Organized Pd nanoparticles into the hybrid framework of S- and/N-Rich Thiadiazole/Thiocarbamate bridged periodic mesoporous organosilica

The nanoscale porosity and high surface area of periodic mesoporous organosilica (PMO) contribute to enhanced dispersion of active sites, notably increasing their applicability in various fields, including catalysis. Here, a novel PMO material TdTc-PMO rich in S- and N-, containing thiadiazole and thiocarbamate (TdTc) bridge within its pore wall has been successfully synthesized. TdTc-PMO displays remarkable properties such as highly ordered 2D-hexagonal nanostructure, high surface area (527 m 2 g ‐1 ), and act as good hub for 1transition metals, such as PdNPs. By in situ depositing Pd nanoparticles into the mesochannels to produce a heterogeneous catalyst, the resulting material exhibits outstanding catalytic activity in the reduction of the water pollutant 4-nitrophenol.
