<p>The work presented in this thesis has been focus on developing the idea of mesoreactor based on mesoporous silica SBA-15. SBA-15 is a mesoporous material with highly ordered pore structure and tailorable pore sizes with narrow sizes distribution. SBA-15 has been utilized to provide reaction sites for electroless copper deposition and the support of the synthesized copper nanoparticles. Oxidation processes have been conducted in order to improve the weak ion-exchange capability of as-synthesized silica surfaces. The efficiency of oxidation processes have been studied through various oxidizing agents and time. The surface treatments of mesoporous silica have been proofed to affect the distribution of the nanoparticles. Copper nanoparticles of 5 nm with narrow size distribution have been synthesized without the use of any capping agents and are homogeneously embedded in the silica matrix.</p>
