In Situ Wood Delignification toward Sustainable Applications

Accounts of Materials Research, Journal Year: 2021, Volume and Issue: 2(8), P. 606 - 620

Published: Aug. 1, 2021

ConspectusAs one of the most abundant and versatile natural materials on Earth, recently wood has attracted tremendous attention from scientists engineers due to its outstanding advantages, including hierarchically porous microstructure, high mechanical strength, environmental friendliness, renewability, biodegradability. Wood's structure chemical components (e.g., cellulose, hemicelluloses, lignin) enable mechanical, ionic, optical, thermal properties be tuned via physical, chemical, and/or modifications. Among these various approaches, delignification bulk is fascinating, in which majority lignin hemicelluloses removed while leaving cellulose intact, maintaining wood's physical integrity hierarchical structure. This delignified unique, composed hollow, aligned channels made up microfibrils, particularly attractive given origin a sustainable renewable resource. As result, increasing for applications that go far beyond traditional utilization, such as lightweight yet strong structural materials, energy storage conversion, remediation, flexible electronics, bioengineering.This Account reviews recent developments strategies toward achievement advanced technologies applications, with focus research our group. Similar pulping bleaching, involves series nucleophilic reactions based alkaline Na2SO3 or Na2S systems (i.e., pulping) electrophilic, radical, oxidation H2O2, ClO2, NaClO bleaching) deconstruct, fragment, promote hydrophilicity macromolecules, finally make easier removed. We discuss partially near-completely wood, process-structure–property relationships. The resulting tunable properties, demonstrate functions, wide range building construction, green energy, electronics. Finally, potential challenges appealing perspectives situ are discussed. In delignification, powerful modification strategy, speeded development wood-based functional products.

A Biodegradable, Waterproof, and Thermally Processable Cellulosic Bioplastic Enabled by Dynamic Covalent Modification

Advanced Materials, Journal Year: 2023, Volume and Issue: 35(25)

Published: May 1, 2023

The growing environmental concern over petrochemical-based plastics continuously promotes the exploration of green and sustainable substitute materials. Compared with petrochemical products, cellulose has overwhelming superiority in terms availability, cost, biodegradability; however, cellulose's dense hydrogen-bonding network highly ordered crystalline structure make it hard to be thermoformed. A strategy realize partial disassociation hydrogen bonds reassembly chains via constructing a dynamic covalent network, thereby endowing thermal processability as indicated by observation moderate glass transition temperature (Tg = 240 °C), is proposed. Moreover, cellulosic bioplastic delivers high tensile strength 67 MPa, well excellent moisture solvent resistance, good recyclability, biodegradability nature. With these advantageous features, developed represents promising alternative traditional plastics.

Nanoscale Metal Particle Modified Single‐Atom Catalyst: Synthesis, Characterization, and Application

Advanced Materials, Journal Year: 2023, Volume and Issue: 36(2)

Published: July 13, 2023

Single-atom catalysts (SACs) have attracted considerable attention in heterogeneous catalysis because of their well-defined active sites, maximum atomic utilization efficiency, and unique unsaturated coordinated structures. However, effectiveness is limited to reactions requiring sites containing multiple metal atoms. Furthermore, the loading amounts single-atom must be restricted prevent aggregation, which can adversely affect catalytic performance despite high activity individual The introduction nanoscale particles (NMPs) into SACs (NMP-SACs) has proven an efficient approach for improving performance. A comprehensive review urgently needed systematically introduce synthesis, characterization, application NMP-SACs mechanisms behind superior This first presents classifies different through NMPs enhance SACs. It then summarizes currently reported synthetic strategies state-of-the-art characterization techniques NMP-SACs. Moreover, electro/thermo/photocatalysis, reasons are discussed. Finally, challenges perspectives future design advanced addressed.
