Tunable Interfacial Electric Field‐Mediated Cobalt‐Doped FeSe/Fe3Se4 Heterostructure for High‐Efficiency Potassium Storage

Angewandte Chemie, Journal Year: 2024, Volume and Issue: 136(28)

Published: April 25, 2024

Abstract The interfacial electric field (IEF) in the heterostructure can accelerate electron transport and ion migration, thereby enhancing electrochemical performance of potassium‐ion batteries (PIBs). Nevertheless, quantification modulation IEF for high‐efficiency PIB anodes currently remains a blank slate. Herein, we achieve first time tuning via amorphous carbon‐coated undifferentiated cobalt‐doped FeSe/Fe 3 Se 4 (denoted UN‐CoFe 5 /C) efficient potassium storage. Co doping increase , improving transport, promoting adsorption capacity, lowering diffusion barrier. As expected, magnitude /C is experimentally quantified as 62.84 mV, which 3.65 times larger than that (Fe /C). Benefiting from strong IEF, anode exhibits superior rate capability (145.8 mAh g −1 at 10.0 A ) long cycle lifespan (capacity retention 95.1 % over 3000 cycles 1.0 ). Furthermore, this strategy universally regulate CoSe 2 /Co 9 8 FeS /Fe 7 S heterostructures. This work provide fundamental insights into design advanced electrodes.

Urchin-like TiO₂/CdS Nanoparticles Forming an S-scheme Heterojunction for Photocatalytic Hydrogen Production and CO₂ Reduction

ACS Applied Nano Materials, Journal Year: 2023, Volume and Issue: 6(23), P. 21897 - 21908

Published: Nov. 21, 2023

The use of semiconductor nanoparticle heterojunctions for photocatalytic activities is a very attractive strategy. TiO2/CdS widely used in the degradation pollutants, but there are few reports on hydrogen production and CO2 reduction. In this work, rod fishbone CdS nanoparticles were prepared by hydrothermal method, S-scheme with sea urchin morphology designed. With Na2S Na2SO3 as sacrifice agents, H2 yield was 1.07 mmol·h–1·g–1, [Ru(bpy)3]Cl2·6H2O photosensitizer TEOA agent, rate CO from reduction 47.67 μmol·h–1·g–1. preparation rates 9 times 13.3 TiO2 3.1 1.7 CdS/TiO2 composite particles, respectively. electron transfer path mechanism deduced EPR, TRPL, UPS, etc. results showed that construction heterojunction enhanced performance catalyst. We synthesized first time applied it to CO2. This work provides an effective reference designing high-performance inorganic catalysts.

CdBi₂S₄-Decorated Aminated Polyacrylonitrile Nanofiber for Photocatalytic Treatment of Cr(VI) and Tetracycline Wastewater

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(12), P. 5611 - 5622

Published: March 13, 2024

The significant threat posed by the high toxicity of heavy metals and antibiotics in water pollutants has prompted a growing emphasis on development highly efficient removal methods for these pollutants. In this paper, flexible electrospinning polyacrylonitrile (PAN) nanofiber-supported CdBi2S4 was synthesized via hydrothermal method, followed amination treatment with diethylenetriamine (DETA). as-prepared CdBi2S4/NH2–PAN nanofiber, enriched sulfur vacancies, demonstrated outstanding visible-light trapping ability suitable band gap, leading to separation transport photogenerated carriers, ultimately resulting exceptional photocatalytic capability. optimal 3-CdBi2S4/NH2–PAN nanofiber achieved impressive reduction rates 92.26% Cr(VI) 96.45% tetracycline hydrochloride (TCH) within 120 min, which were much higher than those CdS/NH2–PAN, Bi2S3/NH2–PAN, CdBi2S4/PAN nanofibers. After five cycles, rate consistently remained above 90%. Their ease recovery from application environment contributes their practicality. Additionally, compared conventional suspended particle catalyzers, composite exhibited remarkable flexibility self-supporting properties.
