Synthesis of nanosized platinum cluster in cubic mesoporous material via a direct introduction method



Platinum‐cluster‐containing cubic mesoporous material (Pt‐MCM‐48) has been synthesized by direct introduction of chloroplatinic acid during the synthesis of MCM‐48. In addition, we have also studied the incipient wetness impregnation and ion‐exchange method to obtain the platinum‐containing cubic mesoporous material. The nature of the platinum‐MCM‐48 catalyst has been characterized by different techniques such as XRD, N2 adsorption, TEM, XPS, and NMR. The catalyst obtained by direct introduction of platinum in the synthesis gel shows higher activity in the hydrogenation of benzene and toluene.
