Influence of reaction time on growth of GaN nanowires fabricated by CVD method

13-Apr-2011 | Feng Shi, Chengshan Xue, Journal of Materials Science: Materials in Electronics, 2011

GaN nanowires have been fabricated successfully on Si (111) substrates coated with NiCl2 thin films by chemical vapor deposition method using Ga2O3 as raw material. The growth of GaN nanowires was investigated as a function of reaction times so as to study the influence of different durations on ...

Effect of ammoniating temperature on microstructure of one-dimensional GaN nanorods with Tb intermediate layer

14-Feb-2011 | Feng Shi, Chengshan Xue, Journal of Materials Science: Materials in Electronics, 2011

GaN nanorods have been successfully synthesized on Si (111) substrates by magnetron sputtering through ammoniating Ga2O3/Tb thin films. The influence of ammonating temperatures on microstructure, morphology and light emitting properties of GaN nanorods was ananlyzed in detail using X-ray ...

IR study on the reduction of NO and NO2 by hydrazine monohydrate over Fe-BEA zeolite

07-Sep-2010 | Se Min Park, Gon Seo, Young San Yoo, Hyun-Sik Han, Korean Journal of Chemical Engineering, 2010

The adsorption of NO and NO2 and their subsequent reduction by hydrazine monohydrate (HDM) over Fe-BEA zeolite were investigated using an FT-IR spectrophotometer equipped with an in-situ cell. Although NO and NO2 molecules were adsorbed on Fe species in an unaltered state, some of them reacted ...

Synthesis, characterization, and heterogeneous catalysis of polymer‐supported poly(propyleneimine) dendrimer stabilized gold nanoparticle catalyst

15-Jun-2010 | Murugan, Eagambaram; Rangasamy, Rajmohan, Journal of Polymer Science Part A: Polymer Chemistry, 2010

We report here, the synthesis of two types of heterogeneous nanoparticle catalysts viz., polymer-supported poly(propyleneimine)-G2 dendrimer stabilized gold nanoparticle catalysts using crosslinked poly(4-vinylpyridine) matrix (PSP4VP) as support material. The grafting of dendrimer on the surface ...
