Hierarchical Porous Carbons for High-Rate Aqueous Supercapacitors: Tuning Pore Sizes by Molecular Design of Carbon Dots as Self-Templates.
Rational pore-size regulation is central to high-performance electric double-layer capacitors, yet carbon dots (CDs) self-templating often yields overly micropore-dominated carbons with limited high-rate capability. Here, we tailor CDs by combining polyethyleneimine with four organic acids and convert them into porous...
