Summary: This paper presents a top-down templating strategy for the synthesis of functional porous carbon materials with high porosity and desired chemical functionalities. The porosity and heteroatom doping of the carbon materials can be controlled by varying the organic precursors and metal oxides. The strategy is also applicable for the preparation of carbon-based single-atom catalysts with iron-nitrogen sites.

Summary: Hydrothermal carbonization can convert bamboo shoot shells into hierarchical porous carbons, showing excellent adsorption capacity for dyes like Rhodamine B (RhB). The maximum adsorption capacity for RhB can reach up to 5398 mg/g due to the synergistic effects of porosity, pyrrolic-N configurations, and hierarchical structure.

Summary: Dyes containing wastewater is produced in large quantities by various industries. Graphene and graphene-based materials are attractive adsorbents for dye removal due to their high surface areas and strong pi-pi interactions. A simple and economical method of producing graphene-like carbon using biomass pyrolysis has been investigated. Cellulose-derived graphene-like carbon (CGLC) was obtained through pyrolysis with FeCl3/ZnCl2, and its adsorption capacity for cationic and anionic dyes was studied. The CGLC showed high adsorption capacities for both Rhodamine B and Congo Red, indicating its potential as an efficient adsorbent for dye removal.

Summary: Self-templating is an easy method to synthesize porous carbons through direct pyrolysis of organic metal salts. However, the method usually has low yields and limited specific surface areas due to the low activity of metal cations. In this study, cesium acetate is used as the precursor to produce oxo-carbons with large specific surface areas, high pore volume, adjustable oxygen contents, and high yields. The oxo-carbons show exceptional CO2 uptake and supercapacitor performance. This research helps to understand and design materials using organic solid-state chemistry, which is still rare.

Summary: Highly porous activated carbons were synthesized using sustainable precursors and chemical activators through the mechanochemical salt-templating method, showing diverse structural and physicochemical characteristics with specific surface areas ranging from 1190 m(2)center dot g(-1) to 3060 m(2)center dot g(-1). These carbons exhibited high H-2 and CO2 adsorption capacities, with the most microporous carbon showing a CO2 uptake capacity as high as 6.4 mmol center dot g(-1) at 1 bar and 0 degrees C. The activated carbons also displayed exceptional thermal stability, making them attractive for adsorption and catalysis applications.

The composite adsorbent exhibited a high specific surface area and pore volume, leading to effective adsorption of tetracycline (TC) pollutants in an aqueous solution. The adsorption process followed the second-order kinetic model and the adsorption isotherms fit well with the Tempkin model, indicating electrostatic interaction, 7C-7C stacking, and hydrogen bonding played an important role in the superior adsorption performance. Moreover, the adsorbent showed good stability and reusability.
