Abstract Due to the broadband response and low selectivity of external light, negative photoconductivity (NPC) effect holds great potential applications in photoelectric devices. Herein, different photoresponsive carbon nanodots (CDs) are prepared from diverse precursors NPC CDs utilized achieve optoelectronic logic gates optical imaging for first time. In detail, mcu ‐CDs which by microwave‐assisted polymerization citric acid urea possess large specific surface area abundant hydrophilic groups as sites adsorption H 2 O molecules thereby present a high conductivity dark. Meanwhile, affinity permits light‐induced desorption heat thus endow with under illumination. The easy absorption contribute extraordinary ‐CDs. With CDs, flexible system established, achieving “NOR” or “NAND” operations high‐quality images. These findings unveil unique properties have advance

Doping metals and constructing heterostructures are pivotal strategies to enhance the electrocatalytic activity of metal–organic frameworks (MOFs). Nevertheless, effectively designing MOF-based catalysts that incorporate both doping multiphase interfaces poses a significant challenge. In this study, one-step Co-doped Co3O4-modified Ni-MOF catalyst (named Ni NDC-Co/CP) with thickness approximately 5.0 nm was synthesized by solvothermal-assisted etching growth strategy. Studies indicate formation Co–O–Ni–O-Co bond in NDC-Co/CP found facilitate charge density redistribution more than Co–O–Ni bimetallic synergistic effect NiCo NDC/CP. The designating achieved superior oxygen evolution reaction (OER) (245 mV @ 10 mA cm–2) robust long stability (100 h 100 1.0 M KOH. Furthermore, NDC-Co/CP(+)||Pt/C/CP(−) displays pregnant overall water splitting performance, achieving current cm–2 at an ultralow voltage 1.52 V, which is significantly lower commercial electrolyzer using Pt/C IrO2 electrode materials. situ Raman spectroscopy elucidated transformation NDC-Co Ni(Co)OOH under electric field. This study introduces novel approach for rational design OER electrocatalysts.

Rational Construction of a 3D Self-Supported Electrode Based on ZIF-67 and Amorphous NiCoP for an Enhanced Oxygen Evolution Reaction

Inorganic Chemistry, Год журнала: 2024, Номер 63(30), С. 14062 - 14073

Опубликована: Июль 17, 2024

The development of efficient and Earth-abundant electrocatalysts for the oxygen evolution reaction (OER) is an urgent requirement in field electrochemical water splitting. electrocatalytic performance OER can be greatly enhanced by synergistic combination zeolite imidazolate frameworks (ZIFs) transition-metal phosphides, both which individually exhibit promising capabilities this regard. In study, a novel amorphous NiCoP deposited on ZIF-67 sheets supported Ni foam (labeled as NiCoP/ZIF-67/NF) material was successfully synthesized using simple, secure, time-efficient two-step strategy. experimental results demonstrate that NiCoP/ZIF-67/NF possesses large active surface area with abundant sites. Also, effect interaction between ZIF-67, well Co within NiCoP, effectively enhance its under alkaline conditions. Consequently, exhibits outstanding catalytic activity overpotential (η) 175 mV at current density 10 mA cm
