Article Synopsis
- Hydrogen spillover helps create defects and oxygen vacancies in TiO crystals, enhancing electron conductivity and visible light absorption.
- Crystal facet engineering improves photocatalytic activity by reducing recombination of photogenerated electrons and holes.
- Rutile TiO nanorods with varying aspect ratios were synthesized, with the Pt-deposited ones showing the best performance for visible light-driven H production due to the combined effects of Ti defects and effective charge separation.
Article Synopsis
- The first direct observation of a platinum cluster (Pt4) has shown that it can randomly change between different structures, known as isomers.
- Researchers used advanced microscopy techniques to achieve super high-resolution imaging, capturing the atomic positions of the cluster at nearly atomic scale and at very short time intervals (0.2 seconds).
- The data collected indicates that the process of isomerization for the Pt4 cluster follows a straightforward first-order kinetic model, meaning the rate of change is predictable and depends on the concentration of the cluster.
