Multilayered hollow transition metal nitride spheres made from single-source precursors for SERS analytics.

ABSTRACT: Traditional high-temperature and high-pressure synthesis routes make transition metal nitride (TMN) grains prone to sintering and agglomeration, thus synthesis of architectures with high specific surface area and pore volume is an urgent problem to be solved for the applications of TMNs. Here, a general single-source precursor route is designed to synthesize cubic-phase γ-Mo₂N multilayered hollow spheres with high specific surface area (191.3 m² g^-1) and pore volume (0.69 cm³ g^-1) under relatively mild conditions. Furthermore, by changing the metal composition of the precursor through ion exchange, a series of TMN (WN, TiN, VN, NbN, MoN/WN, MoN/WN/TiN) multilayer hollow spheres with high specific surface area (178.6-193.7 m²
