Graphene oxide, a two-dimensional aromatic scaffold decorated by oxygen-containing functional groups, possesses rich chemical properties and may present a green alternative to precious metal catalysts. Graphene oxide-based carbocatalysis has recently been demonstrated for aerobic oxidative reactions. However, its widespread application is hindered by the need for high catalyst loadings. Here we...

Emerging characteristics upon nitrogen-doping were differentiated in the activation of superoxides over single-walled carbon nanotubes. Both experimental and theoretical studies revealed that enhanced peroxymonosulfate (PMS) activation is ascribed to a nonradical process while persulfate (PS) activation is accelerated via directly oxidizing water, yet hydrogen peroxide (H2O2) activation is iner...

Benzaldehyde (BzH) is an important chemical for industrial feedstock. However, the conventional production processes heavily rely on precious metal catalysts and bring about unavoidable pollution issues. Here we report a new catalytic process to use N-doped graphene oxide (NGO) as catalyst oxidation of benzyl alcohol (BzOH) into BzH by environmentally benign oxidant, peroxymonosulfate (PMS). Di...

Carbon catalyst consisting of a hybrid structure made up of amorphous carbon and nanographite was prepared from the leaves of Pinus Roxburghii. The catalyst was prepared through sodium hydroxide and hydrochloric acid treatment of the dried pine leaves; and further functionalized with sulfuric acid treatment to incorporate the acidic functionalities. The synthesized catalyst was characterized by...
