In Operando Spectroscopic Techniques for Electro- and Photo-catalysis

  • Submission closed.

About this Research Topic

Heterogeneous catalysis at the electrode/electrolyte interface is of paramount importance to a variety of chemical conversion processes such as electrocatalytic water oxidation and CO2 conversion, as well as energy conversion processes like photocatalysis, and those occurring in fuel cells, solar cells, and batteries. Gaining deeper insight into the making and breaking of chemical bonds in real-time at the solid/liquid interface is crucial for developing a more energy-efficient process in a broad range of systems.

This Research Topic focuses on recent advances in experimental and computational in operando and in situ spectroscopy/microscopy techniques developed for the characterization of electro- and photocatalysts, as well as catalytic processes, in order to achieve a better understanding of the nature of active sites, reaction intermediates, and mechanistic pathways. This will ultimately lead to the rational engineering of improved and novel catalysts for a variety of chemistries. This article collection encompasses a broad range of heterogeneous processes, including but not limited to:

• photo-and electro-chemical process for the production of fuels and electricity
• processes relevant to Li-ion and Li-sulfur batteries
• redox biochemistry

Emphasis will be placed on electron and photon probes capable of providing molecular-level information about systems (such as TEM and STS/AFM), as well as system-level probes such as X-ray absorption spectroscopy (EXAFS and XANES), X-ray photoelectron spectroscopy (XPS), linear and non-linear infrared vibrational spectroscopy (SFG, DRIFTS, RAIRS, etc.), and time-resolved optical spectroscopy. Original research, reviews, perspectives, and mini-reviews are most welcome.


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
