The Possibilities of Solar-Powered Water Splitting

The latest innovation in the solar power field is a procedure known as solar-powered water splitting. This revolutionary process is set to generate and store renewable energy through the use of artificial photosynthesis.


Such a feat is no easy achievement and researchers have, up until this point, only been able to attempt artificial photosynthesis using a series of processes that ultimately contradicted one another. Recently, researchers from Ludwig-Maximilians-Uiverstitat (LMU), Munchen were able to create the conditions that facilitate photosynthesis based on semiconductor nanoparticles and finally broaden the possibility that -powered water splitting might be used more practically and on a larger scale.

Photocatalytic Splitting

Solar-powered water splitting has been made possible by physicists Dr. Jacek Stolarczyk and Professor Jochen Feldmann, along with a team of chemists under the direction of Professor Frank Wurthner and many other dedicated scientists in solar power research. By building an all-in-one catalytic system, Stolarczyk and his colleagues were able to essentially recreate the processes typically only found during environmental photosynthesis. The photocatalysts serve as semiconductor nanoparticles that are able to absorb light. This light that is absorbed then generates negatively charged or electron particles. The positively charged particles enter in to the equation via a hole. Both the light absorption particles and the hole are separated from one another in such a way that allows water molecules to be transformed by the electrons into hydrogen and then oxidized via the hole in order to form oxygen. This process of water oxidation is the heart of artificial photosynthesis and helping put solar-power water splitting at the forefront of the solar field.

Stolarczyk mentioned to Science Daily this month that this process of photocatalytic splitting for the purposes of solar-powered water splitting has previously been attempted under a couple of other, yet ineffective methods. He and his team have been able to correctly position the holes, omit the use of any harsh chemicals, and ultimately streamline a process of artificial photosynthesis to make solar-powered water splitting a closer reality. The intricacies involved in making certain that the correct molecules line up with the proper conductors, among other potential problems, has proved challenging, but rewarding for Stolarczyk and his crew.

Nanorods to Facilitate Solar-Powered Water Splitting

Researchers at LMU found that in order for solar-powered water splitting to work effectively, both the positive and negatively charged particles must be kept separated. To do this and allow the particles to flow freely without interfering with the either one’s charge, nanorods made of a semiconducting material proved to be the most viable solution. These breakthroughs in the solar energy field could not have been possible without the cooperation of both physicists and chemists to pool together their resources and expertise.

Solar-Powered Water Splitting in the Future

In addition to efficiency, reduced costs are the name of the game when it comes to solar power. The procedures that are being perfected for solar-powered water splitting at LMU and elsewhere will certainly impact solar power as a whole. The more solar solutions scientists and solar power researchers can come up with, the better chance we have at evolving into a society that can get its energy needs met without destroying the environment.

Solar energy has revolutionized utility needs worldwide and inventive solutions such as solar-powered water splitting continue to perpetuate the fervor felt for this field and the possibilities solar power has to offer. We can surely take the research out of LMU as a sign that solar power is here to stay, as it is already starting to evolve. We are seeing intricate solar solutions be continually discovered at an accelerating pace. It should be clear that solar power is here to stay and the full integration of solar power into our daily lives is inevitable. This should be encouraging for all currently living generations, as well as the many generations to come. Saving our planet has been a source of heated debate in recent decades and to see solar power take the lead as one of our most trusted solutions is comforting and reassuring. We can look towards the future with renewed hope that our environment and planet as a whole may be spared thanks to solar power.
