conventional synthesis, solvothermal/hydrothermal, microwave-assisted, sonochemical, electrochemical, and mechanochemical methods have been applied. 10 Among these methods, solvothermal/hydrothermal synthesis is the most important and common tool to obtain new, highly robust, and extended coordination polymers in single crystal form. 5-Sulfoisophthalic acid (sipH 3 ) is one such interesting ligand and has two functional groups, –SO 3 H and –COOH.
