In this paper, nanocomposite La₂Ti₂O₇-Zeolite-MCM-41is synthesized by optimization of physical properties of MCM-41Zeolite and Nano powder La₂Ti₂O_7  sol-gel method in stearic acid media. In the first step, the La₂Ti₂O₇Nano power- was prepared by sol-gel process and then nanocomposites of La₂Ti₂O₇-Zeolite-MCM-41 with (5,10,15 and 20) percent weight. Then we have prepared of sol-gel at 700-900 and 1000 and for further confirmation of structure used of x-ray and XRD.

Result of SEM, the size of the La₂Ti₂O₇Nano powder (29nm) and nanoparticles in nanocomposite La₂Ti₂O₇-Zeolite-MCM-41 20%, (29nm) were shown EDX the purification of nanoparticles and nanocomposite are convenient.

The BET method was showed the differential porosity value in comparison of zeolite and nanocomposite La₂Ti₂O₇-ZMCM-41 the calcination condition, weight percent nanoparticles, the type of reagents PH and indicator concentration are influenced on nanocomposite.

Properties by optimization of mentioned parameters, the best results for 10% and 20% nanocomposite in 900 temperature calcination with (29 nm) particle size are yield. The UV methylene blue in 80 and 100% are out come respectively. All results were confirmed by spectroscopies data.
