Temperature-programmed-reduction studies of nickel oxide/alumina catalysts: effects of the preparation method
- Chiuping Li, Y. Chen
- Materials Science
- 1 June 1995
Abstract Two series of NiO Al 2 O 3 catalysts with various metal loadings were prepared by incipientwetness impregnation and coprecipitation methods. The reducibilities of NiO over these catalysts… Expand
Structural characteristics and redox behaviors of Ce1-xCuxOy solid solutions
- W. Shan, W. Shen, Chiuping Li
- Materials Science
- 28 October 2003
Nanosized Ce1-xCuxOy materials were prepared by complexation−combustion method. The structural characteristics and redox behaviors were investigated using X-ray diffraction (XRD), temperature… Expand
The mechanism of reduction of iron oxide by hydrogen
- H. Lin, Y. Chen, Chiuping Li
- Chemistry
- 17 April 2003
Abstract Precipitated iron oxide samples were characterized using temperature-programmed reduction. H 2 was used as the reduction agents. The two-stage reduction was observed: Fe 2 O 3 was reduced to… Expand
In situ growth of NiCo2S4@Ni3V2O8 on Ni foam as a binder-free electrode for asymmetric supercapacitors
- Leng-yuan Niu, Yidan Wang, +7 authors Y. Gong
- Materials Science
- 13 April 2016
A hierarchical NiCo2S4@Ni3V2O8 core/shell hybrid was in situ grown on nickel foam through a facile hydrothermal process combined with a simple co-precipitation method. Further characterization shows… Expand
Chemical signed graph theory
- S. Lee, Chiuping Li
- Mathematics
- 15 February 1994
Chemical signed graph theory is presented. Each topological orbital of an N-vertex molecular graph is represented by a vertex-signed graph (VSG) that is generated by assigning a sign, either plus or… Expand
Electronic properties of TiO2 doped with Sc, Y, La, Zr, Hf, V, Nb and Ta
- J. Pan, Chiuping Li, +5 authors B. Q. Chi
- Materials Science
- 16 May 2015
Abstract The segregation of dopant inevitably affects the thermodynamic stability and electronic properties of transition metal (TM) doped TiO 2 which were studied using first principles… Expand
