New nanostructured sorbents for desulfurization of natural gas

Lifeng WANG, Ralph T. YANG

Frontiers of Chemical Science and Engineering 2014, Volume 8, Issue 1, Pages 8-19 doi: 10.1007/s11705-014-1411-4

Abstract: Desulfurization of natural gas is achieved commercially by absorption with liquid amine solutions. Adsorption technology could potentially replace the solvent extraction process, particularly for the emerging shale gas wells with production rates that are generally lower than that from the large conventional reservoirs, if a superior adsorbent (sorbent) is developed. In this review, we focus our discussion on three types of sorbents: metal-oxide based sorbents, Cu/Ag-based and other commercial sorbents, and amine-grafted silicas. The advantages and disadvantages of each type are analyzed. Possible approaches for future developments to further improve these sorbents are suggested, particularly for the most promising amine-grafted silicas.

Structural engineering of transition metal-based nanostructured electrocatalysts for efficient water

Yueqing Wang, Jintao Zhang

Frontiers of Chemical Science and Engineering 2018, Volume 12, Issue 4, Pages 838-854 doi: 10.1007/s11705-018-1746-3

Abstract: Water splitting is a highly promising approach for the generation of sustainable, clean hydrogen energy. Tremendous efforts have been devoted to exploring highly efficient and abundant metal oxide electrocatalysts for oxygen evolution and hydrogen evolution reactions to lower the energy consumption in water splitting. In this review, we summarize the recent advances on the development of metal oxide electrocatalysts with special emphasis on the structural engineering of nanostructures from particle size, composition, crystalline facet, hybrid structure as well as the conductive supports. The special strategies relay on the transformation from the metal organic framework and ion exchange reactions for the preparation of novel metal oxide nanostructures with boosting the catalytic activities are also discussed. The fascinating methods would pave the way for rational design of advanced electrocatalysts for efficient water splitting.

Modeling nanostructured catalyst layer in PEMFC and catalyst utilization

Jiejing ZHANG, Pengzhen CAO, Li XU, Yuxin WANG

Frontiers of Chemical Science and Engineering 2011, Volume 5, Issue 3, Pages 297-302 doi: 10.1007/s11705-011-1201-1

Abstract: A lattice model of the nanoscaled catalyst layer structure in proton exchange membrane fuel cells (PEMFC) was established by Monte Carlo method. The model takes into account all the four components in a typical PEMFC catalyst layer: platinum (Pt), carbon, ionomer and pore. The elemental voxels in the lattice were set fine enough so that each average sized Pt particulate in Pt/C catalyst can be represented. Catalyst utilization in the modeled catalyst layer was calculated by counting up the number of facets of Pt voxels where “three phase contact” are met. The effects of some factors, including porosity, ionomer content, Pt/C particle size and Pt weight percentage in the Pt/C catalyst, on catalyst utilization were investigated and discussed.
