Artificial photosynthesis learned from nature: New solar hydrogen production technology developed

Phys.org - Daegu Gyeongbuk Institute of Science and Technology | DECEMBER 2, 2024

Researchers have successfully developed a supramolecular fluorophore nanocomposite fabrication technology using nanomaterials and constructed a sustainable solar organic biohydrogen production system.

The research team used the good nanosurface adsorption properties of tannic acid-based metal-polyphenol polymers to control the self-assembly and optical properties of fluorescent dyes while also identifying the photoexcitation and electron transfer mechanisms. Based on these findings, he implemented a solar-based biohydrogen production system using bacteria with hydrogenase enzymes.

The findings are published in the journal Angewandte Chemie International Edition. The joint research was led by Professor Hyojung Cha at the Department of Hydrogen and Renewable Energy, Kyungpook National University and Professor Chiyoung Park at the Department of Energy Science and Engineering, Daegu Gyeongbuk Institute of Science & Technology.

During natural photosynthesis, chlorophyll absorbs light energy and transfers electrons to convert it into chemical energy. Artificial photosynthesis, which emulates this natural process of photosynthesis, uses sunlight to produce valuable resources, such as hydrogen, and it has garnered attention as a sustainable energy solution...more

1. Ok its a start

But I do have questions, but first they needed vitamin c as the feed stock, and created .1 gallon of hydrogen ( at normal pressure ) per hour.

What is the energy cost to make and purify absorbic acid to level needed. But I say its a good start hopefully they can do it in the long run as a net energy gain. Thats the problem with hydrogen, its nothing but a battery at this point, and one with large losses at every stage.
