摘要：
The state of gold deposited from a chloride solution on the surface of the porous magnetite-carbon composite obtained from modified birch saw dust at 400 and 800°C was studied by electron microscopy, X-ray photoelectron spectroscopy, and XRD analysis. The shape and size of the deposited gold crystallites depend on the synthesis temperature of the composite. The deposited gold crystallites were mainly ray-shaped at the synthesis temperature of 400°C and spheroid at 800°C.
