The simple and easy spin coating technique is applied here to make homogeneous thin films. The surface characterization using FESEM shows crack-free films with a perpendicular pore arrangement. The applicability of these thin films as catalysts as well as a robust SERS active substrate for model catalysis study is tested. Compared to bare silica film our gold incorporated silica, GSM-23F gave an enhancement factor of 10(3) for RhB with a laser source 633 nm. The reduction reaction of p-nitrophenol with sodium borohydride from our thin films shows a decrease in peak intensity corresponding to -NO2 group as time proceeds, confirming the catalytic activity. Such model surfaces can potentially bridge the material gap between a real catalytic system and surface science studies.</p>10agold nanoparticles10amodel catalysis10aSERS10aThin films1 aSekhar, Anandakumari, Chandrasek1 aVinod, Chathakudath, Prabhakara  uhttps://library.ncl.res.in/content/gold-incorporated-mesoporous-silica-thin-film-model-surface-robust-sers-and-catalytically
