Rational Design of Colloidal Noble Metallic and Bimetallic Nanocatalysts and Development of a Microfluidic Reactor Platform for Fundamental Assessment of Catalytic Activity

Multi-phase catalytic hydrogenations play a significant role in converting bio-derived materials to commodity chemicals and liquid fuels. It is desirable to conduct the reaction efficiently, economically and in an environmentally-friendly manner to achieve the goals of green chemistry. However, mass transfer limitations and harsh reaction conditions often interfere with the assessment of intrin...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

Interface engineering for a rational design of poison-free bimetallic CO oxidation catalysts.

We use density functional theory calculations of Pt@Cu core@shell nanoparticles (NPs) to design bifunctional poison-free CO oxidation catalysts. By calculating the adsorption chemistry under CO oxidation conditions, we find that the Pt@Cu NPs will be active for CO oxidation with resistance to CO-poisoning. The CO oxidation pathway at the Pt-Cu interface is determined on the Pt NP covered with a...

Structural Changes of Bimetallic PdX/Cu (1-X) Nanocatalysts Developed for Nitrate Reduction of Drinking Water

Reductive removal by hydrogeneration using supported Pd/M (M= Cu, Pt, Ag, Co, Fe, Mo, Ni, Rh, Ir, Mn and Cr) bimetallic catalysts has emerged as a promising alternative for nitrate removal in drinking water [1]. Fundamental understanding how the atomic arrangement of Pd and a second element, such as Cu, affect the activity nitrite reduction and selectivity of dinitrogen will be accomplished by ...
