Multi-Walled Carbon Nanotubes as a Novel Promoter of Catalysts for CO/CO2 Hydrogenation to Alcohols

Abstract

Multi-walled carbon-nanotubes (MWCNTs) are drawing increasing attention in recent years. This material possesses a series of unique features, such as its nanometer-sized channel, highly conductive graphitized tube-wall, sp (2)-C-constructed surface, and excellent performance for adsorption and spillover of hydrogen, which make the MWCNTs full of promise to be a novel catalyst support or promoter. This article will review the recent progress in applied research of MWCNTs as a novel promoter in heterogeneous catalysis for active components, including metals and their oxides, with the emphasis on the study and development of MWCNT-promoted catalysts related to CO/CO2 hydrogenation to alcohols and dimethyl ether based on the recent works carried out in our laboratory.National Natural Science Foundation [20590364]; National Basic Research ("973") of China [2005CB221403, 2009CB939804

Nanostructured Carbon–Metal Oxide Hybrids as Amphiphilic Emulsion Catalysts

“…[10][11][12][13][14] Specifically, in the field of heterogeneous catalysis, CNTs have been used as catalytic materials, [15][16][17][18] catalyst supports, [19] and catalyst promoters. [20] Nanotubes exhibit several promising features for catalysis including very high surface area, high resistance to temperature in non-oxidizing environments, and acidic and basic environments, as well as surface reactivity and chemical tunability, achieved by functionalization.…”

Performance of Gold Nanoparticles Supported on Carbon Nanotubes for Selective Oxidation of Cyclooctene with Use of O2 and TBHP

“…On the other hand, multi-walled carbon nanotubes (CNTs), a kind of nano-carbon materials, have been drawing increasing attentions for catalytic applications [26][27][28][29][30]. This type of nanotube-C possesses medium to high specific surface areas, in addition to several unique features, such as graphitized tube-wall, nanometer-sized channel and sp 2 -C-constructed surface.…”

Recent Advances in Catalytic/Biocatalytic Conversion of Greenhouse Methane and Carbon Dioxide to Methanol and Other Oxygenates

“…Very recently, Zhang et al (Zhang et al, 2009) reported that carbon nanotubes (CNTs) or CNT-based materials doped with some transition metals such as Co, Pd, etc., exhibited good catalytic activity and selectivity for some catalytic processes related to adsorption-activation and spillover of hydrogen such as CO or CO 2 hydrogenation to alcohols. However, further detailed investigations of the interactions between CNTs and catalytically active host components and between CNTs and reactant molecules are needed in order to gain a better understanding of the nature of the promoter action by CNTs (Zhang et al, 2009).…”
