Abstract

In this work, the fabrication and experimental study of model Au nanoparticle arrays (nanodots) was used to allow a direct comparison of reactive evaporation at elevated temperatures and nonambient H₂-containing gas atmospheres with theoretical models. Strong temperature and H₂-concentration dependencies were confirmed as expected, and the observed dependence in particle diameter with time was effectively described using a reactive evaporation and gas phase diffusion based quantitative model.

Factors Influencing the Stability of Au-Incorporated Metal-Oxide Supported Thin Films for Optical Gas Sensing

Journal Article Baltrus, John P. ; Holcomb, Gordon R. ; Tylczak, Joseph H. ; ... - Journal of the Electrochemical Society

There is interest in using Au-nanoparticle incorporated oxide films as functional sensor layers for high-temperature applications in optical-based sensors for measurements in both highly-oxidizing and highly-reducing atmospheres at temperatures approaching 900°C-1000°C because of a relatively high melting temperature combined with the inert nature of Au nanoparticles. This study includes a systematic series of experiments and theoretical calculations targeted at further understanding stability of Au-nanoparticle incorporated TiO₂ films as archetype sensing materials. A combination of thermodynamic modeling and long-term exposure tests were utilized to unambiguously determine that gas stream composition-dependent reactive evaporation of Au (to form predominately Au(g) or AuH(g), dependingmore »« less

On the Limited Role of Electronic Support Effects in Selective Alkyne Hydrogenation: A Kinetic Study of Au/MO _x Catalysts Prepared from Oleylamine‐Capped Colloidal Nanoparticles

Journal Article Bruno, James E. ; Sravan Kumar, K. B. ; Dwarica, Nicolas S. ; ... - ChemCatChem

Abstract We report a quantitative kinetic evaluation and study of support effects for partial alkyne hydrogenation using oleylamine‐capped Au colloids as catalyst precursors. The amine capping agents can be removed under reducing conditions, generating supported Au nanoparticles of ∼2.5 nm in diameter. The catalysts showed high alkene selectivity (>90 %) at all conversions during alkyne partial hydrogenation. Catalytic activity, observed rate constants, and apparent activation energies (25–40 kJ/mol) were similar for all Au catalysts, indicating support effects are relatively small. Alkyne adsorption, probed with FTIR and DFT, showed adsorption on the support was associated with hydrogen‐bonding interactions. DFT calculations indicate strong alkyne adsorptionmore »« less

Preparation and catalytic activities for H{sub 2}O{sub 2} decomposition of Rh/Au bimetallic nanoparticles

Journal Article Zhang, Haijun ; The State Key Laboratory of Refractory and Metallurgy, Wuhan University of Science and Technology, Wuhan 430081 ; Deng, Xiangong ; ... - Materials Research Bulletin

Graphical abstract: PVP-protected Rh/Au bimetallic nanoparticles (BNPs) were prepared by using hydrogen sacrificial reduction method, the activity of Rh80Au20 BNPs were about 3.6 times higher than that of Rh NPs. - Highlights: • Rh/Au bimetallic nanoparticles (BNPs) of 3∼5 nm in diameter were prepared. • Activity for H{sub 2}O{sub 2} decomposition of BNPs is 3.6 times higher than that of Rh NPs. • The high activity of BNPs was caused by the existence of charged Rh atoms. • The apparent activation energy for H{sub 2}O{sub 2} decomposition over the BNPs was calculated. - Abstract: PVP-protected Rh/Au bimetallic nanoparticles (BNPs) weremore »« less

Hydrogen evolution promotion of Au‐nanoparticles‐decorated TiO ₂ nanotube arrays prepared by dip‐loading approach

Journal Article Zhang, Dainan ; Chen, Jiahui ; Deng, Peng ; ... - Journal of the American Ceramic Society

Abstract Au nanoparticle (NPs)@TiO ₂ nanotube arrays (NTAs) heterostructured films with enhanced H ₂ generation rate under full spectrum were synthesized, by using a controllable and facile dip‐loading approach. Size of the Au NPs was well‐distributed around 7 nm, and the TiO ₂ NTAs were found vertically aligned. Due to LSPR effect and Schottky contact, the as‐prepared Au NPs@TiO ₂ NTAs heterostructured films exhibited improved H ₂ generation abilities as well as photocatalytic degradation abilities. H ₂ evolution rate of the obtained samples (effective area: 5.25 cm ² ) reached 74.56 μmol/h, which was 38 times higher than that of the raw TiOmore »« less

Role of Au-C Interactions on the Catalytic Activity of Au Nanoparticles Supported on TiC(001) Towards Molecular Oxygen Dissociation

Journal Article Rodriguez, J A ; Feria, L ; Jirsak, T ; ... - Journal of the American Chemical Society

High-resolution photoemission and density functional calculations on realistic slab surface models were used to study the interaction and subsequent dissociation of O{sub 2} with Au nanoparticles supported on TiC(001). The photoemission results indicate that at 150 K O{sub 2} adsorbs molecularly on the supported gold nanoparticles, and upon heating to temperatures above 200 K the O{sub 2} {yields} 2O reaction takes place with migration of atomic oxygen to the TiC(001) substrate. The addition of Au to TiC(001) substantially enhances the rate of O{sub 2} dissociation at room temperature. The reactivity of Au nanoparticles supported on TiC(001) toward O{sub 2} dissociationmore »« less
