hierarchically porous Materials Synthesis strategies and structure design
Chemical Society Reviews, 2017Co-Authors: Xiaoyu Yang, Baolian Su, Lihua Chen, Yu Li, Joanna Rooke, Clément SanchezAbstract:Owing to their immense potential in energy conversion and storage, catalysis, photocatalysis, adsorption, separation and life science applications, significant interest has been devoted to the design and Synthesis of hierarchically porous Materials. The hierarchy of Materials on porosity, structural, morphological, and component levels is key for high performance in all kinds of applications. Synthesis and applications of hierarchically structured porous Materials have become a rapidly evolving field of current interest. A large series of Synthesis methods have been developed. This review addresses recent advances made in studies of this topic. After identifying the advantages and problems of natural hierarchically porous Materials, synthetic hierarchically porous Materials are presented. The Synthesis strategies used to prepare hierarchically porous Materials are first introduced and the features of Synthesis and the resulting structures are presented using a series of examples. These involve templating methods (surfactant templating, nanocasting, macroporous polymer templating, colloidal crystal templating and bioinspired process, i.e. biotemplating), conventional techniques (supercritical fluids, emulsion, freeze-drying, breath figures, selective leaching, phase separation, zeolitization process, and replication) and basic methods (sol–gel controlling and post-treatment), as well as self-formation phenomenon of porous hierarchy. A series of detailed examples are given to show methods for the Synthesis of hierarchically porous structures with various chemical compositions (dual porosities: micro–micropores, micro–mesopores, micro–macropores, meso–mesopores, meso–macropores, multiple porosities: micro–meso–macropores and meso–meso–macropores). We hope that this review will be helpful for those entering the field and also for those in the field who want quick access to helpful reference information about the Synthesis of new hierarchically porous Materials and methods to control their structure and morphology.

Hierarchically porous Materials: Synthesis strategies and emerging applications
Frontiers of Chemical Science and Engineering, 2016Co-Authors: Minghui Sun, Lihua Chen, Chen Chen, Baolian SuAbstract:Great interests have arisen over the last decade in the development of hierarchically porous Materials. The hierarchical structure enables Materials to have maximum structural functions owing to enhanced accessibility and mass transport properties, leading to improved performances in various applications. Hierarchical porous Materials are in high demand for applications in catalysis, adsorption, separation, energy and biochemistry. In the present review, recent advances in Synthesis routes to hierarchically porous Materials are reviewed together with their catalytic contributions.

thiol ene click reactions and recent applications in polymer and Materials Synthesis
Polymer Chemistry, 2010Co-Authors: Andrew B. LoweAbstract:This review highlights examples of recent applications of both the radical-mediated and base/nucleophile-initiated thiol-ene reactions in polymer and Materials Synthesis. Initial discussion focuses on mechanistic aspects of these reactions and also notes some of the structural considerations, with respect to reactants, that should be considered when practising such chemistries. The review is not intended to be exhaustive but rather to serve as an illustration of the impressive versatility and clear potential of these thiol-based “click” reactions and to highlight examples demonstrating its broad utility.

nanometer sized semiconductor clusters Materials Synthesis quantum size effects and photophysical properties
The Journal of Physical Chemistry, 1991Co-Authors: Ying Wang, Norman HerronAbstract:Recent advances in the Synthesis of semiconductor clusters open a doorway for the systematic study of size-dependent cluster properties in the condensed phase. This article focuses on the size effect on the optical and photophysical properties. The authors first introduce fundamental concepts and proceed to a discussion of recent progress toward the understanding of the quantum size effect and dielectric confinement effect. They then discuss the current status of Materials Synthesis and the prospect for making monodisperse clusters of well-defined surfaces.

Graphene-based Materials: Synthesis, characterization, properties, and applications
Small, 2011Co-Authors: Xiao Huang, Freddy Boey, Shixin Wu, Zongyou Yin, Qiyuan He, Qingyu Yan, Xiaoying Qi, Qichun Zhang, Hua ZhangAbstract:Graphene, a two-dimensional, single-layer sheet of sp(2) hybridized carbon atoms, has attracted tremendous attention and research interest, owing to its exceptional physical properties, such as high electronic conductivity, good thermal stability, and excellent mechanical strength. Other forms of graphene-related Materials, including graphene oxide, reduced graphene oxide, and exfoliated graphite, have been reliably produced in large scale. The promising properties together with the ease of processibility and functionalization make graphene-based Materials ideal candidates for incorporation into a variety of functional Materials. Importantly, graphene and its derivatives have been explored in a wide range of applications, such as electronic and photonic devices, clean energy, and sensors. In this review, after a general introduction to graphene and its derivatives, the Synthesis, characterization, properties, and applications of graphene-based Materials are discussed.

Ionic Liquid Based Approaches to Carbon Materials Synthesis
European Journal of Inorganic Chemistry, 2015Co-Authors: Zai-lai Xie, Dang Sheng SuAbstract:Ionic liquids (ILs) have attracted continuous interest because of their remarkable physicochemical properties, including high thermal and chemical stability, nonflammability, negligible vapor pressure, designable cation/anion pairs, electrical and ionic conductivity, low melting points, and affinity towards many compounds. These properties make ionic liquids valuable in the creation of new Materials and new processes throughout almost the entire field of Materials chemistry. An emerging field is the use of ionic liquids in carbon-based nanoMaterials. Initially, ionic liquids were used as self-templating carbon sources for the generation of unusual carbon Materials in which homogeneous heteroatom doping (e.g., N, B, S) can be accomplished fairly easily. Later, ionic liquids were recognized as suitable for use in the conversion of biomass into porous carbon Materials, acting as both reaction media and porosity-directing regulator. Such applications open the door towards the Synthesis and accurate tuning of carbon nanostructures, for example, pore structure, morphology, heteroatom doping, and surface functionality. In addition, the hybridization of ionic liquids and nanocarbons enables the development of composites by combining the properties of the ionic liquid (e.g., ionic conductivity or catalytic activity) and those of a host (e.g., chemical or mechanical stability). Currently, although the research of this topic is rapidly expanding, the rational design and Synthesis of carbon-based Materials, particularly their applications in energy storage and transformation, is still in its infancy. In this review, we focus on several aspects of ionic liquid derived carbons with the aim of shedding light on this new topic: 1) Ionic liquids as an advanced medium for carbon Synthesis, 2) ionogels derived from nanocarbon, 3) ionic liquids as fluid precursors for functional carbons, and 4) ionic liquid derived carbons for heterogeneous catalysis.
