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. on page 3481.

封面功能：具有二氧化硅支撑的超小ZnO纳米颗粒的生物质衍生的N掺杂碳材料：苯并咪唑绿色合成的稳健催化剂（Chem。Eur.J.14 / 2018）

壳聚糖是一种可持续的，可生物降解的，无毒且廉价的材料，通常是从几丁质中获得的海产品加工副产品。此封面特征描绘了海洋，包括围绕硅胶（粉红色）缠绕的脱乙酰壳多糖（蓝色）的组合。煅烧后，壳聚糖转化为掺入ZnO纳米颗粒（红色球）的氮掺杂碳材料（灰色管状结构）。显示了一个模型反应，该反应证明了杂化结构催化苯甲醛和邻苯二胺合成2-芳基苯并咪唑。更多信息可以在X. Lan，G. Bai等人的论文全文中找到。在3481页。
