A comprehensive review on green perspectives of electrocoagulation integrated with advanced processes for effective pollutants removal from water environment.

The rapidly expanding global energy demand is forcing a release of regulated pollutants into water that is threatening human health. Among various wastewater remediating processes, electrocoagulation (EC) has scored a monumental success over conventional processes because it combines coagulation, sedimentation, floatation and electrochemical oxidation processes that can effectively decimate numerous stubborn pollutants. The EC processes have gained some attention through various academic and industrial publications, however critical evaluation of EC processes, choices of EC processes for various pollutants, process parameters, mechanisms, commercial EC technologies and performance enhancement via other degradation processes (DPs) integration have not been comprehensively covered to date.

Reduced graphene oxide -MnO nanocomposite for CO capture from flue gases at elevated temperatures.

The newly prepared reduced graphene oxide-MnO (rGO-MnO) nanocomposite has exhibited highly selective CO adsorption from gaseous mixtures at elevated temperatures. The Mn basic sites are scattered over the rGO-MnO nanocomposite which produce an effective BET surface area of 710 m g for selective CO capture. The selective adsorption of CO (5.
