It is pointed out that direct electro-deoxidation,a new process for preparing single metal and alloy,is characterized by low cost,less energy consumption,less pollution and simple process.

Preliminary study on the mechanism of ZrO_2 direct electrodeoxidation;

Preparation of zirconium by direct electrodeoxidation;

An organic composite denitrification agent composed of ethyl lactate was prepared,and the removal effect of ammonia nitrogen by organic composite denitrification agent/air-stripping was compared with that by traditional air-stripping method.

Molten salt electrolysis materials used in electro-deoxiedation;

Synthesis of 2,3,5-trimethylhydroquinone by direct oxidation;

p-Bromobenzaldehyde was synthesized from p-bromotoluene by direct oxidation with manganese sesquioxide The factors affecting the yields of p-bromobenzaldehyde were investigated.

The paper reviews the development of direct oxidation process for sulfur recovery, with the emphasis on direct oxidation processes which are more successful recently, and puts forth the necessity for developing the processes.

In an H type of electrolytic cell, with benzene as the starting material, H_2SO_4 as the supporting electrolyte, PbO_2 as the anode material, graphite as the cathode material, para quinone was synthesized by means of the direct electrooxidation technique.
