摘要：

In this paper we present our results obtained on tuning the synthesis parameters for obtaining pure mesoporous silica of SBA-15 type. We have investigated the influence of NaCl added in the reaction mixture (in different quantities) and the role of the synthesis temperature and hydrothermal treatment on the properties of the final siloxanic material. In well established conditions we have obtained five different mesoporous materials (S1-S5) from which S4 has high quality (527 m(2)/g specific surface area and 0.5 cm(3)/g pore volume).
