Oxygen-enriched hierarchical porous carbon from sawdust with enhanced supercapacitive performance
Abstract Wood processing will produce a lot of sawdust, which will not only pollute the environment but also cause a waste of resources. So, it is still a challenge to make high value-added utilization of sawdust. Herein, we designed a novel method for the preparation of oxygen-enriched hierarchical...

| 520 | |a Abstract Wood processing will produce a lot of sawdust, which will not only pollute the environment but also cause a waste of resources. So, it is still a challenge to make high value-added utilization of sawdust. Herein, we designed a novel method for the preparation of oxygen-enriched hierarchical porous carbons (OHPCs) from sawdust by using magnesium chloride coupled with potassium carbonate activation. The prepared OHPC maintains the natural pore structure of sawdust, which supplies a lot of channels for rapid ion transport. Besides, the abundant oxygen-containing functional groups inside the OHPC generate a pseudo-capacitor by the redox to improve the capacitance of OHPC electrodes. As a result, OHPC shows high electrochemical performance, e.g., high-specific capacitance of 324.9 F $ g^{−1} $ at 0.05 A $ g^{−1} $, excellent rate property of 231.3 F $ g^{−1} $ at 20 A $ g^{−1} $, and outstanding cycle life at 2 A $ g^{−1} $ of 96.9% after 16,000 cycles. The excellent electrochemical performance shows that OHPC materials can be used as an electrode for energy storage and conversion devices. | ||

Abstract Wood processing will produce a lot of sawdust, which will not only pollute the environment but also cause a waste of resources. So, it is still a challenge to make high value-added utilization of sawdust. Herein, we designed a novel method for the preparation of oxygen-enriched hierarchical porous carbons (OHPCs) from sawdust by using magnesium chloride coupled with potassium carbonate activation. The prepared OHPC maintains the natural pore structure of sawdust, which supplies a lot of channels for rapid ion transport. Besides, the abundant oxygen-containing functional groups inside the OHPC generate a pseudo-capacitor by the redox to improve the capacitance of OHPC electrodes. As a result, OHPC shows high electrochemical performance, e.g., high-specific capacitance of 324.9 F $ g^{−1} $ at 0.05 A $ g^{−1} $, excellent rate property of 231.3 F $ g^{−1} $ at 20 A $ g^{−1} $, and outstanding cycle life at 2 A $ g^{−1} $ of 96.9% after 16,000 cycles. The excellent electrochemical performance shows that OHPC materials can be used as an electrode for energy storage and conversion devices.

So, it is still a challenge to make high value-added utilization of sawdust. Herein, we designed a novel method for the preparation of oxygen-enriched hierarchical porous carbons (OHPCs) from sawdust by using magnesium chloride coupled with potassium carbonate activation. The prepared OHPC maintains the natural pore structure of sawdust, which supplies a lot of channels for rapid ion transport. Besides, the abundant oxygen-containing functional groups inside the OHPC generate a pseudo-capacitor by the redox to improve the capacitance of OHPC electrodes. As a result, OHPC shows high electrochemical performance, e.g., high-specific capacitance of 324.9 F $ g^{−1} $ at 0.05 A $ g^{−1} $, excellent rate property of 231.3 F $ g^{−1} $ at 20 A $ g^{−1} $, and outstanding cycle life at 2 A $ g^{−1} $ of 96.9% after 16,000 cycles. The excellent electrochemical performance shows that OHPC materials can be used as an electrode for energy storage and conversion devices.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Oxygen-enriched hierarchical porous carbon</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Supercapacitor</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Sawdust</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shao, Yutian</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhou, Shoubiao</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Ionics</subfield><subfield code="d">Berlin : Springer, 1995</subfield><subfield code="g">29(2022), 2 vom: 29.

Oxygen-enriched hierarchical porous carbon from sawdust with enhanced supercapacitive performance |
| abstract |
Abstract Wood processing will produce a lot of sawdust, which will not only pollute the environment but also cause a waste of resources. So, it is still a challenge to make high value-added utilization of sawdust. Herein, we designed a novel method for the preparation of oxygen-enriched hierarchical porous carbons (OHPCs) from sawdust by using magnesium chloride coupled with potassium carbonate activation. The prepared OHPC maintains the natural pore structure of sawdust, which supplies a lot of channels for rapid ion transport. Besides, the abundant oxygen-containing functional groups inside the OHPC generate a pseudo-capacitor by the redox to improve the capacitance of OHPC electrodes. As a result, OHPC shows high electrochemical performance, e.g., high-specific capacitance of 324.9 F $ g^{−1} $ at 0.05 A $ g^{−1} $, excellent rate property of 231.3 F $ g^{−1} $ at 20 A $ g^{−1} $, and outstanding cycle life at 2 A $ g^{−1} $ of 96.9% after 16,000 cycles. The excellent electrochemical performance shows that OHPC materials can be used as an electrode for energy storage and conversion devices. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2022.
