Application
3-Mercaptopropyl-functionalized silica gel (MPS) is a resin which can be used:
- As a binding agent in diffusive gradients in thin film (DGT) technique for the determination of labile Hg, methylmercury and arsenic (AsIII) concentrations.
- As a heterogeneous support for immobilizing titanocene catalysts for hydrosilylation of 2-phenylpyrroline.
- As a reducing agent for sulfoxide deoxygenation.
- As a metal scavenger for various metals such as Pd, Pt, Cu, Ag and Pb.

The functionalization of SBA-15 with mercaptopropyl trimethoxysilane leads to a material capable of absorbing Pd from organic and aqueous solutions. The resulting Pd-loaded material acts as a catalyst for the Suzuki-Miyaura and Mizoroki-Heck coupling reactions. Leaching studies show that the
