Single atom metal doped ceria for CO oxidation and HC hydrogenation/oxidation

Steam cracking of ethane, a non-catalytic thermochemical process, remains the dominant means of ethylene production. The severe reaction conditions and energy expenditure involved in this process incentivize the search for alternative reaction pathways and reactor designs which maximize ethylene yield while minimizing cost and energy input. According to the present invention, ethylene yields as high as 68% were obtained with a quartz open tube reactor without the use of a catalyst or a cofed stream of oxidizing agents. The open tube reactor design promotes simplicity, low cost, and negligible coke formation. Reactor designs can be optimized to improve the conversion of ethane to ethylene via non-oxidative dehydrogenation, an approach which shows promise for decentralized production of ethylene from natural gas deposits.

A method of making free-standing ALD-coated plasmonic nanoparticles. The method comprises providing a plurality of semiconductor quantum dots. One or more conformal layers of dielectric material are deposited over the quantum dots to form dielectric-coated quantum dots. A conformal metallic nanoshell is deposited over the dielectric-coated quantum dots to form plasmonic nanoparticles. At least one layer chosen from i) the conformal layers of dielectric material and ii) the conformal metallic nanoshell is deposited using a vapor phase atomic layer deposition (ALD) process. Plasmonic nanoparticles and systems employing the nanoparticles are also disclosed.

The present invention provides for evaporation induced self-assembly (EISA) within microdroplets produced by a vibrating orifice aerosol generator (VOAG) for the production of monodisperse mesoporous silica particles. The process of the present invention exploits the concentration of evaporating droplets to induce the organization of various amphiphilic molecules, effectively partitioning a silica precursor to the hydrophilic regions of the structure. Promotion of silica condensation, followed by removal of the surfactant, provides ordered spherical mesoporous particles.

An aerosol-assisted method for synthesis of nanostructured metallic electrocatalysts and the electrocatalysts formed thereby. The electrocatalyst may be formed from metals such as, but not limited to, platinum, platinum group metals, and binary and tertiary compositions thereof such as, for example, platinum-ruthenium and platinum-tin. The resulting unsupported electrocatalyst is homogenous and highly disperse.
