This perspective article critically reviews the catalysis literature on the nature of the surface CrOx sites present on SiO2 in different environments. The recent application of in situ spectroscopic techniques that directly monitor the surface chromia sites on silica in different environments has significantly improved our fundamental understanding of supported CrOx/SiO2 catalysts.
