In recent years, photocatalytico oxidation processes with ultra violet (UV) radiation and semiconductor photocatalyst like titanium dioxide (TiO2) and zinc oxide (ZnO) have gained immense research interest as an effective wastewater purification method because of its efficacy in decomposing and mineralising the hazardous organic pollutants as well as the opportunity of utilizing the solar UV an...

Methanol electrochemical oxidation in a direct methanol fuel cell (DMFC) is considered to be an efficient pathway for generating renewable energy with low pollutant emissions. NiO−CuO and Ni0.95Cr0.05O2+δ thin films were synthesized using simple dip-coating method tested the electro-oxidation of methanol. These electrocatalysts characterized by X-ray diffraction spectroscopy (XRD), photoelectro...

This work studied the removal of phenol from industrial effluents through catalytic ozonation in presence granular activated carbon a continuous fixed-bed reactor. Phenol was chosen as model pollutant because its environmental impact and high toxicity. Based on evolution total organic (TOC) concentration, kinetic proposed to study effect operational variables combined adsorption–oxidation (Ad/O...

Ozone and hydroxyl radical (*OH) reaction kinetics were measured for 14 antibacterial compounds from nine structural families, to determine whether municipal wastewater ozonation is likely to result in selective oxidation of these compounds' biochemically essential moieties. Each substrate is oxidized by ozone with an apparent second-order rate constant, k''(O3,app) > 1 x 10(3) M(-1) s(-1), at ...

Photoinduced reactive oxygen species (ROS)‐based pollutant removal is one of the ideal solutions to achieve conversion solar energy into chemical and thus address environmental pollution. Here, earth‐abundant CaCO 3 ‐decorated g‐C N 4 (g‐C labeled as CN, sample CN‐CCO) has been constructed by a facile thermal polymerization method for safe efficient photocatalytic NO removal. The decorated “tra...

In this paper, we assume that a professional pollutant treatment enterprise treats all of the pollutants emitted by multiple small and medium-sized enterprises (SMEs). In order to determine the treatment price, SMEs can bargain with the pollutant treatment enterprise individually, or through forming alliances. We propose a bargaining game model of centralized pollutant treatment to study how th...
