Bamboo is a natural, abundant, and low-cost lignocellulose source. Considering the industrial applications of renewable, biodegradable, and mechanically resistant support for heterocatalysis reactions, bamboo-based lignocellulose biomass can reserve new insight into this research field.1,2 The chemical and thermal stability, different catalyst immobilization strategies, reusability, and recovery of the lignocellulose biomass as catalytic support will be presented. Lignocellulose support from bamboo powder of Dendrocalamus giganteus, has been used to immobilize different lipases (Candida Antartica and Rhizomucor miehei). 3 The biocatalytic transformations in batch mode were demonstrated for the esterification of fatty acid and hydrolysis of olive oil. For the first time, the kinetic resolution of a racemic solution of 1- phenylethanol was applied in a packed bed column flow bioreactor.3 More recently, carboxylated lignocellulose slices were used to anchor copper nanoparticles (Cu-NPs) onto the external surface, or copper ions (Cu+2/Cu+1) were deposited into the internal vascular bundles to catalyze azide-alkyne cycloaddition (CuAAC) reactions in batch mode4 and flow mode,5 respectively. The pioneering exploration of the bamboo vascular bundles as microfluidic channels allowed the prototyping of the first copper-functionalized lignocellulose microreactor (Cu-LμR) for CuAAC. The versatile use and the scalable production of bamboo-based biomass in different forms (powder, slice, or microarray channels) are the benchmarks of this innovative and sustainable catalytic support. Bamboo-based lignocellulosic biomass has been demonstrated as a useful chemical platform for several heterocatalytic reactions in aqueous ambient for more sustainable green chemistry solutions. Regarding the interest in the new circular economy, we believe that these new findings could pave the wave for the industrial production of lignocellulose-based biodevices.
