摘要： A method for the preparation of graphene is provided, which includes: (a) oxidizing a graphite material to form graphite oxide; (b) dispersing graphite oxide into water to form an aqueous suspension of graphite oxide; (c) adding a dispersing agent to the aqueous suspension of graphite oxide; and (d) adding an acidic reducing agent to the aqueous suspension of graphite oxide, wherein graphite oxide is reduced to graphene by the acidic reducing agent, and graphene is further bonded with the dispersing agent to form a graphene dispersion containing a surface-modified graphene. The present invention provides a method for the preparation of graphene using an acidic reducing agent. The obtained graphene can be homogeneously dispersed in water, an acidic solution, a basic solution, or an organic solution.

摘要： A self-propagating combustion cyclone reactor includes a reaction chamber delimited by a circumferential wall in which at least one reductant inlet and a plurality of oxidizer inlets are formed in a tangential manner. Reductant and oxidizer are fed, together with inert gas, through the inlets into the chamber in a cyclonic manner to induce self-propagating combustion reaction to generate a product of high purity metal, such as titanium, zirconium, hafnium, or silicon, semiconductor substance. The reactor serves as a continuous reactor for generation of metal or semiconductor substances of high purity.
