With fast increasing demand in liquid transportation fuels, limited and unevenly distributed petroleum resources, and volatile petroleum prices, coal liquefaction technologies have again received the world's attention since the beginning of this century. China has actively pursued R&D of coal liquefaction technologies in the past decade and is deploying the first and the largest direct coal liquefaction plant since WWII and the largest indirect coal liquefaction plants after Sasol, South Africa. This paper analyzes the historical developments of coal liquefaction technologies from science point of view, presents recent developments of the technologies in China, and identifies challenges of the technologies towards successful industrial application. © 2009 Elsevier Ltd.

How green was my valley: Green carbon science focuses on the transformations of carbon-containing compounds in the entire carbon cycle. The ultimate aim is to use carbon resources efficiently and minimize the net CO 2 emission. This holistic view also has ramifications for related fields including petroleum refining and the production of liquid fuels and chemicals from coal, methane, CO2, and biomass.

Two-dimensional titania nanosheets have been utilized to fabricate 2D titania-based mesoporous silica through a controlled sol-gel method, which can further serve as a robust and versatile template to construct various 2D heterostructures via a nanocasting technology. 2D titania-based CdS has been fabricated. This heterostructure manifests an excellent H2-production rate of 285 μmol·h-1 under visible-light irradiation and an apparent quantum yield of 6.9% at 420 nm. © 2013 WILEY-VCH Verlag GmbH & Co.

Carbon foams are reviewed by focusing on their preparation and application. Their preparation processes are discussed by classifying them into five categories: blowing and carbonization, template carbonization, compression of exfoliated graphite, assembly of graphene nanosheets and others. Through these processes, density of the foam, sizes of cells and windows, as well as physical properties, are successfully controlled. Carbon foams are expected to give certain contributions to modern technology as containers for active materials for thermal energy storage, electrodes of electrochemical devices and electric energy storage, adsorbents for large molecules, and others including microwave absorption. © 2015 Elsevier Ltd.

Nitrogen-containing porous carbon materials are ubiquitous with a wide range of technologically important applications, including separation science, heterogeneous catalyst supports, water purification, electrochemistry, as well as the developing areas of energy generation and storage applications. To date, a variety of approaches has been developed and applied to introduce nitrogen into the carbon matrix. It is important and necessary to design and control a hierarchical porous structure and the surface chemical groups of nitrogen-containing porous carbons for their applications. In this work, we summarize and compare recently reported routes for the preparation of nitrogen-containing porous carbon materials and the effect of nitrogen groups on its applications in adsorption, electrochemistry, catalysis/catalyst supports and hydrogen storage properties. © The Royal Society of Chemistry 2013.
