As a new environmentally friendly fuel that does not produce harmful gases when burned, hydrogen fuel is considered to be one of the most ideal green renewable energy sources that can replace fossil fuels. However, using natural gas or coal to extract hydrogen fuel is often very expensive. According to foreign media reports, Cardiff University in the United Kingdom recently came up with a method for extracting hydrogen fuel from fescue, which has increased the possibility of green plants providing energy for life on Earth.
Cellulose is the main component of the cell wall of green plants, and scientists are trying to extract hydrogen fuel from cellulose. Cardiff University collaborated with researchers at Queen's University Belfast to try to discover how to convert cellulose into hydrogen under the influence of light and catalysts. This process is often called photocatalysis.
In the experiment, the team used three metal catalystsâ€”palladium, gold, and nickel. The team mixed the three catalysts with the fescue cellulose in a flask and placed the flask under a lamp. Every 30 minutes, the gas sample was checked for hydrogen production. The researchers then used the fescue in the garden.
Professor Michael Bowker of Cardiff University stated: "Our results show that under the influence of sunlight and cheap catalysts, this method can produce a large amount of hydrogen. In addition, we have demonstrated the effectiveness of the fescue experiment. According to us It is known for the first time that this biological material is used to extract hydrogen. This method is of great significance because it avoids separating and purifying cellulose from the sample, which is very complicated and relatively expensive."
The results of this study were published in the Journal of the Royal Society A.
