ABSTRACT:
The invention relates to Group 1 metal/silica gel compositions comprising silica gel and an alkali metal or alloy, wherein Group 1 metals or alloys are absorbed into the silica gel pores. The invention relates to producing hydrogen gas comprising contacting a Group 1 metal/silica gel composition with water, and further relates to an alkali metal reduction of an organic compound, the improvement comprising contacting the organic compound with a Group 1 metal/silica gel composition. In these embodiments, the Group 1 metal/silica gel composition reacts with dry O2. The invention also relates to producing hydrogen gas comprising contacting a Group 1 metal/silica gel composition with water, and further relates to an alkali metal reduction of an organic compound, the improvement comprising contacting the organic compound with a Group 1 metal/silica gel composition. In these embodiments, the Group 1 metal/silica gel composition produced does not react with dry O2.
