An amperometric alcohol sensor by using electroless nickel as working electrode was developed. The sensing results were affected by the electrolyte composition, deposition time, and temperature of the electroless nickel. The results revealed that the best operating conditions of the electroless nickel were 70 °C deposition temperature, 20 min deposition time, and 2.632 ratio of reducing agent to nickel ion in the solution. The results also indicated that the response time of the prepared alcohol sensor is in the range from 10 to 13 s and the best sensitivity is 8.7 μA/ppm×cm 2 .
