A driving device and a driving method for an electric assisted bicycle are provided. The driving device includes a motor, a rotation speed sensor, a torque sensor and a controller. The rotation speed sensor senses a rotation speed value of a crank or a chainring of the electric assisted bicycle. The torque sensor obtains an average torque value applied by the crank to the chainring of the electric assisted bicycle. The controller controls an output of the motor in response to the rotation speed value and the average torque value.

A method for manufacturing metal nano particles having a hollow structure is provided. First, a suitable reducing agent is added into a first metal salt solution, and first metal ions are reduced to form first metal nano particles. Next, after the reducing agent is decomposed, a second metal salt solution with a higher reduction potential than that of the first metal is added. Then, the first metal particles are oxidized to form first metal ions when the second metal ions are reduced on the surface of the first metal by electrochemical oxidation reduction reaction, and thus, second metal nano particles having a hollow structure and a larger surface area are obtained. The method is simple and the metal nano particles with uniform particle size are obtained by this method.
