LaCoO3/tourmaline was prepared as catalysts on the methane catalytic combustion. As additive tourmaline, its effect on crystal growth and catalytic activity of LaCoO3, were investigated via X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), H2-temperature programmed reduction (H2-TPR) and catalyst evaluation techniques. SEM and TEM indicated that the...
A novel catalytic material La0.9Sr0.1MnO3 and tourmaline compound catalytic material was synthesized in the base of traditional catalytic material La0.9Sr0.1MnO3 which exhibited excellent catalytic activity for methane combustion. Different contents of tourmaline were added to give a series of La0.9Sr0.1MnO3 and tourmaline catalytic material through a sol-gel method. Samples above were characterized...
