 This research paper discusses the development of a new type of electrocatalyst for hydrogen production by water electrolysis. This electrocatalyst combines single-walled carbon nanotubes, SWCNTs, with platinum nanoparticles, 0.10Ps, allowing for a lower loading of 0.10Ps than traditional point-slash-sea catalysts. The resulting electrocatalyst has a low over-potential of 47 millivolts at a current density of 10 milliamps per centimeter squared when reacting with hydrogen, and can produce hydrogen at a faradaic efficiency of 97%. Additionally, the PM electrolyzer fabricated from this electrocatalyst has a high mass activity of 27,200 ampere per gram of point, which is 80 times higher than the performance of a point-slash-sea catalyst with a loading of 2.8 milligrams per centimeter squared.
