Ideal dimers comprising gold nanoparticles with a smooth surface and high sphericity are synthesized by a substrate‐based assembly strategy with efficient cetyltrimethylammonium bromide removal. An unprecedented structural and plasmonic uniformity at the single‐particle level is observed since inhomogeneities resulting from variations in gap morphology are eliminated. Single ideal dimers are analyzed...
In article number 1702754, Sebastian Schlücker and co‐workers synthesize ideal gold dimers of two spherical gold nanoparticles with a controlled gap distance and gap morphology. While theoreticians have been able to describe the properties of such a model system, experimentalists have failed to synthesize it. Here, elastic scattering of an ideal gold dimer using white light together with an electron...
Controllable and efficient synthesis of noble metal/transition‐metal oxide (TMO) composites with tailored nanostructures and precise components is essential for their application. Herein, a general mercaptosilane‐assisted one‐pot coassembly approach is developed to synthesize ordered mesoporous TMOs with agglomerated‐free noble metal nanoparticles, including Au/WO3, Au/TiO2, Au/NbOx, and Pt/WO3. 3‐mercaptopropyl...
Semiconducting metal oxides‐based gas sensors with the capability to detect trace gases at low operating temperatures are highly desired in applications such as wearable devices, trace pollutant detection, and exhaled breath analysis, but it still remains a great challenge to realize this goal. Herein, a multi‐component co‐assembly method in combination with pore engineering strategy is proposed....
