摘要: The deposition of gold on silica tends to give large particles when using conventional techniques. We report the preparation 0.8 ± 0.2 nm a modified SBA-15 support. method involves functionalization with amine groups and at basic pH. These catalysts are highly active selective in dehydrogenation formic acid.
