Something exciting and new is on the horizon for the battle against climate change, and it couldn’t come at a better time! In a discovery that will likely open many doors to the future, scientists were able to create an artificial leaf that looks a lot like a real one and does the work of a real leaf too. (1)

Plants and trees aren’t just pretty; they are very necessary for the removal of carbon dioxide from our atmosphere. There are few other things on the planet that can perform this function, and advocates for the environment have been getting more vocal about issues like deforestation and its effects on the climate.

Of course, more plants and trees are necessary, and there are constant efforts toward that. In addition, we can make the photosynthesis process stronger and more effective in each plant. Simply maximizing the strength of its root system will accomplish that. But scientists knew that technology could lend a hand in this as well, so they got down to business with the experimentation.

How Does The Artificial Leaf Work? 

“We call it an artificial leaf because it mimics real leaves and the process of photosynthesis,” said Yimin Wu, the lead research engineer at the University of Waterloo. “A leaf produces glucose and oxygen. We produce methanol and oxygen.” (2)

The name of the environment-saving game is the eradication of carbon dioxide in the air. The artificial leaf accomplishes this by utilizing a substance called cuprous oxide. This is an easy-to-make substance that is the result of mixing glucose, copper acetate, sodium hydroxide, and sodium dodecyl sulfate. Together with water heated to a particular temperature, it becomes cuprous oxide. (2)

After the cuprous oxide is created, a new chemical process is begun. Utilizing that as a catalyst, combined with carbon dioxide and a beam of light, the result is a synthetic photosynthesis process that has been proven on a smaller scale. And there’s a bonus too! Not only does this mimic the natural process of photosynthesis, but it produces an effective substitute for fossil fuels as well. 

Onward And Upward!

Next steps for this fantastic scientific development will involve patenting the process and then scaling it up to commercial-grade use. Scientists will be able to use this chemical process to get right to the heart of some of Earth’s biggest carbon dioxide polluters, and hopefully, make a massive impact on the already massive issue of climate change. In addition to that, a much-needed assist with easing our dependence on fossil fuels will be most welcome.

Many people fear that time is running out for us to be able to turn the tide on our negative environmental impact. But scientists like Professor Wu know that we’re headed in the right direction. 

“I’m extremely excited about the potential of this discovery to change the game,” said Wu, a professor of mechanical and mechatronics engineering, and a member of the Waterloo Institute for Nanotechnology. “Climate change is an urgent problem and we can help reduce CO2 emissions while also creating an alternative fuel.” (1)
