Title
Preparation of LaSrCuO4 nanowires by carbon nanotubes and their catalytic and chemiluminescence properties for CO oxidation
Abstract

LaSrCuO4 nanowires were synthesized using carbon nanotubes (CNTs) in the presence of citrate; LaSrCuO4 nanoparticles were also prepared by a conventional citrate route in order to compare with the nanowires. The samples were characterized by transmission electron microscopy (TEM), high-resolution electron microscopy (HRTEM), frontier-transformed electron diffraction (FT-ED), X-ray diffraction (XRD), N2 adsorption isotherm and CO-TPD (temperature-programmed desorption) methods. The catalytic and chemiluminescence (CL) properties for CO oxidation over LaSrCuO4 catalysts with different morphologies were investigated further. The results revealed that CNTs and citrate played the key roles in controlling the morphology, crystallization and phase compositions of LaSrCuO4 catalyst; a high thermal stability of LaSrCuO4 nanowires against calcination was observed, and a high activity for CO oxidation was maintained.

Graphical abstractSingle-phase LaSrCuO4 nanowires were prepared using carbon nanotubes in the presence of citrate. After being calcined at 750 °C for 48 h, LaSrCuO4 nanowires showed a higher thermal stability and a higher activity for CO oxidation than the nanoparticle counterpart.
