Chitosan is a sustainable, biodegradable, non-toxic, and inexpensive material most often obtained from chitin as a by-product of seafood processing. This cover feature depicts the sea including the combination of chitosan (blue) entwined around silica gel (pink). Upon calcination, the chitosan transforms into nitrogen-doped carbon materials (grey tubular structures) incorporating ZnO nanoparticles (red balls). A model reaction demonstrating the synthesis of 2-arylbenzimidazoles from benzaldehyde and o-phenylenediamine catalyzed by the hybrid structure is shown. More information can be found in the Full Paper by X. Lan, G. Bai et al. (DOI: 10.1002/chem.201704823).
