Abstract Improving proton transfer is vital for electrocatalysis with porous materials. Although several strategies are reported to assist in channels, few studies dedicated improving at the local environments of active sites Herein, we report on new Co‐corrole‐based organic polymers (POPs) improved electrocatalytic oxygen reduction reaction (ORR) and evolution (OER). By tuning pore sizes installing relays Co corrole sites, designed synthesized POP‐2‐OH both channels sites. This POP shows remarkable activity ORR E 1/2 =0.91 V vs RHE OER η 10 =255 mV. Therefore, this work significant present a strategy improve site materials highlight key role such structural functionalization boosting electrocatalysis.

Regulating the cobalt phthalocyanine molecules by introducing adjacent cubic molybdenum carbide nanoparticles for accelerated proton transfer towards efficient CO2 reduction reaction

National Science Review, Год журнала: 2025, Номер unknown

Опубликована: Янв. 10, 2025

The electrochemical CO2 reduction reaction (CO2RR) is an important application that can considerably mitigate environmental and energy crises. However, the slow proton-coupled electron transfer process continues to limit overall catalytic performance. Fine-tuning microenvironment by accurately constructing local structure of catalysts provides a novel approach enhancing kinetics. Here, cubic-phase α-MoC1-x nanoparticles were incorporated into carbon matrix coupled with cobalt phthalocyanine molecules (α-MoC1-x-CoPc@C) for co-reduction H2O, achieving impressive Faradaic efficiency CO close 100%. Through combination in-situ spectroscopies, measurements, theoretical simulations, it demonstrated CoPc optimized configuration serve as active centers H2O activation reduction, respectively. interfacial water rearranged, forming dense hydrogen bond network on catalyst surface. This at electrode-electrolyte interface synergistically enhanced dissociation, accelerated proton transfer, improved performance CO2RR.
