CoTiO < inf > 3 < /inf > is found to play important roles in enhancing the visible light-harvesting ability of the composite and increasing electron-hole separation efficiency due to the hybrid effect between Ag < inf > 3 < /inf > VO < inf > 4 < /inf > and CoTiO < inf > 3 < /inf > . The indirect probe experiments reveal that CoTiO < inf > 3 < /inf > /Ag < inf > 3 < /inf > VO < inf > 4 < /inf > heterostructure provides large amount of active species, therefore a high photocatalytic activity could be obtained. The results clearly suggest that the photocatalytic MB degradation over this hybrid catalyst is mainly governed by direct hole oxidation. 2018-01-24T04:39:15Z 2018-01-24T04:39:15Z 2015-09-05 Journal 10957103 00219797 2-s2.0-84930941838 10.1016/j.jcis.2015.05.025 https://www.scopus.com/inward/record.uri?partnerID=HzOxMe3b&scp=84930941838&origin=inward http://cmuir.cmu.ac.th/jspui/handle/6653943832/44195
