Abstract
Bioenergy is a key strategy for sustainability, yet the potential for biofuel production from chitin is under-exploited. Here, we report the cleavage of the inherently inert σ-type C–C bonds in chitin under the condition of initially breaking the unstable C–O bonds. Mechanistic studies indicate that by regulating the valence state of Ru and the interaction between RuOx and AC-HNO3-melamine, the ability of Ru nanoparticles to cleave C–C and C–O bonds can be controlled. One-pot sequential hydrogenolysis of chitin with RuOx/AC-HNO3-melamine resulted in a mixed alcohol yield 1.66 times that of commercial Ru/C. A mixed alcohol yield of 16.8% was achieved using raw chitin and green process conditions. We expanded the substrate range to include chitosan, N-acetyl-d-glucosamine, and glucosamine. This work demonstrates the potential of shell biorefinery to produce affordable clean energy.
期刊介绍：
Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
