Patent ID: 10156015

Abstract:
A method for autocatalytic plating of nanoparticles on a carbon nanomaterial, the method including: providing a nanomaterial in a solution including an oxidizing agent, the solution being maintained within a first temperature range and stirring the solution for a first predetermined time period; heating the solution to reach a second temperature range, higher than the first temperature range, and stirring the solution for a second predetermined time period, shorter than the first time period, while maintaining the solution within the second temperature range; filtering and rinsing the nanomaterial; dispersing the nanomaterial in an aqueous solution including a sensitizing agent; immersing the nanomaterial in a mixture including seed particles adhering to the nanomaterial; collecting the nanomaterial; plating the nanomaterial by immersing in a plating solution including an aqueous metal source and a first aqueous reducing agent such that a metallic layer is grown on the nanomaterial from the seed particles.
