Technological and Economic Aspects of Soil Bio/Phyto Remediation PROCEEDINGS VOLUME Lidar Remote Sensing for Industry and Environment Monitoring The design and synthesis of highly active non-noble metal oxide catalysts, such as transition-and rare-earth-metal oxides, have attracted significant attention because of their high efficiency and low cost and the resultant potential applications for the degradation of volatile organic compounds (VOCs).

The structure-activity relationships have been well-studied and used to facilitate design.
