“…SnO2/graphene and Fe3O4/graphene heterostructures for Li-Ion batteries were also prepared via one pot microwave assisted reaction based on benzyl alcohol route [219,220]. The reaction of tin(IV) chloride and iron(III) acetylacetonate precursors in benzyl alcohol in the presence of graphene oxide (GO) resulted in tin and iron oxide nanoparticles bound to the graphene surface.…”

The Power of Non-Hydrolytic Sol-Gel Chemistry: A Review

et al. 2017

View full text Add to dashboard Cite

This review is devoted to non-hydrolytic sol-gel chemistry. During the last 25 years, non-hydrolytic sol-gel (NHSG) techniques were found to be attractive and versatile methods for the preparation of oxide materials. Compared to conventional hydrolytic approaches, the NHSG route allows reaction control at the atomic scale resulting in homogeneous and well defined products. Due to these features and the ability to design specific materials, the products of NHSG reactions have been used in many fields of application. The aim of this review is to present an overview of NHSG research in recent years with an emphasis on the syntheses of mixed oxides, silicates and phosphates. The first part of the review highlights well known condensation reactions with some deeper insights into their mechanism and also presents novel condensation reactions established in NHSG chemistry in recent years. In the second section we discuss porosity control and novel compositions of selected materials. In the last part, the applications of NHSG derived materials as heterogeneous catalysts and supports, luminescent materials and electrode materials in Li-ion batteries are described.

Graphene-based nanostructures exhibit good mechanical strength, high porosity, outstanding electrical conductivity, and excellent thermal and chemical stability, which in addition to its low cost, versatile functionalization chemistry, and relative ease of large-scale preparation make it ideally suited to serve as a key component for the development of new electrode materials. Recently, a wide variety of methods have been developed for the formation of porous graphene architectures to further improve the performances. Porous graphene provides abundant pathways for rapid ion diffusion and high accessible surface area. In this chapter, the recent continued breakthroughs in the preparation of porous graphene-based nanoarchitectures as well as their applications as electrode materials for electrochemical energy storage devices are introduced.

[ 7,8 ] These properties have made graphene be one of the most promising materials in the 21st century for supercapacitors, [ 9,10 ] Li-ion batteries, [ 11,12 ] and fuel cell. [ 13,14 ] Apart from graphene, other 2D nanomaterials have also been regarded as attractive materials recently, such as transition-metal dichalcogenides (TMDs), [15][16][17] layered double hydroxides, [18][19][20] transition metal oxide nanosheets, [21][22][23] and graphene analogues. [ 24 ] In addition, a variety of 2D composites with novel structures and exceptional properties were developed for high technology applications.MoS 2 with a sandwich interlayer structure is a typical TMD, which is formed by a stack of planes. Each plane is composed of covalently bonded three atom (S-Mo-S) layers, and adjacent planes are held together by weak van der Waals interactions. MoS 2 nanosheets with single layer or few layers exhibit unexpectedly exotic behaviors compared with the bulk MoS 2 . A few new strategies have been developed for the synthesis of MoS 2 nanosheets, such as modifi ed liquid exfoliation, [ 25 ] hydrothermal or solvothermal synthesis, [ 26,27 ] and laser thinning. [ 28 ] However, the MoS 2 nanosheets are easily agglomerated for high surface energy, which leads to serious decrease of the performance. One of effective solutions is dispersing the nanosheets on the support materials, [ 29 ] such as graphene, [30][31][32] carbon nanotubes, [ 33 ] and TiO 2 [ 34,35 ] . MoS 2 composites exhibit excellent performance in hydrogen evolution reaction, [ 36 ] lithium ion storage, [ 37 ] and catalysis, which could be attributed to the support of matrix materials. The effects of matrix materials for enhancing properties of MoS 2 composites are mainly preventing the agglomeration of MoS 2 , exposing active edge sites, providing electronic transmission channel and promoting the separation of photoelectrons from vacancies. However, the interfacial structure between MoS 2 and matrix materials requires further investigation.Montmorillonite (MMT) is one of the most abundant nature clay mineral with 2D sheet-like morphology. The montmorillonite sheets consist of three layer structural units (TOTs), which are composed of a central AlO 4 (OH) 2 octahedral sheet and two SiO 4 tetrahedral sheets. It is a promising matrix material for assembling nanoparticles for its 2D sheet-like morphology, large specifi c surface area, and abundant hydroxyl groups. Montmorillonite has also been successfully used to
