KOPEC obtained a Korean patent on January 31 for ‘Vanadium/titania NOx catalyst at low temperature, and application/DeNOx methods thereof (Patent No. 0549778, Inventors: Hong Sung-ho, Lee Jun-yup, Hong Seok-ju, and Cho Sung-pill of Environment & Energy Research Group, Power Engineering Research Institute). This is an upgraded version of vanadium/titania-based catalyst with various non-stoichiometric compounds. 

The patented DeNOx catalyst developed by KOPEC are composed of meta-stable compounds with high chemical reactivity for the reduction of nitrogen oxide at low temperatures below 250℃, whereas other vanadium/titania (V₂O₅/TiO₂) catalysts are mostly composed of chemically stable compounds, and its proper operation temperature is relatively high as 300~400℃.

 Therefore the newly developed catalyst can remove nitrogen oxide at low temperatures like the previously patented catalyst (Patent No. 0549777). KOPEC was able to establish the uniqueness of low-temperature NOx catalyst by defining the characteristics of the materials for formulating various types of meta-stable compounds.

The Environment & Energy Research Group has achieved the outcome in the course of carrying out many government projects, and the DeNOx catalyst with the excellent NOx removal efficiency was developed. Furthermore, the newly patented low-temperature NOx catalyst is energy efficient. For this reason, KOPEC has applied for a patent in the , , , Europe, , , and Eurasia
