Journal of Natural Gas Chemistry has renamed as Journal of Energy Chemistry starting from 2013During the past two decades, especially in the last decade, under the influence of many factors such as political, economic and social and environmental aspects, the trend of the energy exploration, research and applications has been extensively extended on one side, and are taking place deeply changes in the dramatic ups and downs on the other side. It is again revealed and confirmed that competition and innovation are the driving force for the development of science and technology. In consideration of this situation, we decide after more than two years of preparation to officially rename the Journal of Natural Gas Chemistry as the Journal of Energy Chemistry from 2013.Aims and ScopeThe Journal of Energy Chemistry is a publication that mainly reports on creative researches and innovative applications of chemical conversions of fossil energy, electrochemical energy and hydrogen energy, as well as the conversions of biomass and solar energy related with chemical issues to promote academic exchanges in the field of energy chemistry and to accelerate the exploration,research and development of energy science and technologies.The Journal functions as a medium for reporting original research papers dealing with topics in the fields of energy chemistry. It is devoted to up-to-date progress in the following fields all over the world:• Optimized chemical utilization of both conventional and unconventional fossil energies• Research and utilization of hydrogen energy• Conversion and storage of electrochemical energy• Capturing, storage and chemical utilization of CO2• New materials and nanotechnologies related to energy utilization• Chemical conversion of biomasses• Chemical approaches related to photo-catalysis
