- In Situ Monitoring the Role of Working Metal Catalyst Nanoparticles for Ultrahigh Purity Single-Walled Carbon Nanotubes
Tian-Chi Chen, Meng-Qiang Zhao, Qiang Zhang, Gui-Li Tian, Jia-Qi Huang and Fei Wei

Ultrahigh purity of single-walled carbon nanotubes (SWNCTs) with a carbon content of 99.5 wt% are formed by efficient growth of SWCNTs and partial oxidation of metal@C nanoparticles that is based on the in situ monitoring the role of working metal catalyst nanoparticles during chemical vapor deposition growth and CO2 purification of SWCNTs.

A highly active electrocatalyst of MoS2/MGF, where the MoS2 nanoparticles are formed uniformly on mesoporous graphene foams (MGF) via a facile solvothermal approach, is reported. The MoS2/MGF nanocomposites exhibit the high hydrogen evolution reaction activity with a low overpotential and large cathodic currents arising from MGF's high surface area, abundant mesopores, and highly conductive skeleton of graphene.

Morphological control over the bulk heterojunction (BHJ) microstructure of a small-molecule photovoltaic system is demonstrated using thermal treatment and solvent additives. Single crystal X-ray diffraction and transmission electron microscopy are utilized to investigate solid-state interactions and the BHJ morphology. Domain size and molecular order are crucial to achieving the 7.0% power conversion efficiency and over 90% internal quantum efficiency exhibited under optimized conditions.
- A Graphene Oxide and Copper-Centered Metal Organic Framework Composite as a Tri-Functional Catalyst for HER, OER, and ORR
Maryam Jahan, Zhaolin Liu and Kian Ping Loh
Article first published online: 21 MAY 2013 | DOI: 10.1002/adfm.201300510
A graphene oxide and copper-centered metal organic framework composite shows good performance as a tri-functional catalyst for the hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR).
- H-Doped Black Titania with Very High Solar Absorption and Excellent Photocatalysis Enhanced by Localized Surface Plasmon Resonance
Zhou Wang, Chongyin Yang, Tianquan Lin, Hao Yin, Ping Chen, Dongyun Wan, Fangfang Xu, Fuqiang Huang, Jianhua Lin, Xiaoming Xie and Mianheng Jiang

H-doped black titania with a crystalline core/amorphous shell structure (TiO2@TiO2-xHx) is synthesized by hydrogen plasma. Solar absorption is enhanced due to localized surface plasmon resonance. H doping reduces oxygen vacancies and eliminates the recombination of light-excited electrons and holes. These behaviors enable the black titania to be excellent for water splitting.
