Recently, researchers at Rice University's Tour Laboratory successfully developed a lower-cost fuel cell catalyst solution. The catalyst uses a laser to combine graphene with various types of metal nanoparticles, and the combined metal laser oxide is embedded into the graphene body. The catalyst can maintain high activity in electrochemical redox reactions and its metal loading. The rate is less than 1 at% (atomic percent). In summary, such laser graphene can be used as a fuel cell catalyst instead of expensive platinum. In addition, the researchers in the "ACS Nano" magazine publicly released the paper mentioned that nanoparticles can be formed by adding different additives metal oxides or metal sulfides and other different forms, so that the compound can be in other hydrogen reaction Electrocatalytic reactions remain active. Last year, James Tour and his colleagues co-invented laser graphene. The so-called laser graphene is a flexible film material composed of porous graphene formed on the surface exposed by polyimide. Initially, researchers made laser graphene using commercially available polyimide sheets. Later, they immersed boron in liquid polyimide to generate laser graphene, thereby increasing its ability to store charge, making it a very effective supercapacitor. In a recent experiment, the experimenter fused three different concentrations of cobalt solution with iron or molybdenum metal salt. After each mixture was condensed, it could be formed into thin slices, and then irradiated with an infrared laser, and then at 750. Argon gas is used for heating at a high temperature in degrees Celsius. The MO-LIGs produced by the above process are uniformly distributed in the graphene with 10 nanometer metal particles. Experiments show that these substances can catalyze the oxygen reduction reaction, which is the most basic chemical reaction in fuel cells. The hydrogen production process can be used as a catalyst for the redox reaction by adding some sulfur to the metal. In essence, hydrogen production is a process of catalyzing water into hydrogen.
