In this study, the catalytic properties of Ni$$_{3}$$Sn and Ni$$_{3}$$Sn$$_{2}$$ powders were investigated for producing hydrogen from decomposing methanol in the temperatures from 593 to 953 K. The catalytic activities of Ni$$_{3}$$Sn and Ni$$_{3}$$Sn$$_{2}$$ both increased with increasing temperature, but Ni$$_{3}$$Sn showed much higher catalytic activity than Ni$$_{3}$$Sn$$_{2}$$. The results of an isothermal test performed at 873 K revealed that the catalytic activity of Ni$$_{3}$$Sn significantly increased with methanol decomposition time, indicating that Ni$$_{3}$$Sn was spontaneously activated. Ni$$_{3}$$Sn and Ni$$_{3}$$Sn$$_{2}$$ both showed a high degree of selectivity and both suppressed side reactions such as methanation and water-gas shift reaction. Surface analysis revealed that fine Ni-Sn particles were formed together with carbon deposited onto the catalyst surface. These Ni-Sn particles were supposed to serve as active sites for methanol decomposition.
