Chem Soc Rev: Asymmetrically Tailored Catalysts for Electrochemical Energy Conversion with Non-Precious Materials

Electrocatalytic technologies, such as water electrolysis and metal-air batteries, open new pathways for sustainable energy storage and conversion. However, traditional catalysts are limited by the trade-offs between activity, stability, and scalability. Asymmetrically tailored electrocatalysts (ATEs) have emerged, breaking these limitations through asymmetric design in composition, size, shape, and coordination environment. We focus on the latest … Read more

Co-Porphyrin-Based Covalent Organic Frameworks for O2 Reduction

Introduction Recently, Professor Luis Echegoyen and others from the University of Texas at El Paso reported two covalent organic frameworks (COFs) based on Co(II)-porphyrin/[2,1,3]-benzothiadiazole (BTD), namely Co@rhm-PorBTD and Co@sql-PorBTD, and used them for O2 electrocatalytic reduction (ORR). The results show that both COFs exhibit 5.8 times (Co@rhm-PorBTD) and 1.3 times (Co@sql-PorBTD) higher mass activity compared … Read more

Regulating Oxygen Vacancy Concentration Activates Inert 2D Bi₂O₃ Nanosheets for Efficient HER

The oxygen vacancy (Vo) is closely related to the activity of hydrogen evolution reaction (HER) in electrocatalysts. However, the role of vacancy defects and their concentration effects remain unclear. Here, we selected Bi₂O₃ as a model, which is an unfavorable electrocatalyst for HER due to its non-ideal Gibbs free energy of hydrogen adsorption (ΔGₕ), to … Read more
