Abstract
This study describes a novel sustainable concept for the scalable direct fabrication and functionalization of nanocellulose from wood pulp with reduced energy consumption. A central concept is the use of metal‐free small organic molecules as mediators and catalysts for the production and subsequent versatile surface engineering of the cellulosic nanomaterials via organocatalysis and click chemistry. Here, “organoclick” chemistry enables the selective functionalization of nanocelluloses with different organic molecules as well as the binding of palladium ions or nanoparticles. The nanocellulosic material is also shown to function as a sustainable support for heterogeneous catalysis in modern organic synthesis (e.g., Suzuki cross‐coupling transformations in water). The reported strategy not only addresses obstacles and challenges for the future utilization of nanocellulose (e.g., low moisture resistance, the need for green chemistry, and energy‐intensive production) but also enables new applications for nanocellulosic materials in different areas.

Summary
Nanocelluloses could be used rication and functionalization of nanocellulose from wood pulp with reduced in functional coatings, barrier coatings, energy consumption. The organic acid-mediated hydrolysis of wood pulp is combined with modular surface engineering using organic catalysis and “click” chemistry (Figure 1).[30] The “organoclick” chemistry functionalization in our strategy should allow the selective surface modification of nanocellulose for different applications.
