Shape-Controlled CuCl Crystallite Catalysts for Aniline Coupling

Ting Xie, Ming Gong, Zhiqiang Niu, Shuai Li, Xiaoyu Yan, and Yadong Li ()
 
Department of Chemistry, Tsinghua University, Beijing 100084, China

DOI 10.1007/s12274-010-1020-6

Shape-controlled CuCl crystallites exposing different proportions of {111} and {110} crystal planes have distinctive catalytic properties for aniline coupling, which serves as evidence that {111} crystal planes have better catalytic activity than {110} planes.

In the aqueous-phase synthesis of Pd nanobars, nanocrystal growth at early stages of the reaction is dominated by particle coalescence, followed by shape focusing via recrystallization. The as-synthesized Pd nanobars contain several types of surface defects such as an adatom island, a vacancy pit, and steps.

    

Band Gap of Strained Graphene Nanoribbons

Yang Lu and Jing Guo () 
Department of Electrical and Computer Engineering, University of Florida, Gainesville, FL 32611, USA

DOI 10.1007/s12274-010-1022-4

The band gap of graphene nanoribbons can be engineered by strain, especially in the case of uniaxial strain applied to an armchair graphene nanoribbon. The band gap is roughly inversely proportional to the width of ribbon, and increasing the strain modulates the band gap in a periodic fashion.

    

Exchange-Biased NiFe2O4/NiO Nanocomposites Derived from NiFe-Layered Double Hydroxides as a Single Precursor

and Fazhi Zhang ()

State Key Laboratory of Chemical Resource Engineering, Beijing University of Chemical Technology, Beijing 100029, China

 

DOI 10.1007/s12274-010-1023-3

The topotactic transformation from NiFe-layered double hydroxide precursors to NiFe2O4/NiO nanocomposites through high-temperature treatment leads to an interfacial nanosystem with greatly enhanced magnetic stability. The blocking temperature of the final system is 380 K, about 100 K higher than a similar system prepared by calcination of a precursor prepared by a traditional coprecipitation method.
