Description of supported metal structure sensitivity by a geometric approach

چکیده

A series of Pt/Al2O3 catalysts with uniform Pt particle sizes ranging from 0.95 to 2.62 nm was synthesized using the refilling method control growing nanoparticles and evaluated in propane dehydrogenation. An effect size on initial activity TOF demonstrated, smallest particles being most active. geometric model developed quantify surface site concentration for any fcc metal size. Comparing evolution dehydrogenation different concentrations, it shown that active sites corresponded combination corner edge atoms. To get further, confronted numerous data extracted literature demonstrating is an efficient tool predict structure–activity relationship determine exact nature a wide range reactions metals.

conceptual metaphor and the acquisition of english metaphorical competence by persian english majors: a cognitive linguistic approach

بنا براستدلال زبانشناسان شناختی ، اندیشه آدمی تا حدّ زیادی استعاری است: ما اندیشه ای را، و یا قلمرو مفهومی معیّنی را، بر حسب اندیشه و یا قلمرو مفهومی معیّن دیگری درک ویا تجربه می کنیم. موارد این نوع اندیشیدن ، که استعارات مفهومی خوانده می شوند، در زبان های گوناگون به صورت تعبیرات استعاری واقعیّت می یابند. به گمان بعضی از پزوهشگران زبان دوم، آموزش وفراگیری این گونه تعبیرات باید بخشی لازم از برنامه ه...

Geometric and electronic structure of a peroxomanganese(III) complex supported by a scorpionate ligand.

A monomeric Mn(II) complex has been prepared with the facially-coordinating Tp(Ph2) ligand, (Tp(Ph2) = hydrotris(3,5-diphenylpyrazol-1-yl)borate). The X-ray crystal structure shows three coordinating solvent molecules resulting in a six-coordinate complex with Mn-ligand bond lengths that are consistent with a high-spin Mn(II) ion. Treatment of this Mn(II) complex with excess KO2 at room tempera...

Microstructural stability of supported metal catalysts: A phase field approach

The long-term stability of supported metal catalysts designed for solid-oxide fuel cell (SOFC) anodes is evaluated using a phase field simulation approach. Porous support structures are numerically sintered and then infiltrated with a nanoscale catalyst phase to mimic scaffolds fabricated via both pyrolysis and acid leaching techniques. Simulations capture the dewetting, particle agglomeration,...

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...

Growth and structure of supported metal catalyst particles

The applications of supported metal catalysts vary widely, from selective hydrogenation in the fine chemicals industry to the control of vehicle emissions. Yet many basic questions about the structure, activity, and durability of these catalysts remain unanswered. For example, there is still much uncertainty about the mechanism of metal particle growth, or sintering, which is a major cause of c...
