“…synthesized an ordered mesoporous carbon with morphology of nanoellipsoid. [ 49 ] In addition, the use of different hydrothermal conditions, such as addition of Borax or hypersaline conditions, has been reported to yield the high specific surface area carbons. For example, HTC of glucose in the presence of LiCl and ZnCl 2 gave a surface area carbon of 673 m 2 g −1 .…”

It is desirable for a sustainable society that the production and utilization of renewable materials are net‐zero in terms of carbon emissions. Carbon materials with emerging applications in CO2 utilization, renewable energy storage and conversion, and biomedicine have attracted much attention both academically and industrially. However, the preparation process of some new carbon materials suffers from energy consumption and environmental pollution issues. Therefore, the development of low‐cost, scalable, industrially and economically attractive, sustainable carbon material preparation methods are required. In this regard, the use of biomass and its derivatives as a precursor of carbon materials is a major feature of sustainability. Recent advances in the synthetic strategy of sustainable carbon materials and their emerging applications are summarized in this short review. Emphasis is made on the discussion of the original intentions and various sustainable strategies for producing sustainable carbon materials. This review provides basic insights and significant guidelines for the further design of sustainable carbon materials and their emerging applications in catalysis and the biomedical field.

“…For instance, ordered mesoporous channels in solids improve mass transfer and diffusion as well as expose active sites. 5 Moreover, they enhance the accessibility of the entire surface area for adsorption of various ions and molecules. Mesoporous metal oxides have already shown a great performance in various catalytic processes because of their large pore sizes and high pore volume.…”

“…In addition, oligomers and monomers from biopolymers can be obtained by pyrolysis and hydrolysis and utilized as raw materials or as a supply of clean energy. [ 2 ] Biopolymers can be applied to directly construct functional materials, such as precursors for catalysis [ 3 ] and energy storage. [ 4 ] Biomimetic materials can also be designed based on inspiration from the function and ordered structures found in biopolymers.…”

Biopolymers, a class of fascinating polymers from biomass provide sustainability, biodegradability, availability, biocompatibility, and unique properties. A ubiquitous feature of biopolymers is their hierarchical structure, with the presence of well‐organized structures from the nanoscale to macroscopic dimensions. This structural organization endows biopolymers with toughness, defect resistance, and bucking adaptability. To retain these inherent structural features, nano‐structural assemblies isolated from biomass have been applied as building blocks to construct new biopolymer‐based materials. This top‐down processing strategy is distinct from the more traditional molecular‐level bottom‐up design and assembly approach for new materials. In this review, the hierarchical structures of several representative biopolymers (cellulose, chitin, silk, collagen) are introduced with a focus on these nanoscale building blocks, as well as highlighting the similarities and differences in the respective chemistries and structures. Recent progress in production strategies of these natural building blocks are summarized, covering methods and treatments used for isolations. Finally, approaches and emerging applications of biopolymer‐based materials using these natural nano‐ and meso‐scale building blocks are demonstrated in areas of biomedicine, electronics, environmental, packaging, sensing, foods, and cosmetics.
