“…While previous studies have shown the cooperative coassembly or interfacial assembly of precursor- surfactant micelles toward anisotropic growth by a careful choice of surfactants, precursors, or/and additives, − this work is conceptually different from earlier approaches by directly using anisotropic-shaped soft templates (Figure ). Typically, the micellar structure is sensitive to environmental disturbance, and Wang et al have reported carbonaceous nanoflasks by making using of the thermal instability of the soft templates during synthesis .…”

“…For example, ethanol was skillfully selected as organic solvent to remove incomplete oligomers from polymer spheres and prepared bowl-shaped carbon nanoparticles after carbonization (Fig. 3 b) [ 33 ]. Specifically, the hollow polymer nanospheres were first prepared by the hydrothermal carbonization of glucose monomers using poly(ethylene glycol) (P123) and sodium dodecyl sulfate (SDS) as soft templates.…”

Highlights The synthetic strategies and fundamental mechanisms of various asymmetric carbon- and silica-based nanomaterials were systematically summarized. The advantages of asymmetric structure on their related applications were clarified by some representative applications of asymmetric carbon- and silica-based nanomaterials. The future development prospects and challenges of asymmetric carbon- and silica-based nanomaterials were proposed. Abstract Carbon- and silica-based nanomaterials possess a set of merits including large surface area, good structural stability, diversified morphology, adjustable structure, and biocompatibility. These outstanding features make them widely applied in different fields. However, limited by the surface free energy effect, the current studies mainly focus on the symmetric structures, such as nanospheres, nanoflowers, nanowires, nanosheets, and core–shell structured composites. By comparison, the asymmetric structure with ingenious adjustability not only exhibits a larger effective surface area accompanied with more active sites, but also enables each component to work independently or corporately to harness their own merits, thus showing the unusual performances in some specific applications. The current review mainly focuses on the recent progress of design principles and synthesis methods of asymmetric carbon- and silica-based nanomaterials, and their applications in energy storage, catalysis, and biomedicine. Particularly, we provide some deep insights into their unique advantages in related fields from the perspective of materials’ structure–performance relationship. Furthermore, the challenges and development prospects on the synthesis and applications of asymmetric carbon- and silica-based nanomaterials are also presented and highlighted.

“…As a facile, green, and effective approach, hydrothermal carbonization was introduced for the production of various functional carbon materials. ,− In the present work, with the biomass material xylose as the carbon precursor, it is the first time that the biomass-derived lignosulfonate was innovatively introduced together with PEO-PPO-PEO triblock copolymer P123 as soft templates during the hydrothermal carbonization processing. To the best of our knowledge, no research regarding introduction of the above two surfactants as the soft templates has been reported.…”

The carbon materials with diverse morphologies and structures have attracted much interest for various applications. In this work, by introducing lignosulfonate with PEO-PPO-PEO triblock copolymer P123 as soft templates, unique yolk–shell structure with pollen-like surface of carbon microspheres were innovatively synthesized using xylose as the carbon precursor under hydrothermal carbonization. A mechanism for the yolk–shell carbon microspheres formation was proposed. The associations between lignosulfonate and P123 led to the formation of mixed micelles. Owing to the highly branched structure and steric hindrance effect of lignosulfonate, lignosulfonate preferentially assembled at the outer position of double layers of micelles, while linear structure P123 located at the inner position. The xylose assembly process depended on the hydrogen bond interactions between xylose and P123/lignosulfonate soft templates, which do provide appropriate nucleation and growth sites for the assembled particles and affect the formation process simultaneously. What’s more, the xylose underwent dehydration, polymerization, and aromatization stages during the hydrothermal carbonization process until the nucleation took place, leading to the in situ formation of carbon particles. The formation mechanism is attributed to relatively complex synergistic effects and will be promising for guiding unique carbon materials synthesis. Additionally, the carbon materials showed good performance in their application in biochemistry and supercapacitor fields.
