Porous carbon nanosheets with open 2D nanostructure have been considered a desirable and high‐efficient energy‐storage material. Herein, N, S, P co‐doped interconnected porous carbon nanosheets (CPCNs) with high defect density and open 2D ultrathin nanostructure are prepared by using a cork‐shaped soybean aerogel as carbon source. A reasonable design of the preparation technology controls the formation of the distinctive and ordered structure of intermediates during the synthetic process. The as‐prepared CPCN material is made of interconnected nanosheets with a thickness of 4.9 nm and have a maximum N‐dopant content of 5.83 at. % and a high specific surface area of 3586 m2 g−1. Due to the synergistic effects of the features, the CPCN electrode for supercapacitors has a high capacitance of 427 F g−1 with a long cycling stability of 97.42 % after 10 000 cycles. For lithium‐ion batteries, the CPCN material also exhibits an excellent capacity of 1220 mAh g−1 at 100 mA g−1 with a high rate capability and cycling stability. Moreover, a scenario through using CPCN to enhance the electrochemical performance of nano‐inorganic material proves a high scalability in the application for the products.

The conversion of discarded biomass into biomass activated carbon is a major trend in its high-value use. Herein, a template-free, ecofriendly, simple, and scalable-produced hierarchical ordered porous WO 3 −C (HOP-WC) is creatively fabricated through one-step glue milling and carbonization-activation. Owing to the optimized porous structure, the resulting HOP-WC-800 presents a large specific surface area (1964.9 m 2 g −1 ) and high pore volume (1.56 cm 3 g −1 ). As a supercapacitor electrode, it displays a high capacitance of 554.6 F g −1 at 0.5 A g −1 . Moreover, only around 10% capacitance fading is observed after 10000 cycles at a scan rate of 500 mV s −1 . As an electrocatalyst material, the Pt (20 wt %) modified HOP-WC-800 electrode exhibits an excellent electrocatalytic performance toward methanol oxidation. It is found that the specific current of Pt-mass activity is high as 541.4 mA mg −1 in the potential range of 0.6−0.8 V. In a word, the strategy of constructing hierarchical ordered porous carbon-based materials via one-step glue milling and carbonization-activation offers a great referential value for developing other multifunctional materials, such as fallen leaves, withered grass, and other waste biomass materials.
