Enhancing effect of cobalt phthalocyanine dispersion on electrocatalytic reduction of CO towards methanol.

This paper focuses on enhancing the performance of electrocatalytic CO reduction reaction (CORR) by improving the dispersion of cobalt phthalocyanine (CoPc), especially for the methanol formation with multi-walled carbon nanotubes (CNTs) as a support. The promising CNTs-supported CoPc hybrid was prepared based on ball milling technique, and the surface morphology was characterized by means of those methods such as scanning electron microscopy (SEM), Fourier transform infrared spectrometer (FT-IR) and X-ray photoelectron spectra (XPS). Then, the synergistic effect of CNTs and ball milling on CORR performance was analyzed by those methods of cyclic voltammetry (CV), linear sweep voltammetry (LSV), electrochemical impedance spectroscopy (EIS), gas chromatography (GC), and proton nuclear magnetic resonance spectroscopy (HNMR).

Single and binary adsorption of heavy metal ions from aqueous solutions using sugarcane cellulose-based adsorbent.

A high efficient and eco-friendly sugarcane cellulose-based adsorbent was prepared in an attempt to remove Pb, Cu and Zn from aqueous solutions. The effects of initial concentration of heavy metal ions and temperature on the adsorption capacity of the bioadsorbent were investigated. The adsorption isotherms showed that the adsorption of Pb, Cu and Zn followed the Langmuir model and the maximum adsorptions were as high as 558.

Experimental study on elemental mercury removal by diperiodatonickelate (IV) solution.

A novel method has been developed to remove elemental mercury from simulated flue gas by a diperiodatonickelate (IV) solution. The influencing factors, such as diperiodatonickelate (IV) concentration, reaction temperature, solution pH, the initial Hg(0) concentration, SO₂ concentration and NO concentration were investigated at a bubbling reactor. In the presence of SO₂ and NO, removal efficiency of 86.

Simultaneous desulfurization and denitrification from flue gas by Ferrate(VI).

An innovative semidry process has been developed to simultaneously remove NO and SO₂ from flue gas. According to the conditions of the flue gas circulating fluidized bed (CFB) system, ferrate(VI) absorbent was prepared and added to humidified water, and the effects of the various influencing factors, such as ferrate(VI) concentration, humidified water pH, inlet flue gas temperature, residence time, molar ratio of Ca/(S+N), and concentrations of SO₂ and NO on removal efficiencies of SO₂ and NO were studied experimentally. Removal efficiencies of 96.
