Non-polluting fuels, such as hydrogen, are widely considered to be a promising way to decrease the environmental problems caused by the burning of fossil fuels. Finding materials that can help us to generate these “clean” fuels is a difficult and time-consuming process. Computer simulation technology is the most important tool in this area, because it helps scientists to understand existing materials and can also help them to design new types of materials. In this article, we explain how certain materials can help us to produce hydrogen, a clean fuel, from water, and we also describe how computer simulation technology can offer a route for the discovery of new efficient materials.

Main Components

Increasing fossil fuels consumption and global warming have driven the global revolution towards renewable energy sources. Lignocellulosic biomass is the main source of renewable carbon-based fuels. The abundant intermolecular linkages and high oxygen content between cellulose, hemicellulose, and lignin limit the use of traditional fuels. Therefore, it is a promising strategy to break the above linkages and remove oxygen by selective catalytic cracking of C–O bond to further transform the main components of biomass into small molecular products. This mini-review discusses the significance of selectivity control in C–O bond cleavage with well-tailored catalytic systems or strategies for furnishing biofuels and value-added chemicals of high efficiency from lignocellulosic biomass. The current challenges and future opportunities of converting lignocellulose biomass into high-value chemicals are also summarized and analyzed.

Today, SO2 pollution has become a glaring problem especially in India and China. Thus, desulfurization of fossil fuels has become an essential area of research. Advances in experimental sciences to explain the desulfurization mechanism will be beneficial to the rational designing of more effective HDS catalysts. Several reaction pathways involving desulfurization of thiophene have been compiled. Also, a repertoire of the desulfurization pathways encountered in the author's laboratory has been provided. The results will not only throw light on some unusual mechanisms of desulfurization process but also break the popular belief that desulfurization is limited to C-S bond cleavage only. The reactions may also serve as a basis for engineering optimal catalysts for future applications.

Global warming is increasing due to accumulation of greenhouse gases (GHGs) in the earth’s atmosphere. This is leading to devastating consequences causing floods and droughts in different areas of the globe. The exploitation and burning of fossil fuels on a tremendous scale is the main reason for rising global warming. The approach of sustainable development may help in controlling the rising temperatures. Hydrogen fuel is one such promising alternative clean fuel, that could change the scenario as per the vision of ‘Hydrogen Economy’. A combined approach of switching to cleaner and greener fuel with increased natural sinks for CO2 can provide a better solution to global warming.
