Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts

EcoEnergy, EarlyView.
Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...

Polyelectrolyte Layer as a Work Function Modifier for Transparent Electrodes Enabling Efficient Perovskite Solar Cells With Superior Low‐Light Performance

EcoEnergy, EarlyView.
Polyelectrolytes represent a low‐cost and effective platform for tailoring charge extraction interfaces in inverted perovskite solar cells (PSCs). In this work, we introduce a protonated polyethyleneimine (PEI) layer (pH = 2) between the ITO electrode and the PTAA hole transport layer to increase the apparent work function of ITO by 0.066 eV and reduce

Boosting CO2 Selective Electroreduction to CH4 With High Efficiency Over Oxygen‐Riched Cu‐CeO2 Catalyst by Constructing Heterointerface Built‐in Electric Field

EcoEnergy, EarlyView.
Defect‐rich Cu‐CeO2 heterojunction generates a strong built‐in electric field, accelerates directional electron transfer from CeO2 to Cu, and enables highly selective and efficient CO2 electroreduction to CH4. ABSTRACT Electrochemical CO2 reduction reaction (CO2RR) to CH4 offers a sustainable route for carbon neutrality, but it is hindered by sluggish ...
