Light-battery interactions for enhanced energy storage and operando spectroscopy
… two different routes - photobatteries and a new operando method called diffuse reflectance spectroscopy (DRS). Photobatteries are a new class of devices that aim to combine the properties of energy harvesting and storage within the same device architecture. These devices have been reported to …

Reconstruction of Rhodium Clusters During CO Oxidation and Consequences on The Reaction Mechanism
… for a particular chemical reaction, in-situ/operando spectroscopy, such as diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) and X-ray absorption fine structure (XAFS) spectroscopy, is usually implemented as characterization tools. However, understanding the limitation of …
