With the recent wild fires in Australia, climate change has been on everyone’s mind. According to the US Energy Information Administration, climate change is in part due to the excessive greenhouse gas emissions, 76% of which come from the burning of fossil fuels.
The greenhouse effect is when heat is trapped near the earths surface by greenhouse gases. There are natural green house gases like carbon dioxide from humans which raise the average temperature of the earth from around 0 degrees to 50, yet since we have continuously been burning more and more carbon dioxide through things like burning fossil fuels, the temperature of the earth keeps rising. Luckily, a group of researchers found a way to try to reduce that number.
A group of researchers tried to imitate photosynthesis by taking energy from the sun to generate chemical fuels, and were successful. Photosynthesis is the process that plants use in order to create food, and ultimately energy from the sun. In order to complete this conversion, H2O must be broken down and the hydrogen atoms must attach to carbon. Then eight electrons and four protons must be added to one molecule of carbon. Even with all these steps, the newly developed copper-iron based catalyst is what makes this process actually work. The carbon and iron “hold onto by their carbon and oxygen atoms“, which allows for enough time for hydrogen to attach to the carbon.
The process would create a significant change in the amount of greenhouse gas emission if done on a large scale. For this to happen, a artificial photosynthesis panel would have to connect to a source of CO2. While this strategy would be financially costly, the reward for our earth would far surpass any monetary value.
