A nano step for the development of cars that run on hydrogen
Nanotechnology and environment
Hydrogen by many countries of the Organization for Economic Cooperation and Development (OECD) It is considered as a major player in the movement towards carbon-free industries and sectors.
with help Nanomaterials With high performance, we can increase the efficiency of breaking the water molecule to produce hydrogen. This "clean" fuel, to reduce greenhouse gas emissions in the sector Transportation General can be effective. Hydrogen fuel is currently being used in several European countries and China. Buses equipped with this Technology, instead of Greenhouse gases They produce water!
For a long time, breaking water molecules into oxygen and hydrogen is done by electrolysis. However, many industrial electrolyzers energy consume and need investmentThey have big ones. INRS and ICPEES researchers were inspired by photosynthesis. They are electrodes Engineering They have produced a special substance that breaks water molecules under sunlight.
Nanotechnology and knowledge-based products
To make the most of solar energy, the research group chose TIO2, a semiconductor known for its sensitivity to UV light.. Ultraviolet rays make up only 5% of the sun's radiation. Using their expertise, this team has first changed the atomic composition of TIO2 and increased its light sensitivity to visible light.. They were able to produce electrodes that can absorb up to 50% of sunlight.
The researchers then manipulated the structure of the electrode scalers, formed a network of TIO2 nanotubes that has a honeycomb-like structure. This method increased the effective surface area of the electrode by a factor of 100,000 or more.
«Nano structure It maximizes the surface-to-volume ratio of the material. for example, NanoTIO2 structures can provide an area of up to 50 square meters per gram. It means that one gram of this substance has an area equal to a small apartment!»

The last stage of development of this electrode is their "nano decoration".. This process involves the deposition of catalyst nanoparticles on the TIO2 nanotube network to increase the efficiency of hydrogen production. For the nano-decoration, the researchers used laser ablation deposition, a field in which Al-Khakani has mastered for the past 25 years.. With this work, not only the challenge of controlling the size, dispersion and settling of catalyst nanoparticles on the TIO2 nanotube matrix was solved, but also other options were found for classical iridium and platinum catalysts..
In this research of cobalt oxide (CoO), a material readily available in Quebec, was used as an effective catalyst for the splitting of water molecules.. A comparison of the two substances showed that Nanoparticles CoO causes a tenfold increase in photocatalytic efficiency in these electrodes Nano New decorated under visible light compared to NanoThe pipes are exposed.
