Preface to Special Issue on Electrochemical Energy Storage and Conversion

Energy utilization includes two aspects of storage and conversion. Both the density of energy storage and the efficiency of energy conversion are particularly considered in the application of energy. It is well known that chemical energy can be easily stored in chemical substances with high-energy density such as those containing hydrogen and lithium. Meanwhile, chemical energy can be highly converted into clean and efficient electrical energy through the systems of electrochemical energy storage and conversion, which include batteries, fuel cells, and electrochemical capacitors （also called supercapacitors）. Thus, the combination of chemical energy and electrochemical reactions makes full use of the advantages of chemical energy and electrical energy. Nowadays, systems of electrochemical energy storage and conversion have already played an important role in powering an increasingly diverse range of applications from electronic devices to cars.

Preface to the Special Issue on Energy Electrochemistry

Energy electrochemistry is one of the key branches of energy chemistry. Its main goal is to develop chemical energy storage devices with highperformance, high safety, long life and low cost for wide applications. The key research areas include lithium ion batteries, fuel cells and redox flowbatteries, and the key future directions include Li-S batteries, Li-air batteries, all solid-state batteries and batteries for wearable electronics. Recently therehave been some significant advances spanning from fundamental discovery to application-specific prototypes in this field. For this reason. J. Energy Chem.

Preface to Special Issue on New Energy Technology

There is an increasing concern about sustainable energy supply and problems relating to environmental issues such as global climate change. The development of new technologies is extremely important for creating energy materials, for improving efficiency of energy-related conversions, for developing novel catalysts and reactors, and so on. The present special issue of the Journal of Energy Chemistry contains 26 peer-reviewed manuscripts, with concerns on the newest progress in new energy technologies, including fuel cells （1）, Li-ion battery （l）, hydrogen production （1）, catalysts for energy applications （5）, CO2 capture （1）, CO2 utilization （3）, biofuels （2） and plasma applications （8）. We have also included four papers on theoretical studies that are playing more and more important roles in the design of materials and in mechanism studies. Especially, we have paid special attentions to novel technologies like supercritical water and plasma conversion. We have selected papers from the ＂2012 International Symposium on Plasmas for Catalysts and Energy Materials＂, held in Tianjin, China, from September 21 to 24, 2012.

Preface to Special Issue on Carbon Materials for Energy Application

The rising cost and limited availability of fossil fuels, and the increasing concerns related to their role on global pollution and greenhouse effect have pushed considerably the need to accelerate the transition to a more sustainable use of energy based largely on renewable energy sources. Nanocarbon materials play a critical role in this transition, as they are the key materials for components of different devices necessary in enabling this transition （batteries, fuel cells, solar cells, etc.）. This issue collects 22 contributions, including one perspective and six review papers on the topic of carbon materials for energy applications, written by well-known experts in this field. It is really an exciting special issue that gives a very updated view of this topic, as well as trends and outlooks in this breakthrough research area. The initial perspective paper introduces the different possibilities offered from the growing level of knowledge in this area, testified from the exponentially rising number of publications. It also discusses the basie concepts for a rational design of these nanomaterials. The lk）llowing six reviews address different specific aspects of synthesis, characterization and use of carbon nanomaterials, from fuel cells to composite electrodes, supercapacitors and photoelectrochemical devices for CO2 conversion. These reviews represent an unique opportunity for the readers to be updated on the latest developments of new carbon families such as fullerene, grapbene, and carbon nanotube, and their derived nanocarbon materials （from carbon quantum dots to nanohorn, nanofiber, nano ribbon, etc.）. Second generation nanocarbons, including modification of these nanocarbons by surface functionalization or doping with heteroatoms to create specific tailored properties, and nanoarchitectured supramolecular hybrids, are also discussed. Finally, 1 communication and 14 full articles discuss several aspects of the use of these nanocarbon materials to develop new catalysts for a range of applications （from biomass conversion to Fisher-Tropsch reaction and electrochemical devices） and new materials for energy storage and conversion （adsorption pumps, Li-ion and Li-S batteries, electrodes for electrochemical uses）. We thus believe that this special issue dedicated to the use and development of carbon materials for energy applications represents a unique occasion for young and experienced researchers as well as for managers in the field of sustainable energy to have an updated view on this enabling topic for the future of our society. We thus invite all to have this special issue as a privileged component of your bookshelf.

Recent advancements in metal-organic frameworks for green applications

A series of environmental and energy issues,such as global warming,water pollution,acid rain,and energy shortage,have to be settled urgently.Metal-organic frameworks(MOFs)are compounds consisting of metal ions or clusters coordinated to organic ligands,which show great promise for alleviating or mitigating these challenges owing to their outstanding physical and chemical properties.In this review,we summarize the recent advances of MOFs in the fields of green applications,including carbon capture,harmful gas removal,sewage treatment,and green energy storage.In addition,the challenges and prospects of the large-scale commercialized use of MOFs in handling environmental issues are also discussed.
