摘要： Methods for the rapid synthesis of catalyst are disclosed herein, as well as catalyst formed from such methods. One method of the rapid synthesis of catalyst comprises first forming a solution that comprises a solvent, a precious metal precursor, a catalyst substrate, a reducing agent and a stabilizer. The solution is homogenized. The precious metal precursor is reduced to nanoparticles of the precious metal and the nanoparticles are deposited onto the catalyst substrate to form catalyst particles. Reducing and depositing comprise increasing a temperature of the solution with microwave irradiation at a controlled rate to a predetermined temperature and holding the solution at the predetermined temperature with microwave irradiation until the reduction and depositing are detected to be complete.
