Imagine turning something as harmful as carbon dioxide (CO

2

) into useful chemicals. That's what CO

2

 electroreduction is all about! This process isn't just good for the environment; it can also make some valuable products. Scientists have been working hard to make this process better by designing new catalysts, understanding how reactions work, and creating better equipment. But there's still a long way to go before this becomes a big thing in industry.

One of the main challenges is that it uses a lot of energy and costs a lot of money. Plus, there are only a few products that can be made from CO

2

 electroreduction right now. To make this process more practical, researchers are looking beyond just the catalysts. They're focusing on the reactions and systems involved. The goal is to make the reactions more efficient, cheaper, and able to produce a wider range of products.

Some interesting strategies include combining CO

2

 reduction with other reactions, like oxidation. There's also the idea of reducing CO

2

 along with other elements like carbon, nitrogen, oxygen, or sulfur. Cascade systems and systems that capture and reduce CO

2

 all at once are also being looked into. These strategies could open up new doors for CO

2

 electroreduction.

But it's not all smooth sailing. There are still challenges ahead. Researchers have their own views on what these challenges might be and how to tackle them. Their insights could pave the way for future research and development in this exciting field.
