Xi-Lin Wu graduated in 2009 from the Dalian University of Technology with a degree in Applied Chemistry. He is currently pursuing his PhD under the supervision of Prof. Xiangke Wang and Prof. An-Wu Xu at the University of Science and Technology of China. As a joint doctor, he is now working at the Max Planck Institute for Polymer Research, Mainz, Germany, with Dr Markus Mezger and Prof. Hans-J¨ urgen Butt. His research activities are devoted to the area of design and synthesis of self-assembled nanomaterials as well as to the study of ionic liquids at solid interfaces by using techniques of X-ray reectivity (XRR) and wide-angle X-ray scattering (WAXS).

Introduction
There has been an increasing worldwide demand for the development of alternative energy techniques with greater efficiency and sustainability due to the fast consumption of fossil
carbonaceous gels, carbon nanotube based carbonaceous gels, graphene based carbonaceous gels and biomass derived carbonaceous gels are introduced, and their applications for supercapacitors are systematically discussed. Perspectives for the development of neotype carbonaceous gel based electrode materials for supercapacitors are given.

Carbonaceous hydrogels and aerogels are a large class of gels which have received much attention due to their multifunctional properties. The three-dimensional networks and porous structure of the carbonaceous gels can provide efficient diffusion of electrolyte ions and electrons, leading to promising applications in supercapacitors. This feature article gives an overview of the recent advances in the use of novel carbonaceous gels for supercapacitors. In particular, the synthetic methods for polymer derived
An-Wu Xu studied Chemistry and got his B.Sc. degree in 1988 from the Hefei University of Technology, and completed his PhD in Analytical Chemistry in 1998 at the University of Science and Technology of China under the supervision of Prof. Mao-Sen Zhang. He worked in the School of Chemistry and Chemical Engineering at Sun Yat-Sen University from 2000 to 2004. As a visiting scholar, he worked with Prof. Yimmy C. Yu's group in the Department of Chemistry at the Chinese University of Hong Kong in 2003. From 2004 to 2006, he worked as an Alexander von Humboldt Research Fellow in the Max Planck Institute of Colloids and Interfaces, Potsdam, Germany, with Prof. Helmut C¨ olfen and Prof. Markus Antonietti. He has authored and co-authored 130 refereed journal publications, nine book chapters, and six patents. He is currently a professor at the Hefei National Laboratory for Physical Sciences at Microscale and the Department of Materials Science and Engineering, University of Science and Technology of China. His current research focuses on synthesis of new nanostructured materials and hierarchical functional carbon materials, energy conversion and solar cells, as well as photocatalysis.
