Growth of MOFs on different solid surfaces is very interesting in increasing their mechanical properties. Silica is a potential candidate as a MOF substrate in order to increase their resistance. Due to difficulty of rising H-KUST MOF on silica substrate our group was motivated to achieve a successful coating. This work outlines the functionalization of the surface of gold through the self-assembled monolayer (SAM) technique and the construction of a metal-organic framework (MOF) film of H-KUST-1. This MOF was also grown onto modified mesoporous SBA-15 silica. The silica particles were previously conformed and activated to receive the MOF. The layer-by-layer and in situ crystallization methods were evaluated and compared. The deposited MOFs were characterized for their uniformity and crystallinity using X- ray diffraction, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), and scanning probe microscopy (AFM). This project also contributes scientifically and technologically to the knowledge in the field of functionalized hybrid materials with great potential for industrial applications.
