Abstract

Recently, organic electrosynthesis has attracted tremendous interest in the fields of electrocatalysis and biomass. Cinnamaldehyde is an abundant natural biomass that can be simply extracted from cinnamon. Its various hydrogenated derivatives have been widely used in perfumes, medicines, and edible flavors. Here, we developed an efficient electrocatalytic system for the hydrogenation of cinnamaldehyde and achieved a record total faradaic efficiency of 87.54%, demonstrating fantastic energy utilization efficiency. For the main product, cinnamic alcohol, a partial faradaic efficiency of 41.15% was achieved at a current density of 50 mA cm−2, superior to prior reports. The conversion rate was estimated as 96.21% for a 7-hour continuous reaction. Furthermore, a preliminary techno-economic analysis (TEA) was carried out and it demonstrated that our electrocatalytic hydrogenation system is potentially profitable for upgrading cinnamaldehyde to high value-added chemicals.

Green Chemistry 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, but not limited to, the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998). Green chemistry is 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 is at the frontiers of this continuously-evolving interdisciplinary science and publishes research that attempts 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. Submissions on all aspects of research relating to the endeavour are welcome. The journal publishes original and significant cutting-edge research that is likely to be of wide general appeal. To be published, work must present a significant advance in green chemistry. Papers must contain a comparison with existing methods and demonstrate advantages over those methods before publication can be considered. For more information please see this Editorial. Coverage includes the following, but is not limited to: Design (e.g. biomimicry, design for degradation/recycling/reduced toxicity…) Reagents & Feedstocks (e.g. renewables, CO2, solvents, auxiliary agents, waste utilization…) Synthesis (e.g. organic, inorganic, synthetic biology…) Catalysis (e.g. homogeneous, heterogeneous, enzyme, whole cell…) Process (e.g. process design, intensification, separations, recycling, efficiency…) Energy (e.g. renewable energy, fuels, photovoltaics, fuel cells, energy storage, energy carriers…) Applications (e.g. electronics, dyes, consumer products, coatings, pharmaceuticals, preservatives, building materials, chemicals for industry/agriculture/mining…) Impact (e.g. safety, metrics, LCA, sustainability, (eco)toxicology…) Green chemistry is, by definition, a continuously-evolving frontier. Therefore, the inclusion of a particular material or technology does not, of itself, guarantee that a paper is suitable for the journal. To be suitable, the novel advance should have the potential for reduced environmental impact relative to the state of the art. Green Chemistry does not normally deal with research associated with 'end-of-pipe' or remediation issues.
