Photothermal‐Enhanced S‐Scheme Heterojunction of Hollow Core–Shell FeNi₂S₄@ZnIn₂S₄ toward Photocatalytic Hydrogen Evolution

Small, Journal Year: 2024, Volume and Issue: 20(30)

Published: Feb. 27, 2024

Abstract Herein, guided by the results of density functional theory prediction, study rationally designs a hollow core–shell FeNi 2 S 4 @ZnIn (FNS@ZIS) Step‐scheme (S‐scheme) heterojunction for photocatalytic H evolution with photothermal‐assisted. The FNS spheres offered substrate coating ZIS nanosheets, which can inhibit nanosheets from agglomerating into pellet, enrich active site, increase specific surfaces, and raise light absorption. Notably, due to its excellent photothermal properties, core generated heat unceasingly inside under visible‐light irradiation effectively prevent loss reaction system, increased local temperature photocatalysts thus accelerated charge migration. In addition, S‐scheme construction via in situ growth has tight interface, facilitate separation transfer carriers achieve high redox potential. Owning distinctive construction, FNS@ZIS show extraordinary stability rate 7.7 mmol h −1 g , is ≈15.2‐fold than pristine ZIS. Based on double evidence theoretical predictions experimental confirmations, effect electron mechanism this innovative material are investigated depth following infrared thermography technology deep DFT calculations.

Enabling CsPbBr₃ Perovskites for Photocatalytic CO₂ Methanation by Rationalizing a Z-Scheme Heterojunction with Zinc Phthalocyanine

ACS Materials Letters, Journal Year: 2024, Volume and Issue: 6(3), P. 999 - 1006

Published: Feb. 16, 2024

Perovskite materials are regarded as promising photocatalysts for light harvesting, yet they exhibit low photocatalytic activity due to serious charge recombination and lack of efficient catalytic sites toward CO2 reduction. Previous studies have employed perovskites reductive sides in a Z-scheme heterojunction suppress recombination, which however still encounter selectivity because the absence specific In this work, we report strategy that enables CsPbBr3 perovskite methanation. The central concept is construction using zinc phthalocyanine (ZnPc) side. enhanced separation CsPbBr3/ZnPc provides catalytically active ZnPc with sufficient energetic electrons As result, achieves up 89% 168 μmol g–1 h–1 CH4 production, well exceeding all reported perovskite-based photocatalysts. This work insights into rational design heterojunctions artificial photosynthesis.

Two-Dimensional High-Entropy Selenides for Boosting Visible-Light-Driven Photocatalytic Performance

ACS Nano, Journal Year: 2024, Volume and Issue: 18(31), P. 20740 - 20750

Published: July 23, 2024

High-entropy materials (HEMs) have garnered extensive attention owing to their diverse and captivating physicochemical properties. Yet, fine-tuning morphological properties of HEMs remains a formidable challenge, constraining potential applications. To address this, we present rapid, low-energy consumption diethylenetriamine (DETA)-assisted microwave hydrothermal method for synthesizing series two-dimensional high-entropy selenides (HESes). Subsequently, the obtained HESes are harnessed photocatalytic water splitting. Noteworthy is optimized HESes, Cd
