A purposely built integrated reactor, which comprised a drop tube and a moving bed assembly located at the bottom of the drop tube, combined rapid pyrolysis and in situ volatiles upgrading over char for the production of high-quality tar from coal. Rapid pyrolysis took place when coal particles flowed through the hot drop tube, and then the produce...

In this study, the covalent bonding of linear poly(ionic liquids (PILs) with covalent organic frameworks (COFs) was accessed by copolymerization of a vinyl-decorated COF with 4-vinylbenzyl chloride, followed by quaternization with tertiary amines. The resultant PIL-COF composite by anchoring a proper content of vinyl sites on the COF-based comonome...

Herein, we report the use of poly(3,4-ethylenedioxythiophene) functionalized ZIF-67 (PEDOT/ZIF-67) as a precursor for preparing an efficient and precious metal-free oxygen reduction reaction (ORR) catalyst. The PEDOT/ZIF-67 precursor is subjected to pyrolysis at 800 degrees C and subsequent acidic etching with 1 M HCl to form Co-N-S triple-doped po...
At present, the excessive use of sodium isobutyl xanthate (SIBX) in mineral processing has caused serious environmental problems, drawing ever-growing concern in China. A nitrogen and cerium co-doped TiO2-coated activated carbon (Ce/[email protected]) heterojunction were prepared through the sol-gel method to address these problems. The photocatalyst was c...

The non-toxic biologic material of expanded corn starch (ECS)-supported nitric acid (ECS-HNO3 and ECS-NH2-HNO3) has been prepared via simple procedures. Both the materials are used as heterogeneous catalysts for the selective aerobic oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF) with an up to 98% yield in gamma-butyrolactone...
