摘要： Disclosed is a method of preparing a catalyst having a conductive oxide protective layer. The method may include providing (e.g., supplying) a carbon support having a metal catalyst supported thereon to a fluidized bed reactor, and forming a conductive oxide protective layer using atomic layer deposition (ALD). Particularly, the atomic layer deposition may include supplying a conductive oxide precursor to the fluidized bed reactor, conducting a first purging by supplying an inert gas to the fluidized bed reactor, converting the conductive oxide precursor to conductive oxide by supplying a reactive gas to the fluidized bed reactor, and conducting a second purging by supplying an inert gas to the fluidized bed reactor.

摘要： Disclosed is a method for preparing a metal catalyst composite. The method includes pre-treating a carbon support in a reactor, and depositing a metal precursor on the pre-treated carbon support. The pre-treating the carbon support may include exposing the carbon support to a nucleating agent, for example, titanium tetrachloride (TiCl4), silicon tetrachloride (SiCl4) and carbon tetrachloride (CCl4).

摘要： A method for producing a catalyst for a fuel cell comprising: a) injecting carbon particles into a fluidized bed reactor; b) evacuating the fluidized bed reactor to form a base pressure; c) introducing a catalytic metal precursor together with a carrier gas into the fluidized bed reactor to contact the catalytic metal precursor with the carbon particles; d d) purging a purge gas into the fluidized bed reactor; e) introducing a reaction gas into the fluidized bed reactor to attach the catalytic metal precursor to the carbon particles; and f) purging a purge gas into the fluidized bed reactor, wherein, the catalytic metal is attached to the carbon particles in a form of nano-sized spot.
