Ultrasonic-assisted synthesis of hollow mesoporous silica as a toxic gases suppressant

Abstract Here, we present a facile ultrasonic-assisted method to fabricate hollow mesoporous silica spheres. The prepared hollow mesoporous silica spheres own well-regulated size, large specific surface area, and homogeneous mesoporous. Time-dependent experimental results depict that the formation of the hollow spheres undergoes a selective etching process. The results of fire toxic tests show that the toxic gases decomposed from the combustion of epoxy resin were observably inhibited with the incorporation of hollow mesoporous silica.
