“Win‐Win” Structural Engineering of Chinese Herb Residues‐Derived Porous Graphitic Carbons: Decoupling the Porosity‐Graphitization Antagonism for Ultrahigh‐Rate Supercapacitors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work proposes a strategy that overcomes the porosity‐graphitization antagonism in carbon materials, converting Sargentodoxa cuneata residue into porous graphitic carbons to enable sustainable, high‐performance energy storage from biomass waste. The antagonism between porosity and graphitization critically limits carbon supercapacitor performance ...

Sustainable Upcycling of Office Waste Paper Into Cobalt/Carbon Aerogels for Highly Efficient Microwave Absorption

open access: yesElectron, EarlyView.
Co/C aerogels (Co/CAs) are successfully fabricated with office waste paper (OWP) as the raw material by loading ZIF‐67 crystals. The optimal sample exhibited an effective absorption bandwidth of 5.6 GHz, which outperforms many biomass‐derived microwave absorbing materials.
