Liquefiable biomass-derived porous carbons and their applications in CO₂capture and conversion

Abstract

Biomass-derived porous carbons (BPCs) have been explored as adsorbents for CO2 capture and catalysts for CO2 conversion, showing great potential in helping achieve "negative carbon emissions." Traditionally, BPCs are derived...

Recycling and repurposing of waste carbon nanofiber polymers: a critical review

“…With the maturation of electrospinning technology, the large-scale production of continuous nanofibers, ranging from twenty to several hundred nanometers, has become feasible. [18][19][20] By manipulating electrospinning parameters, solution or melt compositions, and environmental conditions, it is possible to precisely engineer and adjust customized porous topologies, including intra-fiber pores, surface pores, and inter-fiber pores, on the nano and micro scales, thus paving the way for enhanced performance in various applications. [21][22][23] As shown in Fig.…”

Catalytically Active Carbon for Oxygen Reduction Reaction in Energy Conversion: Recent Advances and Future Perspectives

“…In addition to modulating different preparation methods such as pyrolysis, [ 41 , 42 , 43 ] hydrothermal carbonization, [ 44 , 45 , 46 ] liquefied carbonization, [ 47 , 48 , 49 ] etc., the modification process should also be considered. For one thing, various heteroatoms (e.g., nitrogen (N), [ 50 , 51 , 52 ] phosphorus (P), [ 53 , 54 ] sulfur (S), [ 55 , 56 ] boron (B), [ 57 , 58 ] and fluorine (F), [ 59 ] etc.)…”

Preparation of Magnetic Nano-Catalyst Containing Schiff Base Unit and Its Application in the Chemical Fixation of CO2 into Cyclic Carbonates

“…In the whole cycloaddition reaction, experimental and theoretical studies have shown that the activation and ring-opening of epoxides are the decisive step [7]. Catalysts for epoxide activation such as metal oxides [8], metal salts [9], metal complexes [10], metal-organic skeleton materials [11], rare earth complexes [12], supported organometallic complexes [13], COF [14], small molecules [15], porous carbon from biomass [16], plasma [17], and Rhodamine dyes [18] have been reported. Among them, metal ion modified catalysts account for a large proportion, and the metals involved are potassium, calcium, magnesium, aluminum, zinc, iron, copper, niobium, chromium, zirconium, cobalt, lanthanum, indium and so on.…”
