Method for controlling the phosphide-phosphate composition in carbon composites

Abstract

The invention pertains to the field of materials science, specifically to methods for analyzing the chemical composition of carbon composites and monitoring the phosphide and phosphate content in such materials. The objective of the invention is to develop a method for precisely monitoring the phosphide and phosphate content in carbon composites, thereby improving the properties of the materials and expanding their potential uses. The proposed method addresses the complexity and expense of existing analytical methods, while ensuring high accuracy and the ability to directly monitor the composition.The technical result of the invention is the ability to control the phosphide and phosphate ratio during the formation of a carbon composite, increased accuracy of composition regulation by varying the solution concentration, cost-effectiveness and applicability in industrial settings, ease of implementation and the possibility of scaling the process, and reduced need for expensive equipment and qualified personnel. This technical result is achieved by controlling the phosphide-phosphate composition in carbon composites by varying the concentration of the initial solution. This is accomplished by varying the solution concentration by adjusting the mass of the water-soluble polymer used as the electrospinning matrix and carbon source, the mass of the salt (the transition metal source), and the volume of phosphoric acid (the phosphorus source).Varying the solution concentration during electrospinning allows for control of the solution viscosity and the conditions for nanostructure formation, which influences the distribution of phosphides and phosphates in the final composite. Increasing the concentration can increase the phosphide content, while decreasing it can increase the phosphate content, enabling precise control of the chemical composition of the material.
