  • Abstract Titanosilicalite-1 (TS-1) was first treated with aqueous KOH solution to introduce surface defects. Then KOH-treated TS-1 (TS-1K) was further treated with aqueous HNO 3 solution to remove residual potassium. Then, Au was deposited by solid grinding on this support free of K (TS-1KH) as 1.6 nm clusters, which could be stabilized by surface detects. Finally, Au/TS-1KH was modified by impregnating potassium salts, alkali hydroxides or alkaline earth metal acetates. XRD and UV–vis spectra… CONTINUE READING
