Monolayered Platinum Nanoparticles as Efficient Electrocatalysts for the Mass Production of Electrolyzed Hydrogen Water
Hydrogen, once it is activated, i.e., the H* species obtained via the hydrogen/platinum catalytic interaction, is a particularly important species. H* can penetrate into any part of our body and is capable of selectively reacting with reactive oxygen species (ROS).

Water symbolizes life; hydrogen, in Greek, means the "former of water". A research on combining water with hydrogen at nanoscales of combination for making healthy drinking water is undertaken by a jointed research team, which is leading by the University of Tokyo and Nihon Trim Co., Ltd of Japan. The use of nano-sized platinum (Pt) particles as the functioning linkers is the key to achieve this goal. A titanium plate with both sides being top-coated with mono-layered Pt nanoparticles is used as both cathode and anode. The average diameter of the Pt nanoparticles is approximately 100 nm. During the process of electrolysis of tap water, water molecules, hydronium ions, and hydroxyl ions, i.e., the three essential species of water adsorb properly on the Pt (111) facet of the Pt nanoparticles. Hydronium ions receive electrons and decay into hydrogen (H*) and water. H* is highly reactive and showing a tendency to penetrate into Pt nanoparticles; the rest parts of H* form hydrogen molecules. The reactive H* which has penetrated into Pt nanoparticles can be stored for a longer period of time. A certain amount of the Pt nanoparticles in which H* species are stored have escaped from the electrode and being then distributed in the electrolyzed hydrogen water (EHW). Quantitative analysis of Pt nanoparticles in EHW via ICP-MS confirms that the EHW contains 3 – 5 ppb Pt. EHW retains parts of biological activities: it is capable of improving gastrointestinal functionalities; also, it is capable of scavenging reactive oxygen species (ROS) in cells. As drinking water, pH of EHW is restricted at pH 9.2-9.8; nevertheless, the distinguishing healthier beneficial effects of EHW can be attributed to the highly reductive properties of H* in the EHW. H* can penetrate into any parts of our body and is capable of reacting with ROS. An illustration showing the potential health benefits of H* contained EHW is proposed: a dreamful mermaid is being fully recharged and is, right now, going to explore the fascinating new world by drinking the Pt-H*-contained EHW. Quantitative analysis of H* involved in Pt nanoparticles is remaining challenges. Nihon Trim Co. Ltd. is willing to donate the monolayered Pt-coated Pt/Ti electrodes but the donation is surely subject to the academic studies on EHW.
