Ag‐Regulated Cu‐Sites on a Conductive Cu‐Metal‐Organic Framework for Enhanced CO2 Electroreduction to CH4

open access: yesEcoEnergy, EarlyView.
We present a strategy of integrating Ag NPs with a 2D Cu3(HHTP)2 framework to boost selective CO2 electroreduction. The optimal composite achieves 65.1% FECH4 ${\text{FE}}_{{\text{CH}}_{4}}$ at 240 mA cm−2. Synergistic effects enhance CO2 adsorption, facilitate electron transfer, and selectively stabilize key reaction intermediates, steering the ...

Oxygen‐Vacancy‐Engineered Ru–V Dual Sites in InVO4 for Synergistic Photocatalytic N2 Activation and Reactive Hydrogen Supply

open access: yesEcoEnergy, EarlyView.
This study developed a catalyst composed of Ru nanoparticles directionally anchored at the oxygen vacancies of indium vanadate. Oxygen vacancy not only forms unsaturated V sites but also serves as an anchoring site for Ru nanoparticles, establishing a stable Ru‐V coordination structure through electronic metal–support interactions.

Ni–Pd Catalytic Synergy on Rod‐Shaped CeO2 for Boosting Low‐Temperature CH4 Oxidation

open access: yesEcoEnergy, EarlyView.
Introducing Ni into Pd/CeO2 markedly accelerates deep CH4 oxidation by inducing a synergistic interaction between Ni and Pd species. This synergistic effect significantly improves low‐temperature activity and long‐term stability, providing a rational strategy for efficient CH4 abatement over Pd‐based catalysts under lean CH4 conditions while reducing ...

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

open access: yesEcoEnergy, 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

Ni–Zn–Ga Alloy for Weak Sunlight‐Driven Methanol Production From CO2 and H2O at Ambient Pressure

open access: yesEcoEnergy, EarlyView.
The Ni–Zn–Ga ternary alloy‐assisted photothermal CO2 hydrogenation system coupled with photovoltaic water splitting could convert CO2 and H2O into methanol with a production rate of 709 μmol g−1 h−1 under natural sunlight irradiation. ABSTRACT The sunlight‐driven artificial photosynthesis that converts CO2 and H2O into methanol is a promising approach ...
