Methods of making graphene oxide and reduced graphene oxide are provided. The methods can include a simple one-pot synthesis of graphene oxide from a purified coal powder using a mild oxidizing acid. The methods provide for an improved, more cost-effective, and simpler process than conventional methods such as Hummers methods. In some aspects, placing the purified coal powder in the mild oxidation atmosphere includes contacting the purified coal powder with a mild oxidizing acid such as nitric acid, nitrous acid, sulfuric acid, phosphoric acid, benzoic acid, or a combination thereof. In some aspects, the mild oxidizing acid consists essentially of nitric acid. Graphene oxides and reduced graphene oxides prepared by the methods are also provided.

The present invention provides a cerium dioxide-supported low-dose PtCu ultrafine alloy catalyst, a preparation method and an application thereof, which belongs to the fields of environmental catalysis and preparation of catalyst materials. Metal-state PtCu ultrafine alloy particles are prepared by an oleylamine method, and then a cerium dioxide support is immersed into an n-butylamine solution of PtCu ultrafine alloy, centrifuged, washed with alcohol, and dried to obtain the cerium dioxide-supported low-dose PtCu ultrafine alloy catalyst. The catalyst obtained has excellent activity and stability in simultaneously degrading atmospheric VOCs and soot under a photothermocatalytic condition. There are the characteristics of simple preparation process method, very low Pt dosage, high utilization rate, and excellent photothermocatalytic performance.
