About this Research Topic
With the depletion of fossil fuels and climate change, producing energy and chemicals in a sustainable and environmentally friendly way is extremely urgent at present. Catalysis plays a vital role in achieving this goal by designing new catalysts and discovering new chemical processes. Understanding the catalytic mechanism from a fundamental point of view is of paramount importance in this setting. However, there are three “gaps” in catalytic research between model and real catalysts, namely materials, pressures and complexity, to limit the insights into the working mechanism. Operando methodology provides a powerful tool to resolve this by directly correlating the dynamic structure of a catalyst with its performance under realistic conditions. The application of operando study covers many significant chemical reactions in heterogeneous and electrocatalysis, such as alkane oxidation, hydrogenation of carbon dioxide, hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, and ammonia synthesis.
This Research Topic aims to collect recent advances in operando study including spectroscopy and electron microscopy for heterogeneous catalysis and electrocatalysis in order to advance our understanding of the dynamic structure of catalysts under working conditions. This will benefit the ultimate goal of rational design of catalysts by combining ab-initio simulations and/or machine learning.
We invite the submission of Original Research, Review, Mini Review, Perspective articles on themes including, but not limited to:
• Development of operando spectroscopy and microscopy in improving spatial and temporal resolution
• Operando study in heterogeneous catalysis
• Operando study in electrocatalysis
• Development of new characterization techniques and cell design.
Keywords: Operando, catalysis, dynamic structure, spectroscopy, electron microscopy
