Towards Artificial Photosynthesis | Alexey Cherevan | TEDxTUWienSalon

In his talk, Alexey Cherevan focuses on the idea of artificial photosynthesis - a process that aims to mimic the functions of biological systems by creating human-made materials able to convert water and carbon dioxide into useful chemicals relying solely on the energy of light. He discusses the capabilities and complexity of natural photosynthesis and shows how material scientists can be inspired by nature to recreate the process.
Alexey Cherevan is a junior research group leader based at TU Wien’s Institute of Materials Chemistry. He studied chemistry at Moscow State University and received his Ph.D. in physical chemistry from the University of Münster, after which he joined the TU to pursue his habilitation. His scientific focus is on functional inorganic and hybrid nanomaterials for a variety of energy-related applications. In particular, he develops novel tools towards the combination of the heterogeneous and homogeneous fields of photocatalysis.

This speech gives great hopes to our humanity! Very interesting topic!!! Thanks a lot

[@ggill1530]

Wow that’s a salute 🫡 for the science of modern day Thanks to all scientists for helping mankind grow

[@peterwurmsdobler4470]

Very interesting and promising.
Perhaps a detail, when gas bubbles form above the photo-catalyst layer, would that not be both hydrogen and oxygen? If so, how would they be separated? If not, where does the oxygen go?

[@user-wr5yj3jp5b]

Alex you are the Best :)

[@bhuvana6446]

Wow,...science is beautiful and destructive

[@denuisss]

Very interesting!!

Reversal: when artificial photosynthesis pulls so much carbon from the atmosphere we have to pull from the ground to balance it out again 🤔 /s

[@ronzloof]

What happens to cyanobacteria after it dies? Is controlled shalow pools that will bloom cyanobacteria can help fight carbon levels? Can we sceem the water of the dead bacteria and make ethanol or other camicals? And what is the value of the harmful toxic camical it produces? Can we use it in indestry?

I really very very interested in this new field Even though I dn't like biology

Photosynthesis is NOT efficient in nature. It only has an efficiency of about 1-3%. Turning sunlight into hydrogen and oxygen is fairly simple. All you need are 2 electrodes and a solar panel. This chemical reaction is very easy and is often done as a demonstration in schools. Using electrolysis, water can be split with an efficiency of 70% and most solar panels are about 20% efficient, but some are as efficient as 39%. This would give us an efficiency of 14% - 27%. however, If this photocatalytic water splitting exceeds this efficiency, it will be impressive, however. the question of weather it will be easier to mimic photosynthesis on a macro or micro (or mix of both) scale is still a question. Not really any impressive information was shown, but you have to keep in mind this is still a rather new field.

If only "Political Science" wasn't 5000 years behind Material Science ...

[@DaveE99]

How so? Poltical psychology has a good idea With what happens. It’s the media and parties that try to make a profit off of it that screw everything up.

[@user-if1up4yg9j]

very interesting but nothing is clear🤔

[@h-k7804]

Not clear how he is going to achieve all that, just explains photosynthesis natural vs artificial

[@raoul355]

lets take all the co2 we put in the atmosphere!🙌 and turn it into plastic :S

[@thegamechanger7157]

Solve that now
The co2 is the problem.
