Scientists at the University of Tsukuba developed a method to produce uniform, hollow vessel-shaped crystals through spontaneous crystal growth. The crystals have hexagonal symmetry and can be used as tiny containers for nanotechnology experiments.
A breakthrough in green technology has successfully produced both hydrogen gas and hydrogen peroxide simultaneously from sunlight and water using a hematite photocatalyst. This innovation could lead to a solar water-splitting utilization system with greater added value, enabling the widespread adoption of carbon-neutral energy sources.
Cerium oxide mesocrystals can be fabricated in a controlled way using radiation chemistry, enabling tuning for applications such as solar cells and fuel catalysts. The unique structure of these nanomaterials allows for customization of optical, magnetic, or electronic properties.
Researchers used advanced transmission electron microscopy (TEM) to observe mesocrystals form in real-time, revealing a new pathway of crystallization by particle attachment. This discovery could help design materials for energy storage and understand natural mineralization.
Scientists successfully produced a photoanode with extremely high conductivity by annealing hematite mesocrystals to a transparent electrode substrate. This enabled the separation of electrons and holes quickly, promoting the oxidation reaction and achieving the world's highest solar water-splitting performance.
Scientists have successfully created a highly efficient method to convert sunlight into hydrogen using hematite mesocrystal-based photoanodes. This breakthrough improves light-to-energy conversion efficiency and enables large-scale production of clean fuel hydrogen, making it a viable source of renewable energy.
Researchers at Kobe University have developed a new photocatalyst that increases hydrogen production tenfold. By deliberately creating a lack of uniformity in size and arrangement of crystals, the team was able to spatially separate electrons and holes, preventing recombination and increasing conversion efficiency.
