Lamellar water sodium manganese
Researchers at Florida State University in the United States published a paper in a recent issue of the journal Physical Chemistry, stating that they have developed artificial materials that mimic photosynthesis and are expected to provide a sustainable self-sufficient energy system.
A sustainable, self-sufficient energy system should have no negative impact on the environment and would not produce carbon dioxide and wastewater. But to build such a system, the current challenge is how to design a material that will not rust in the process of decomposing water, but it will also capture energy and be cheap enough to facilitate production.
Jose Mendoza Cortes, associate professor of chemical engineering at Florida State University, initially developed a multilayered material called manganese birnessite with manganese oxide. Later, he and the research team peeled off this multi-layered material layer by layer. When there was only one layer left, exciting things happened and the speed of light capture increased. Technically, it has changed from an indirect bandgap material to a direct bandgap material.
Light energy penetrates the indirect band gap more easily without being absorbed. Silicon is the most common indirect gap material, but to make the material more efficient, silicon solar cells are usually stacked up to several hundred microns thick. If it is too thin, light will pass through the material. It is even more desirable to create a single-layer material that effectively traps light, which is simpler, cheaper, and easier to manufacture.
"So the discovery of direct bandgap materials was so exciting. It was cheap, efficient, and it didn't have to capture a lot of light to generate electricity as a fuel." Mendoza-Cottes said, "In theory, this is a kind of self-sufficiency. A self-contained energy system. Perhaps in the future, people can use this material on their own roofs to turn rainwater into energy in the sun."
Capture sunlight, and then use these light energy to break down water into hydrogen and oxygen. This process is called oxidation. When plants use light energy to break down water and carbohydrates, this reaction occurs and is the main source of energy for plants. According to the November 2 report of the Physicist Organization Network, the new discovery brings bright prospects for the use of this process for the production of new energy and zero carbon emissions.
