Using the natural polymer cellulose as a template, researchers in Russia have been able to produce fibrous nanostructures of ceria (cerium oxide) that show strong activity in a range of light ...

These methods are often simple and scalable but may have limitations in terms of size control and uniformity. Metal oxide nanoparticles, such as titanium dioxide (TiO2), zinc oxide (ZnO), and cerium ...

The paper describes how the scientists observed the nanoparticles forming as single platinum atoms aggregated on the cerium oxide surface ... which converts carbon dioxide (CO 2) and hydrogen ...
