Activated carbon prepared from catechol distillation residue for efficient adsorption of aromatic organic compounds from aqueous solution.

At present, activated carbon (AC) derived from industrial wastes has a great practical significance. In this work, residue activated carbon (RAC) was successfully synthesized from catechol distillation residue by a simple activation process based on two steps. The optimized RAC (RAC-800, activated at 800 °C) had high specific surface area (1800 m/g) and large total pore volume (0.

Well-Defined Cu O/Cu (BTC) Sponge Architecture as Efficient Phenolics Scavenger: Synchronous Etching and Reduction of MOFs in confined-pH NH ⋅H O.

Fabrication of low-dimensional nano-MOFs as well as nanoparticles/metal-organic frameworks (MOFs) hybrids has sparked new scientific interests but remains a challenging task. Taking Cu (BTC) as a proof of concept, it is demonstrated thats NH ⋅H O solution of a confined pH value can readily shape the bulk Cu (BTC) into nanoscale Cu (BTC) , beyond the need to control the crystal growth kinetics of MOFs. Adjusting the pH of NH ⋅H O within a much small range (10-11) allows fine tuning over the size and shape of nanoscale Cu (BTC) .
