Gold catalysts supported on ceria doped by rare earth metals for water gas shift reaction: influence of the preparation method

Andreeva, D.; Ivanov, I.; Ilieva, L.; Abrashev, M. V.; Zanella, R.; Sobczak, J. W.; Lisowski, W.; Kantcheva, M.; Avdeev, G.; Petrov, K. (2009)

Gold catalysts based on ceria, doped by various RE metals (La, Sm, Gd, Yb, Y) were studied. The influence of the preparation methods on structure, properties and catalytic activity in the WGS reaction was investigated. The ...
Investigation on the formation of Cu-Fe nano crystalline super-saturated solid solution developed by mechanical alloying

Mojtahedi, M.; Goodarzi, M.; Aboutalebi, M.R.; Ghaffari, M.; Soleimanian V. (2013)

In this study, the formation of super saturated solid solution in the binary Cu-Fe system was investigated. Three powder blends with 30, 50 and 70 wt.% of Fe were milled for different times to 96 h. The variations of lattice ...
