Summary: Studying the structure-activity correlations of electrocatalysts is crucial for improving the conversion of electrical to chemical energy. Recent evidence obtained through operando characterization techniques shows that the structural evolution of catalysts, caused by their interaction with electric fields, electrolytes, and reactants/intermediates, leads to the formation of real active sites. It is therefore important to summarize the research advances in structural evolution and envision future developments. In this Minireview, the fundamental concepts associated with structural evolution, the triggers of this evolution, and advanced operando characterizations are discussed. The reversibility of structural evolution in heterogeneous electrocatalysis, with a focus on the oxygen evolution and CO2 reduction reactions, is also highlighted. Finally, the key challenges and opportunities in this exciting field are presented.

Summary: Carbon dots (CDs) have been synthesized using ethanol as a carbon source, composed of blue-, cyan-, and yellow-emitting CDs which fluoresce at corresponding wavelengths. The red-shift in emission peaks is attributed to increased carbonization in polymer structure, leading to different surface states. Theoretically verified results have successfully been used in developing multi-color and white light-emitting diodes (LEDs).

Summary: We demonstrate the regulation of Lewis acid sites through coordinating zirconium nodes in metal-organic frameworks with monocarboxylate modulators. The use of electron-withdrawing TFA as the modulator leads to significantly enhanced catalytic performance in the ring-opening reaction of epoxides with alcohols, thanks to the stronger Lewis acidity and more active zirconium sites induced by TFA.
