PHOTOCATALYTIC SYNTHESIS AND PHOTODECOMPOSITION OF AMMONIA OVER SrTiO3 AND BaTiO3 BASED CATALYSTS

Photocatalytic synthesis of ammonia from N2 and H2O and its photodecomposition were investigated over SrTiO3 and BaTiO3 based catalysts. It was demonstrated that the yield of NH3 formation increased markedly by the use of RuO2 and NiO doped three component catalysts and that photodecomposition of NH3 was coupled with photodecomposition of H2O.
