MXene is a newly discovered 2D carbon-based material that predominantly conductive. The most common MXene, titanium carbide (Ti3C2), can be used as conductive to enhance the photocurrent generated by photoelectrochemical (PEC) sensors. In order produce sheets are of high quality for PEC sensors and other light-based applications, it imperative synthesis methods production continue improved an extensive understanding its properties gained. Several fluorinated non-fluorinated from MAX discussed in this review. Detailed description mechanical, optical, topological, electronic, electrochemical resultant MXenes also presented. A critical analysis density functional theory (DFT) data pure well changes optical bandgap when doped with heteroatoms form heterojunctions or ternary nanocomposites, extensively described. Additionally, systematic exposition done on current MXene-based sensors, highlighting parameters yield performing sensor. review concludes opinion future direction sensing field.

Single Atom Catalyst in Persulfate Oxidation Reaction: From Atom Species to Substance

Small, Год журнала: 2024, Номер 20(30)

Опубликована: Март 5, 2024

Abstract With maximum utilization of active metal sites, more and researchers have reported using single atom catalysts (SACs) to activate persulfate (PS) for organic pollutants removal. In SACs, atoms (Fe, Co, Cu, Mn, etc.) different substrates (porous carbon, biochar, graphene oxide, carbon nitride, MOF, MoS 2 , others) are the basic structural. Metal atoms, substances, connected chemical bonds all a great influence on electronic structures that directly affect activation process PS degradation efficiency pollutants. However, there few relevant reviews about interaction between substances during process. this review, SACs with species summarized investigate metal−support evaluate their effects oxidation reaction Furthermore, how reactive pathways also discussed. Finally, challenges prospects in PS‐AOPs proposed.

Fast Electrodeposition of MXene/PDA Composites for High‐Performance Bioelectronic Interfaces: An In Vitro Evaluation

Advanced Functional Materials, Год журнала: 2024, Номер 34(23)

Опубликована: Фев. 14, 2024

Abstract Bioelectrode is critical to many biomedical researches. However, traditional materials (typically noble metals) and manufacturing techniques limit the large‐scale production of bioelectrodes. Herein, a fast electrochemical approach proposed deposit versatile MXene/polydopamine (PDA) composites on metalized substrate. PDA coating can improve adhesion between MXene substrate, while provides rough surfaces with unique micro/nanostructure outstanding electrical/optical/thermal performance. The impedance as‐prepared bioelectrode at 1 kHz down 8.48 Ω cm 2 . corresponding cathodic charge storage capacity (CSC c ) injection (CIC) are up ≈250 6.59 mC −2 respectively, much superior that bare Pt other conventional material‐based electrodes. MXene/PDA also demonstrate robust stability under continuous electrostimulation for × 10 8 pulse cycles 1000 CV cycles. Moreover, show high rapid photothermal response. Photoelectrochemical activity observed photocurrent, ≈40 folds larger than Pt. utility this new electrode in ascorbic acid sensing demonstrated. Excellent biocompatibility verified via neuron test viability assay.

With a high porosity and highly adaptable topology, ZIF-67 is considered the most promising photocatalyst has received much attention development. However, photoactive electron extraction rate of still low, which major problem limiting its further In this paper, based on type I structure using quantum dots (QDs) as active site, we obtain QDs@ZIF-67/ZIF-8 heterostructure, ensures high-yield hydrogen efficiency. Quantum dots, transmission site photogenerated electrons, improve carrier utilization generated by strong absorption ability in visible-light region. Through careful characterization, it was found that optimal photocatalytic 4999.7 μmol·g–1·h–1, value 30 times higher than QDs, provides an innovative band gap-matching design for adjusting charge transfer characteristics QDs with narrow gap, realizes efficient visible light.
