The conversion of solar energy to produce clean hydrogen fuel through water splitting is an emerging strategy for efficiently storing solar energy in the form of solar fuel.This aligns with the increasing global demand for the development of an ideal energy alternative to fossil fuels that does not emit greenhouse gases.Electrochemical(EC) and photoelectrochemical(PEC) water splitting technologies have garnered significant attention worldwide for advanced hydrogen solar fuel production in recent decades.To achieve sustainable green H_(2) production,it is essential to create efficient catalyst materials that are low-cost and can replace expensive noble metal-based catalysts.These characteristics make them an ideal catalyst material for the process.Two-dimensional MXenes with M_(n+1)X_(n) structure have been identified as a promising option for EC and PEC water splitting due to their superior hydrophilicity,metal-like conductivity,large surface area,and adjustable surface chemistry.Here,we present a summary of recent advancements in the synthesis and performance enhancement methods for MXene hybrid materials in hydrogen production through EC and PEC water splitting.Furthermore,we examine the challenges and insights associated with the rational design of MXene-based hybrid materials to facilitate efficient water splitting for sustainable solar fuel production.

The unique luminescent performance of lanthanide complexes/clay minerals hybrid materials has been fascinating many researchers for recent decades.It not only retains the excellent luminescent characteristics of lanthanide complexes but also improves the poor stability of the complexes.In this article,we introduce the luminescence mechanism of lanthanide complexes and point out the necessity of their combination with clay minerals.After the analysis of the structure and interlayer environment differences of 1:1-type and 2:1-type clay minerals,the intercalation methods(covalent grafting and ion exchange)appropriate for different clay minerals are summarized with examples.Based on the luminescence characteristics of the hybrid materials,the applications of these materials as luminescent probes in recognition of specific metal cations and molecules,detection of pH value,and temperature are reviewed.Finally,the current problems in the preparation of lanthanide complexes/clay minerals hybrid luminescent materials and shortcomings that need improvement in their performance are analyzed,and the application prospect is forecast.

In this study,different carbon quantum dots(CQDs)/NaBiO3 hybrid materials were synthesized as photocatalysts to effectively utilize visible light for the photocatalytic degradation of contaminants effectively.These hybrid materials exhibit an enhanced photocatalytic reduction of hexavalent chromium(Cr(Ⅵ))in the aqueous medium.Zero-dimensional nanoparticles of CQDs were embedded within the two-dimensional NaBiO3 nanosheets by the hydrothermal process.Compared with that of the pure NaBiO3 nanosheets,the photocatalytic performance of the hybrid catalysts was significantly high and 6 wt.%CQDs/NaBiO3 catalyst exhibited better photocatalytic performance.We performed the first-principles density functional theory calculations to study the interfacial properties of pure NaBiO3 nanosheets and hybrid photocatalysts,and confirmed the CQDs played an important role in the CQDs/NaBiO3 composites.The experimental results indicated that the enhanced reduction of Cr(Ⅵ)was probably due to the high loading of CQDs(electron acceptor)on NaBiO3,which made NaBiO3 nanomaterials to respond in visible light and significantly improved their electron-hole separation efficiency.

Hierarchical porous cellulose/lanthanide hybrid materials as luminescent sensor

引用

Journal of Rare Earths 2018年第10期36卷 1036-1043页

作者： Wentao Fan Jiaojiao Du Junfeng Kou Zeyu Zhang Fengyi Liu College of Chemistry and Chemical Engineering Yunnan Normal University

Photoluminescent hybrid materials containing carboxymethyl cellulose and lanthanide ions（Eu3＋, Tb3＋）were prepared by a facile method under ambient conditions. Lanthanide ions were covalently grafted to the cellulose framework through coordination with the carboxylic groups of the cellulose. hybrid materials were fabricated as hydrogel and aerogel. As shown by SEM and pore parameters, aerogel materials which were obtained by supercritical CO2 drying show hierarchical porous structure. The photoluminescence spectrum of the hybrid materials shows the characteristic red emission of Eu3＋ ion and green emission of Tb3＋. Further luminescent investigations reveal that these hybrid materials can detect Fe3＋ with relative selectivity and high sensitivity, which suggests that the hybrid materials could be a promising luminescent probe for selectively sensing Fe3＋ ion.

Suppressing the dissolution of vanadium by organic-inorganic hybrid for aqueous zinc-ion batteries

Journal of materials Science & Technology 2023年第14期145卷 93-100页

Vanadium-based materials have been considered as the high promising cathodes for aqueous zinc ion batteries(ZIBs).Nevertheless,the dissolution of vanadium,the structural instability and the poor cy-cling stability largely hindered their applications.Metal organic frameworks(MOFs)and their deriva-tives attracted wide attention for their large specific surface area and structural tunability.Herein,MOFs derived·VO_(2)·Zn_(2)V_(2)O_(7)(MVHA)as organic-inorganic hybrids were constructed by the in-situ substitution method.The mixed valences of V 4+and V 5+between VO_(2)(B)and Zn_(2)V_(2)O_(7)were helpful to improve the electronic conductivity of MVHA cathode,and MOF-5-V acted as a physical barrier to inhibit the ca-thodic dissolution attributing to the particular organic frame structure.The obtained hybrid electrodes could deliver a high specific capacity(312.7 mA h g^(−1)at 1 A g^(−1)),and excellent long-term cycle stability(141.2 mA h g^(−1)after 1000 cycles at 10 A g^(−1)).Assistant density functional theory(DFT)calculations in-dicated that it has an ultra-low diffusion barrier of 0.32 eV for optimal Zn 2+diffusion path in MOF-5-V.The intriguing idea of in-situ compositing vanadium oxide and MOFs derived material opens up a new research direction for high-energy secondary batteries.

Organic electrosynthesis as an emerging green and advantageous alternative to traditional synthetic methods has achieved remarkable progress in recent years because sustainable electricity can be employed as traceless redox agents. To surmount the over-oxidation/reduction issues of direct electrolysis,mediated or indirect electrochemical processes are attaining remarkable significance and promoting the selectivity of products. Molecular electrocatalysts, benefiting from the easily electronic and steric modulation, suffers from readily degradation issue in most cases. Remarkably, heterogeneous catalysts have drawn more attention due to their high activity, stability, and recyclability. Hence, in this review, the most recent growth of heterogeneous catalysts modified electrodes for organic electrosynthesis were summarized, highlighting structural optimization and electrochemical performance of these materials as well as reaction mechanism. Furthermore, key challenges and future directions in this area were also discussed.
