Green Electrochromic Film Formation via Phenylcarbazole Polymerization in Ionic Liquids

Chemistry – A European Journal, EarlyView.
The scheme depicts the three‐step electropolymerization of two electrochromic polycarbazole derivatives, 4‐(9H‐carbazol‐9‐yl)phenol and 4‐(3‐methoxy‐9H‐carbazol‐9‐yl)phenol, performed at constant potential using the green ionic liquid BMIM TFSI. This medium enables controlled polymer growth and enhances electrochromic performance, yielding robust and ...

Morphology Engineering Derived CoOOH With Tunable Oxygen Vacancies for Potential‐Dependent Selective Electrooxidation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Through a morphology engineering strategy applied to CoFe PBA precursors, we successfully fabricated the CoOOH active phase enriched with oxygen vacancies and abundant edge sites. The introduced oxygen vacancies not only enhance the strong adsorption capacity for oxygen‐containing substrates but also suppress the overoxidation of HMFCA, thus enabling ...
