摘要：

Technologies for the nitrate removal from drinking water and waste water will be required in the near future and the catalytic nitrate reduction is one of the most promising ones. To establish a technical-scale nitrate reduction a further improvement of the catalyst is necessary and new concepts should be introduced in the process. It is shown, that palladium-tin and palladium-indium catalysts can be much more suited for an efficient nitrate reduction than palladium-copper catalysts. Furthermore, two new innovative concepts are presented - the use of in situ buffering formic acid as reductant instead of hydrogen and the application of PVAL-encapsulated catalysts with superior diffusional properties - which may contribute to solve selectivity problems.
