Solid-State Carbon Dots with Red Fluorescence and Efficient Construction of Dual-Fluorescence Morphologies.
Stable solid-state red fluorescence from organosilane-functionalized carbon dots (CDs) with sizes around 3 nm is reported for the first time and a novel method for the efficient construction of dual-fluorescence morphologies is first reported. Expand
Ultrahigh-surface-area hierarchical porous carbon from chitosan: acetic acid mediated efficient synthesis and its application in superior supercapacitors
The development of an effective route to high-performance carbonaceous electrode materials derived from low-cost biomass is critical but remains challenging for supercapacitors. Here we propose a new… Expand
Hierarchical porous carbons: design, preparation, and performance in energy storage
Hierarchical porous carbons (HPCs) possess a multimodal pore size distribution of micro-, meso-, and/or macropores, and thus show high electrochemically accessible surface area, short diffusion… Expand
Direct fabrication of bimodal mesoporous carbon by nanocasting
Abstract Bimodal mesoporous carbons were successfully prepared by a simple one-step templating method. The template of large mesopores in our method is the in situ formed silica nano-agglomerate from… Expand
