N2  - Ionogels (IGs), also termed ion gels, are functional hybrid materials based on an ionic liquid (IL) and a polymeric, hybrid, or inorganic matrix. IGs combine the properties of the matrix such as mechanical strength with IL properties like high ionic conductivity, high thermal stability, or catalytic activity. IGs are thus attractive for many applications, but the vast majority of IGs made and published so far are bulk materials or dense films. Applications like sensing or catalysis, however, would benefit from IGs with high surface areas or defined surface morphologies or architectures. In spite of this, only relatively few examples of high-surface-area IGs have been made so far; this has mostly been achieved by electrospinning, which has proven to be a promising strategy towards advanced IGs. The current review discusses first developments and outlines the future potential of electrospun ionogels, predominantly from a materials and inorganic chemistry perspective.

N2  - Surface-enhanced Raman scattering (SERS) spectroscopy has emerged in recent years as a promising and powerful technique to investigate the reaction mechanism of heterogeneous catalysis. In this work, the reduction reaction of 4-nitrothiophenol (4-NTP) to its corresponding amino derivate catalyzed by gold took place between the gold nanoshell and gold nanostar. Due to the strong binding of thiol group to the gold surface, the molecular configuration of 4-NTP was fixed with NO2 group towards outside. The direct contact of NO2 group with catalytic gold nanostars ensured the reduction reaction went smoothly, which was monitored by SERS spectroscopy. The NO2 vibration Raman band showed a unique blue-shift without any appearance of dimerization product, indicating this catalytic reaction might follow a monomolecular mechanistic pathway.
