A review of the current literature shows there is no clear consensus regarding reaction mechanisms air-borne aromatic compounds such as toluene by photocatalytic oxidation. Potential oxidation reactions over TiO2 or TiO2-based catalysts under ultraviolet and visible (UV/VIS) illumination are most commonly considered for removal these pollutants. Along pathways from a model pollutant, toluene, t...

Controllable CO2 Reduction In article number 2207234, Ruiting Xue, Jun Xie, and co-workers report a silver quantum dot (Ag-QDs) photocatalyst capable of tunneling photocatalytic reaction using surface plasmons. Ag-QDs can be selectively regulated as oxidation or reduction sites drive pollutant under entire solar. This technology is expected to restore ecological environment solve energy crisis.

Background: Electro-oxidation is developed as an electrochemical method to overcome the problems of  the conventional  decolorization technologies and is an appropriate alternative for the treatment of colored wastewater from various industries. The purpose of this study was to evaluate the efficiency of the electrochemical oxidation process in  removal  of chemical oxygen demand (COD) and Acid...

he Clean Air Act (CAA) Amendments of 1990 are inT tended to reduce emissions of volatile organic compounds (VOCs) by 70 to 90%. They specifically designate 189 compounds as hazardous air pollutants (HAPs). The EPA estimates that the aerospace industry generates 208,000 tons per year of HAPs plus an additional 145,000 tons per year of VOCs. Maximum Achievable Control Technology (MACT) standards ...

This paper reviews trace metal dynamics in floodplain soils using the Elbe floodplains in Germany as an example of extraordinary importance because of the pollution level of its sediments and soils. Trace metal dynamics are determined by processes of retention and release, which are influenced by a number of soil properties including pH value, redox potential, organic matter, type and amount of...

Organic pollutants, especially those found in water bodies, pose a direct threat to various aquatic organisms as well as humans. A variety of different remediation approaches, including chemical and biological methods, have been developed for the degradation of various organic pollutants. However, comparative mechanistic studies of pollutant degradation by these different systems are almost non...

Catalytic persulfate technology is a new type of catalytic that has been extensively studied in recent years. Among them, the copper and silver materials synthesized by microwave assist have broad application prospects are class catalysts with excellent performance, environmental friendliness, stable structure. This article introduces material loaded metal activated carbon, analyzes mechanism o...
