Abstract

Synthesis and immobilization of caltrop cupric particles onto a Si substrate using
X-ray radiolysis directly from a liquid solution of Cu(COOCH3)2 is demonstrated.
Caltrop cupric oxide particles are formed in the X-ray radiolysis of
aqueous solutions of Cu(COOCH3)2, which also contain methanol, ethanol,
2-propanol or 1-propanol as OH scavenger. The blade lengths of the caltrop
particles are dependent on the alcohol chain length. In particular, it was found
that an alkyl alcohol whose chain length is longer than four is unable to
synthesize any particles in aqueous solutions of Cu(COOCH3)2 in X-ray
radiolysis. These results are attributed to the alkyl alcohol chain length
influencing the rate of reaction of radicals and determines the solvable ratio of
its alcohol into water. In addition, it was found that the synthesized particle
geometric structure and composition can also be controlled by the pH of the
aqueous solution in the X-ray radiolysis. This study may open a door to
understanding and investigating a novel photochemical reaction route induced
under X-ray irradiation. The development of the X-ray radiolysis process
enables us to achieve the rapid and easy process of synthesis and immobilization
of higher-order nano/microstructure consisting of various materials.
