Fuel cell catalyst solution: Laser graphene replaces platinum at lower cost
Recently, researchers at Rice University's Tour Laboratory successfully developed a lower-cost fuel cell catalyst solution. The catalyst uses laser to combine graphene with various metal nanoparticles, and the metal laser oxide obtained after the combination is embedded in the graphene body. The catalyst can maintain high activity in electrochemical redox reactions, and its metal loading The rate is less than 1at% (atomic percent). In summary, this kind of laser graphene can be used as a fuel cell catalyst instead of expensive platinum.
In addition, researchers mentioned in a paper published in the journal "ACS Nano" that nanoparticles can form different forms such as metal oxides or metal sulfides by adding different additives, allowing the compound to be used in other hydrogen production reactions, etc. remain active during electrocatalytic reactions.
Last year, James Tour and colleagues co-invented laser graphene. The so-called laser graphene is a flexible membrane material composed of porous graphene whose surface is formed after exposure of polyimide. Initially, researchers used commercially available polyimide flakes to make laser graphene. They later immersed boron in liquid polyimide to create laser graphene, which improved its ability to store electrical charges, making it a very efficient supercapacitor.
In a recent experiment, the experimenters fused cobalt solutions containing three different concentrations with iron or molybdenum metal salts. Each mixture was condensed to form flakes, which were then irradiated with infrared lasers and then heated at 750 Heated with argon gas at high temperatures of degrees Celsius.
The MO-LIGs produced by the above process are evenly distributed in graphene together with 10-nanometer metal particles. Experiments have shown that these substances can catalyze the oxygen reduction reaction, which is also 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. Essentially, hydrogen production is the process of catalyzing water into hydrogen.
