Abstract
The electrochemical degradation of nitrobenzene in undivided and divided cell using Ti/SnO2-Sb2O5 anode was studied. The electrochemical degradation of nitrobenzene is of the results together by anode and cathode. Two general possible paths of the electrochemical degradation of nitrobenzene are proposed: (1) Nitrobenzene was first oxidized to p-nitrophenol. Then p-nitrophenol was degraded to hydroquinone, benzoquinone, maleic acid and oxalic acid, etc. Finally, all of the intermediates were oxidized into CO2 and H2O. (2) Nitrobenzene was mainly reduced to aniline at the cathode,aniline was degraded to 4-aminopheol, hydroquinone, benzoquinone and other intermediates at the anode, then all of the intermediates are oxidized till complete degraded and mineralized at last.

Advances of Heterocyclic Chemistry with Pesticide Activity
Global food safety and security will continue to be a global concern for the next 50 years and beyond. Plant diseases have had a significant impact on food safety and security throughout the entire food chain, from primary production to consumption. While conventional chemical pesticides have been traditionally used for ...read more
Carbohydrates conversion in biofuels and bioproducts
Biomass pretreatment, hydrolysis, and saccharification of carbohydrates, and sugars bioconversion in biofuels and bioproducts within a biorefinery framework. Carbohydrates derived from woody biomass, agricultural wastes, algae, sewage sludge, or any other lignocellulosic feedstock are included in this issue. Simulation, techno-economic analysis, and life cycle analysis of a biorefinery process are ...read more
Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
Chemistry and Biology of Carbohydrates
Carbohydrates are one of the most abundant natural products and are considered to be extremely important biomolecules for their ever-increasing impact on chemistry and biology. Their role in several important biological processes, notably energy storage, transport, modulation of protein function, intercellular adhesion, malignant transformation, signal transduction, viral, and bacterial cell ...read more
