Abstract: Apparatus and processes for high-yield production of syngas components via combustion of a carbon-containing material and an oxygen-containing material are provided. Syngas components are generated in an exothermic, combustion reaction with only minor quantities of carbon dioxide, water, and elemental carbon produced.

Abstract: Methods of preparing graphene/graphene oxide particulates under mild conditions, comprising reacting pristine graphene with hydrogen peroxide and a source of iron to oxidize the outer surface of the pristine graphene particulates in solution and yield graphene/graphene oxide particulates. Methods and articles incorporating the same are also disclosed.

Abstract: Apparatus and methods are provided that are capable of mass production of particulate materials, such as graphene particulates. The apparatus comprises an ignition assembly that comprises readily interchangeable electrode cassettes and that may be configured to self-clean in between the combustion cycles in which the particulate materials are generated. Methods of generating the particulate materials require low energy inputs in order to initiate the combustion reaction, which is then self-sustaining until the reactants are depleted.

Abstract: A method of producing pristine graphene particles through a one-step, gas-phase, catalyst-free detonation of a mixture of one or more carbon-containing compounds hydrocarbon compounds and one or more oxidizing agents is provided. The detonation reaction occurs very quickly and at relatively high temperature, greater than 3000 K, to generate graphene nanosheets that can be recovered from the reaction vessel, such as in the form of an aerosol. The graphene nanosheets may be stacked in single, double, or triple layers, for example, and may have an average particle size of between about 35 to about 250 nm.

Abstract translation: 提供了通过一步，气相，无催化剂的一种或多种含碳化合物的混合物的烃类化合物和一种或多种氧化剂的混合物生成原始石墨烯颗粒的方法。 爆炸反应非常快速地发生，并且在相对较高的温度下大于3000K，以产生可从反应容器中回收的石墨烯纳米片，例如以气溶胶的形式。 石墨烯纳米片可以例如以单层，双层或三层层叠，并且可以具有约35至约250nm的平均粒度。
