A new layered graphite oxide is synthesized by a two-step oxidation of commercial graphite powders, which is further covalently modified by a titanium complex in order for oxidation of alkenes. Characterizations reveal the present graphite oxide is thicker than classical graphene oxide, but shows fibrous morphology after modification of titanium complex. Furthermore, the composition and morphology of synthetic composite are highly relative to the heating condition in preparation. In catalysis, high conversions of alkenes as well as various oxidized products are obtained by using available and green terminal oxidants. Lastly, a composite catalyst is reused for nine rounds in oxidation of R-(+)-limonene, approving its satisfactory stability for recycling. This work provides a highly promising catalytic material, showing values for the design of solid catalysts.
