Abstract

<abstract abstract-type="toc"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <graphic position="anchor" id="ga" xlink:href="ark:/27927/pgjn30153q" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" />3D cauliflower-fungus-like graphene (CFG) with hierarchical mesoporous-structure synthesized directly from CO₂ exhibited an ultrahigh areal capacitance of 1.16 F cm⁻² at a high current density and reached a high efficient-mass-loading of 11.16 mg cm⁻². This solves a critical issue of sacrificing mass capacitance with increasing mass loading.</p> </abstract>
