Abstract

Magnetic Ni-Ru/50WX8 catalysts are synthesized with combined methods of conventional 10 chemical reduction method and electroless deposition. Catalysts can be easily recycled with 11 magnets owing to their intrinsic ferromagnetism. Thus, it is convenient to separate catalysts from 12 spent NaBH4 solution for further recycling. Effect of temperature on catalyst performance is less 13 significant at higher temperature, which is beneficial to devices without good regulations on 14 temperature. A rate of hydrogen evolution as high as 150 ml min-1 g-1 could be reached at 25°C, 15 which, equivalently, can generate 15 W of power through a PEMFC. Different variables that affect 16 the rate of hydrogen production are investigated. Activation energy of hydrogen generation using 17 such catalysts is estimated at about 52.73 kJ mol-1.
