PERFORMANCE OF Ce-INCORPORATED KIT-6 SUPPORTED COBALT CATALYSTS FOR FISCHER–TROPSCH SYNTHESIS

Functional Materials Letters (2011)

Guodong Tan Jinlin Li Kong-Yong Liew

A series of Ce -incorporated structure of cubic large mesoporous molecular sieves, KIT-6, with different Ce contents were synthesized by a direct hydrothermal process. A sample of Ce -loaded KIT-6 material was synthesised by incipent wetness impregnation. Similarly, catalysts with 15 wt.% Co loading on the above supports were also synthesized by incipient wetness impregnation. The supports and catalysts were characterized by X-ray diffraction, diffuse reflectance UV-vis, solid-state 29 Si magic-angle spinning nuclear magnetic resonance, H 2 -temperature programmed reduction, H 2 -temperature programmed desorption and oxygen titration. The structure of the KIT-6 support was well retained after Ce incorporation. Small amounts of Ce in the Co catalyst were found to improve the activity and increase the selectivity to C 5+ hydrocarbons for Fischer–Tropsch synthesis, while larger amounts of Ce had the reverse effect. Meanwhile, methane selectivity shows an opposite trend as compared with that of C 5+ selectivity. Ce -loaded KIT-6 supported Co catalyst showed lower activity than KIT-6 supported Co catalyst.

High Alcohols Synthesis via Fischer–Tropsch Reaction at Cobalt Metal/Carbide Interface

ACS Catalysis (2015)

Yanpeng Pei Jin‐Xun Liu Yonghui Zhao Yunjie Ding Tao Liu

Utilization of nonprecious transition metals for high alcohols synthesis is of a great importance in heterogeneous catalysis. We synthesized successfully cobalt metal-carbide (Co–Co2C) catalysts, which present remarkable activity and selectivity for high alpha-alcohols via the Fischer–Tropsch reaction. The formation of the stable cobalt carbide and the Co–Co2C interface are found to be essential for the observed reactivity. Density functional theory calculations show that Co2C is highly efficient for CO nondissociative adsorption, behaving as noble-metal-like, whereas the Co metal is highly active for CO dissociative adsorption and the subsequent carbon-chain growth. The interface between the cobalt metal and its carbide phase, as well as the dual sites available at the interface for facile CO insertion to hydrocarbon, could be used to rationalize the design of the nonprecious transition metal catalysts for the oxygenates in syngas conversion.

Controlled strategy to synthesize SnO2 decorated SnS2 nanosheets with enhanced visible light photocatalytic activity

CrystEngComm (2012)

Xianlong Zhou Tengfei Zhou Juncheng Hu Jinlin Li

Novel SnO2 nanoparticle-decorated SnS2 nanosheets were synthesized via a one-pot solvothermal process using SnCl4·5H2O and CH4N2S as precursors. SnS2@SnO2 nanosheets were characterized by XRD, TEM, FESEM, XPS and UV-vis diffuse reflectance spectra (DRS). The band-gap of SnO2@SnS2 can be easily tuned by the controlled experimental strategy. Anisole and ethanol with different volume ratios were used as binary solvent to tune the composition of SnS2@SnO2 nanocomposites (NCs) continuously and the composites gradually change from hexagonal SnS2 into tetragonal SnO2. All of the SnS2@SnO2 nanosheets exhibited enhanced visible light photocatalytic activity, which was remarkably superior to SnS2, SnO2 and Degussa P-25. The obtained SnS2@SnO2 NCs with Vethanol/Vanisole = 1 : 2 showed the best photocatalytic capability. Furthermore, the formation mechanism of SnS2@SnO2 nanosheets has also been discussed.

Designing Multielement Nanointerfaces in Supported Catalysts by Ultra Small Lattice Mismatch

Zhenteng Sheng Shuai Lyu Xinyue Liu Yuhua Zhang Jinlin Li

Catalysts supported by multiple functional constituents show exceptional catalytic performance, attributed to electron and energy exchanges occurring at the nanointerfaces between different subunits. Herein, the lattice-mismatch mechanism was used to guide the creation of a functional interface between cobalt oxide (CoO) and zinc oxide (ZnO) on a graphene (GN) support. By computing the lattice-mismatch between hexagonal wurtzite CoO (h-CoO) and ZnO, we achieve an exceptionally low value of 0.18%. This ultra small lattice-mismatch facilitates the formation of interfaces when employing a seed-mediated growth approach, using a colloidal method for catalyst design. In this approach, CoO is expected to grow directly on ZnO particles, rather than on GN, when utilizing the ZnO/GN catalyst as heteroseed. The growth pattern of CoO follows the Frank−van der Merwe (FM) model, leading to the successful preparation of ZnO@CoO/GN. Similarly, ZnO readily interfaces with the CoO surface to form a nanointerface when the ZnO@CoO/GN catalyst is used as the seed. Interestingly, this epitaxial growth process can be repeated multiple times, resulting in increasingly diverse nano-heterostructures. The resulting catalyst exhibits outstanding performance in CO2 hydrogenation reaction due to the presence of dense CoO-ZnO nanointerfaces. The methodology presents a novel concept for the advancement of efficient supported catalysts.
