This communication presented the chlorination-volatilization of cobalt using calcium chloride. Effects of variables on the cobalt volatilization rate were investigated, including the flow rate, oxygen partial pressure, and water vapor content of the carrier gas, the roasting time, and the temperature. It was found that the chlorination of cobalt ox...

Thiocyanate leaching is an efficient and environmentally friendly method to extract gold due to fast leaching speed, excellent reaction selectivity and slight environmental risks, but thiocyanate is easily oxidized to decompose by oxidant in the leaching process, resulting in large consumption of leaching agent. In this work, synergistic leaching e...

The direct chlorination of C-H bonds has received considerable attention in recent years. In this work, a metal-free protocol for hydrocarbon C-H bond chlorination with commercially available N-chlorosuccinimide (NCS) catalyzed by N-hydroxyphthalimide (NHPI) with 2,3-dicyano-5,6-dichlorobenzoquinone (DDQ) functioning as an external radical initiato...

Electrocatalytic water splitting into H-2 and O-2 is a key technology for carbon-neutral energy. Here, we report a modular materials design leading to noble metal-free composite electrocatalysts, which combine high electrical conductivity, high OER and HER reactivity and high durability. The scalable bottom-up fabrication allows the stable depositi...

In this study, quaternized chitosan microspheres (QCMS) were prepared and their adsorption performance of Acid Red 18 from aqueous solution was studied. Equilibrium was attained within 120 minutes and maximum removal of 94.06% was achieved. Langmuir and Freundlich isotherm models have been investigated. The maximum capacity obtained from the Langmu...
