Single-site gallium centers, obtained via grafting of a molecular siloxide precursor on the surface of partially dehydroxylated silica followed and a thermal transformation, display high initial activity for propane dehydrogenation, (TOF 20 mol C3H6 per mol Ga per h), and high selectivity for propylene (≥93) over 20 h.
