Despite their excellent catalytic properties, applications of noble metal nanoparticles have been hindered by their tendency to coagulate, as well as the difficulty in retrieving and reusing them. Now researchers in China have developed a titania sea-urchin-shaped structure with an iron oxide core that resolves both difficulties while maintaining excellent catalytic activity in the supported metal nanoparticles…..
