Abstract: The present disclosure is directed to methods for producing metal oxynitrides using flame synthesis. Embodiments of the disclosure may provide advantages over prior synthesis techniques by reducing synthesis time. Additionally, methods and systems disclosed herein may achieve better incorporation of nitrogen atoms into the oxide structure due in part to the higher homogeneity of flame made particles and ability to control the reaction environment.

Abstract: The present disclosure relates to yolk-shell structured catalysts having compositions that can be particularly useful in the dry reforming of methane. These catalysts can demonstrate long-term stability that would be an advantage in industrial applications such as mitigating fossil fuel plant emissions. Example catalysts can include a yolk containing nickel (Ni) or nickel oxide (NiO), platinum (Pt) or platinum oxide (PtO2), and a third material (M3) such as a cerium oxide (CeOx). The shell can be formed of a ceramic such as silica and is generally a porous material that can support the yolk.

Abstract: Methods for deriving a low-C hydrocarbon fuel from a platform chemical mixture are provided by introducing the platform chemical mixture to a catalytic material to produce a product stream comprising the low-C hydrocarbon fuel, and separating the low-C hydrocarbon fuel in the product stream from any remaining platform chemicals. Methods for producing aromatic hydrocarbons benzene, toluene, and xylenes from a platform chemical mixture are also provided by introducing a catalytic material to the platform chemical mixture to produce a immiscible liquid product stream comprising BTX, and separating the BTX in the liquid product stream from unreacted platform chemicals via a decanting process.

Abstract: The present disclosure relates to yolk-shell structured catalysts. The yolk-shell catalysts can be particularly useful in the tri-reforming of methane. The yolks can include a primary material (M1), such as nickel (Ni) or nickel oxide (NiO), and a secondary material (M2). The shell is generally a porous material that can support the yolk. The shell can include silica (SiO2) and the secondary material can include ceria (CeO2). The yolk-shell catalyst can take the form of tube-like structures in which the yolk is dispersed within the shell support in a substantially homogeneous fashion.
