Metallic ruthenium incorporation in the porous structure of SBA-15 using a sonochemical method

Abstract

Ultrasonic waves are employed for the first time to incorporate ruthenium into the pore structure of SBA-15. The resultant materials were analyzed by X-ray diffraction (XRD), nitrogen adsorption, transmission electron microscopy (TEM) and Raman measurements. Only microporous channels of SBA-15 are confirmed to be filled with ruthenium, leaving the mesopores unaffected. Therefore, high surface area and ordered structure are maintained after the incorporation of ruthenium nanoparticles in the porous structure of SBA-15.
