Infrared spectra of methanol desorption in a He stream and under vacuum on CeO₂ and ZrO₂ catalyst surfaces

RSC Advances (2016)

Lei Chen Shengping Wang

Infrared spectra of methanol desorption in a He stream and under vacuum on CeO₂ and ZrO₂ catalyst surfaces are added for the article (RSC Adv., 2014, 4, 30968) as a response to the letter of Dr F. C. Meunier (RSC Adv., 2016, 6, 17288) and to make the ascription of the bands at 1096, 1054, 1032 and 1012 cm⁻¹ more convincing.

Catalytic Combustion of Methane over Noble Metal Catalysts

ACS Catalysis (2024)

Huimei Duan Fanxin Kong Xinze Bi Lei Chen Hangrong Chen

As one of the cleanest fossil fuel resources, methane is also the second largest greenhouse gas after CO2 owing to its strong greenhouse effect. The direct emission of large quantities of trace and unburned methane causes a serious energy loss and greenhouse effect. Catalytic methane combustion is a promising strategy in eliminating methane slip to address the urgent environmental issue. However, the current methane abatement catalysts still face great challenges in thermal stability, water resistance, and sulfur tolerance. In this review, we focus on the popular noble metal-based catalysts, discuss the distinct reaction mechanisms including the Langmuir–Hinshelwood model, Eley–Rideal model, Mars–van Krevelen model, and two-term mechanisms. The deactivation mechanisms induced by sintering, sulfur, and water on popular Pd-based catalysts are then analyzed. Then, we outline the promotion strategies from two aspects, i.e., construction of a core–shell structure and electronic engineering of the active phase to improve thermal stability and poisoning resistance. Finally, a summary and prospects with an emphasis on the newly developed oxide-metal interfaces and photothermal catalysis for highly efficient methane combustion are addressed.

Tungsten-Embedded Graphene: Theoretical Study on a Potential High-Activity Catalyst toward CO Oxidation

Materials (2018)

Guoliang Dai Lei Chen Xin Zhao

The oxidation mechanism of CO on W-embedded graphene was investigated by M06-2X density functional theory. Two models of tungsten atom embedded in single and double vacancy (W-SV and W-DV) graphene sheets were considered. It was found that over W-SV-graphene and W-DV-graphene, the oxidation of CO prefers to Langmuir-Hinshelwood (LH) and Eley-Rideal (ER) mechanism, respectively. The two surfaces exhibit different catalytic activity during different reaction stages. The present results imply that W-embedded graphene is a promising catalyst for CO oxidation, which provides a useful reference for the design of a high-efficiency catalyst in detecting and removing of toxic gases.

A first principles study of water dissociation on small copper clusters

Physical Chemistry Chemical Physics (2010)

Lei Chen Qingfan Zhang Yunfeng Zhang Winston Z. Li Bo Han

Water dissociation on copper is one of the rate-limiting steps in the water-gas-shift (WGS) reaction. Copper atoms dispersed evenly from freshly made catalyst segregate to form clusters under the WGS operating conditions. Using density functional theory, we have examined water adsorption and dissociation on the smallest stable 3-dimensional copper cluster, Cu(7). Water molecules are adsorbed on the cluster sequentially until full saturation at which no direct water-copper contact is sterically possible. The adsorption is driven mainly by the overlap between the p-orbital of O atom occupied by the lone pair and the 3d-orbitals of copper, from which a fractional charge is promoted to the 4s-orbital to accommodate the charge transfer from water. Water dissociation on the Cu(7) cluster was investigated at both low and high water coverage. It was found that water dissociation into OH and H is exothermic but is inherently a high temperature process at low coverage. At high coverage, the reaction becomes more exothermic with fast kinetics. In both cases, water can catalyze the reaction. It was found that direct dissociation of the OH species is endothermic with a significantly higher barrier at both low and high coverage. However, the OH species can readily react with another adjacent hydroxyl group to form an O adatom and water molecule. Our studies indicate that the basic chemical properties of water dissociative chemisorption may not change significantly with the size of small copper clusters. Similarities between water dissociation on copper clusters and on copper crystalline surfaces are discussed.
