Coal tar pitch (CTP), a by-product of coking industry, has unique molecule structure comprising an aromatic nucleus and several side chains bonding on this graphene-like nucleus, which is very similar to the graphene quantum dots (GQDs). Based perception, we develop facile approach convert CTP GQDs only by oxidation with hydrogen peroxide under mild conditions. One three layers, monodisperse narrow size distribution 1.7 ± 0.4 nm, are obtained at high yield (more than 80 wt. %) from CTP. The...
Graphene quantum dots (GQDs), a newly emerging zero-dimensional material, have achieved widespread interest in energy storage applications. However, the complicated preparation processes of GQDs involving harsh reagents/conditions, cumbersome purification procedures, or costly precursors hinder their practical use. Herein, we reveal low-cost and eco-friendly solvothermal method to obtain an FeS@GQDs composite, with coal tar pitch (CTP) as ″natural GQDs″. When evaluated anode material...
Abstract Groundwater pollution is regarded as one of the most serious environmental risks related to underground coal gasification (UCG). In this paper, two kinds high efficient phenol degrading strains were isolated from activated sludges, which obtained coking wastewater and domestic sewage, named JC WX correspondingly. The bacteria identified by a combination method physiological biochemical analyses 16SrDNA sequencing. total organic carbon (TOC) pollutants in gas washing water produced...
A type of nanomesoporous modified red mud (MRM) catalyst was prepared and utilized for catalytic methane decomposition (CMD) to produce hydrogen. The modification process significantly simplified the mineral composition (RM); in meantime, physical chemical structure RM changed. TEM images suggested that MRM a kind material assembled by number uniformly nanoscale particles, BET results showed pore size distributions were ranged from 3 12 nm, specific surface area total volumes improved 8.00 m...

From the health and environmental point of view, control soluble metal elements organic compounds in underground coal gasification (UCG) by‐product is great importance for groundwater protection. Unlike leaching ash as well normal pressure, trace organics from UCG semi‐coke into confined has received little concern. In this research, model test Inner Mongolia lignite was performed, obtained then soaked by applying stainless steel column at 0.5, 1.0, 1.5 2.0 MPa with nitrogen pressurizing...
High-value materialized clean utilization of coal and anode materials for sodium-ion batteries (SIBs) with large reversible capacity rapid kinetics are the direction green low-carbon economic development. Herein, anthracite-based expanded graphite (AEG) was prepared via a liquid-phase oxidation intercalation-rapid thermal reduction method by employing homemade (AG) as SIBs. The unique morphological structure AEG provides superior structural stability sodium storage behavior dominated...
