“…In addition to high electron conductivity, carbon materials show ultra-high specific surface areas, e.g., activated carbon has a specific surface area of 2000 m 2 g À1 , which allows them to accommodate the main active species with a suitable mass load to achieve maximum reactant accessibility and exposure of catalytic sites, as seen in Pt/C. 74,75 Therefore, carbon materials are regarded as a promising support for constructing oxygen electrocatalysts.…”

This work studied the synthesis of activated carbons (ACs) from olive tree pruning waste since the recovery of this abundant residue for producing AC is a sustainable and environmentally friendly alternative. The physical and KOHchemical activation processes were compared and analyzed to obtain an appropriate carbon for the adsorption of CO 2 . Highly microporous carbons were obtained after KOH chemical activation that exhibit high surface area (3526 m 2 g −1 ), micropore volume (1.20 cm 3 g −1 ), and total volume (1.79 cm 3 g −1 ). The equilibrium and kinetic behavior of carbons for CO 2 adsorption were studied using Langmuir, Freundlich, and Temkin models for the isotherms and pseudo-first-order and pseudo-second-order models for the kinetics. The chemically activated carbon was found to be the most appropriate for the capture of CO 2 at low and high CO 2 pressures, showing an adsorption capacity of 5.1 mmol g −1 at 0 °C and 1 bar. The estimated isosteric heat indicates that the CO 2 adsorption process was feasible and confirms the pure physical adsorption of CO 2 . The chemically activated carbon allowed ten reuse cycles, maintaining the capture capacity. These results confirm that ACs from olive tree pruning residue have suitable capacity and stability for application as CO 2 adsorbents.

“…Carbon materials, such as graphene [3], carbon nanotubes [4], carbon fibers [5], and activated carbons (ACs) [6,7], have played an essential role in the field of energy storage. Among them, ACs have been widely used and studied for applications in lithium-ion batteries [8], sodium-ion batteries [9], supercapacitors [10], and other fields due to their large specific surface area (SSA), good chemical stability, and considerable porosity [11]. Several precursors can be used to make ACs, including coal, pitch, polymers, biomass materials, and so on.…”

The development and utilization of biomass and agroforestry processing byproducts for high-value applications have been an important topic in the field of renewable materials research. Based on this, a two-step microwave hydrothermal pre-carbonization and KOH activation method was proposed to synthesize tannin-based activated carbons with a high specific surface area, hierarchical pore structure, and good electrochemical performance. The microstructure, texture properties, and physicochemical characteristics were investigated. The results show that the prepared tannin-based activated carbons presented a hierarchical pore structure (micro-and mesopores) with a specific surface area as high as 997.46 m 3 g −1 . The electrochemical analysis shows that the tannin-based activated carbons have good wettability and charge transfer rates. Under the three-electrode system with 6 M KOH as the electrolyte, the active material TAC 600-4 had a maximum specific capacitance of 171 F g −1 at 0.5 A g −1 . As the current density increases to 10 A g −1 , the specific capacitance can still be maintained at 149 F g −1 , indicating a good rate capability. Therefore, the specific surface area and pore size of tannin-based activated carbons can be effectively adjusted by the alkali/carbon ratio, making it a promising supercapacitor electrode material and providing a new method for the high-value development of tannins in the field of electrochemical energy storage.
