“…According to the GCD results (Figures a and S10a–c), the offered energy densities of the assembled C|C, C|MnO 2 , and C|Zn devices are shown in Figure b. As seen from the Ragone plots, C|Zn provides 84.5 Wh kg –1 at a power density of 1000 W kg –1 much higher than those of C|C (21.2 Wh kg –1 ) and C|MnO 2 (23.6 Wh kg –1 ), which is almost 4 times higher than that of the C|C and the referred symmetric supercapacitors, ,− demonstrating the advantages of the PPE concept with an impressive energy density. With the increase of power density, C|MnO 2 shows the relatively poor rate performance, and C|C and C|Zn remain more stable and flat energy densities, indicating the excellent rate performance of the PPE system.…”

Herein, we propose a new concept of energy storage system composed of a nonpolarized electrode and a polarized electrode (PPE) with an impressive energy density. It offered nearly 4 times higher energy density than that of carbon-based supercapacitor. Among the suggested potential PPE system, we introduced an electrodeposited nanozinc on the copper foam as the nearly nonpolarized electrode and a Zn-2,5dihydroxyterephthalic acid (DHTA) metal−organic framework (MOF)derived activated porous carbon as a nearly polarized electrode in KOH-ZnO electrolyte to constitute the C|Zn PPE system prototype. The C|Zn system achieved an impressive energy density of 84.5 Wh kg −1 at 1000 W kg −1 , 4 times higher than that of the C|C supercapacitor. It also shows a high capacitance retention rate of 94.5% at 10 A g −1 after 10 000 cycles. Therefore, the amazing results indicate that the PPE energy system integrates the advantages of supercapacitors and secondary batteries. It will be a promising and effective energy device for higherperformance electric vehicles.

“…MOFs are commonly used as precursors for the synthesis of porous carbon for supercapacitor applications with improved stability and conductivity [20,21]. As reported by Jiang and co-5 workers, nitrogen-doped porous carbon derived from Al-based MOF displays a specific capacitance of 332 F g −1 at 1 A g −1 with a capacitance retention of 97.8% after 100,000 charging/discharging cycles [20].…”

However, carbonization of MOFs needs high temperature and involves large amount of energy, which may not be feasible always.…”

“…This method offers a fresh potential approach to combining heteroatomcontaining polymers with metal−organic backbones to create novel architectures and unique heteroatom-doped porous carbon materials for power supercapacitors. 122 Zeolites' large particular surface area, narrow pore size distribution, and strong persistence make them popular industrial catalysts and adsorbents. 123 However, in actual trapping, the adsorption of CO 2 and H 2 O by zeolites results in intense competition, and the majority of zeolites are moisturesensitive, which can cause adsorbent poisoning.…”

High emission of carbon dioxide (CO 2 ) has caused CO 2 levels to reach more than 400 ppm in air and led to a serious climate problem. In addition, in confined spaces such as submarines and aircraft, the CO 2 concentration increase in the air caused by human respiration also affects human health. In order to protect the environment and human health, the search for highperformance adsorbents for carbon capture from high and low concentration gas is particularly important. Porous carbon materials, possessing the advantages of low cost and renewability, have set off a boom in the research of porous adsorbents, which have the opportunity to be utilized on a large scale for industrial carbon capture in the future. In this review, we summarize the recent research progress of porous carbons for carbon capture from flue gas and directly from air in the last five years, including activated carbon (AC), heteroatom-modified porous carbon, carbon molecular sieves (CMS), and other porous carbon materials, with a focus on the effects of temperature, water content, and gas flow rate of industrial flue gas on the performance of porous carbon adsorbents. We summarize the preparation strategies of various porous carbons and seek environmental friendly porous carbon materials preparation strategies under the premise of improving the CO 2 adsorption capacity and selectivity of porous carbon adsorbents. Based on the effects of real industrial flue gas on adsorbents, we provide new ideas and evaluation methods for the development and preparation of porous carbon materials.
