Chemisorption and reactions of small molecules on small gold particles.
The activity of supported gold particles for a number of oxidations and hydrogenations starts to increase dramatically as the size falls below ~3 nm. This is accompanied by an increased propensity to chemisorption, especially of oxygen and hydrogen. The explanation for these phenomena has to be sought in kinetic analysis that connects catalytic activity with the strength and extent of chemisorp...
متن کاملChemisorption of Arsine on Activated, Impregnated Carbon Adsorbents
This work discusses an ongoing investigation to characterize microporous adsorbents that affect the removal of arsine from air. One aspect of this work was to develop a test system for generating, transport and detection of arsine gas appropriate for adsorbent breakthrough measurements at part-per-billion (ppb) concentrations. Preliminary adsorption data is provided showing the effect of arsine...
متن کاملNonequilibrium activated dissociative chemisorption: SiH4 on Si(100).
A three-parameter local hot spot model of gas-surface reactivity is employed to analyze and predict dissociative sticking coefficients for SiH4 incident on Si(100) under varied nonequilibrium conditions. Two Si surface oscillators and the molecular vibrations, rotations, and translational energy directed along the local surface normal are active degrees of freedom in the 15 dimensional microcan...
متن کاملPhysisorption vs. chemisorption of probe molecules on boron nitride nanomaterials: the effect of surface curvature.
The adsorption of H2O, NH3 and HCOOH as polar probe molecules and C6H6 and CH4 as non-polar ones on a series of zig-zag (n,0) single-walled boron nitride nanotubes (BNNTs) and on a boron-nitride mono-layer (BNML) has been studied by means of B3LYP-D* periodic calculations. Computed electrostatic potential maps for the pristine BN nanomaterials indicate that the smaller the radius, the larger th...
متن کاملCharge Transfer and Chemisorption of Fullerene Molecules on Metal Surfaces: Application to Dynamics of Nanocars
It is widely believed that the dynamics of surface-bound fullerene molecules is not fully understood because current theoretical analyses do not include chargetransfer phenomena. A new theoretical approach to describe charge transfer and chemisorption processes for fullerenes on gold surfaces has been developed. The method is based on extensive semiempirical calculations that provide a consiste...
