AI Technical Summary

Technical Problem

Existing uranium extraction and processing technologies suffer from problems such as narrow light response, rapid carrier recombination, limited single-field catalytic efficiency, poor controllability of material preparation, and mismatch between materials and application scenarios, making it difficult to efficiently remove and recycle uranyl ions in complex aquatic environments.

Method used

Using MnPX3 piezoelectric-photocoupled catalytic material, mechanical energy perturbation is applied under visible light irradiation. By utilizing the piezoelectric-photosynergistic effect, soluble U(VI) is efficiently reduced to insoluble U(IV) precipitate, and uranium removal and recovery are achieved through solid-liquid separation.

Benefits of technology

This method achieves efficient reduction of U(VI) to U(IV) in aqueous solution under the combined action of visible light and mechanical energy, breaking through the bottleneck of the single energy utilization form and easy recombination of charge carriers in existing catalytic materials, and providing a material system with high efficiency, stability and excellent selectivity for uranium water treatment.

Abstract

This invention relates to the application of MnPX3 piezoelectric-photocoupled catalytic material in uranium extraction from water, belonging to the field of functional materials and radioactive uranium extraction and remediation technology. The MnPX3 piezoelectric-photocoupled catalytic material is added to water containing radioactive uranium (U(VI)). Under visible light irradiation, mechanical energy perturbation is applied, and utilizing the piezoelectric-photosynergistic effect, soluble U(VI) is efficiently reduced to insoluble U(IV) precipitate. Uranium removal and recovery are achieved through solid-liquid separation. This invention, through a piezoelectric-photocoupled dual-field mechanism, successfully overcomes key technical bottlenecks of existing catalytic materials, such as limited energy utilization, easy carrier recombination, and poor adaptability to complex water bodies. It provides a new material system and technical path with high efficiency, stability, excellent selectivity, and large-scale application potential for uranium-containing water remediation and uranium resource recovery.
