“…To our best knowledge, the studies of MoO 3 properties are mainly concentrated on the gas sensing performance, [2,10,18,20] lithium-ion batteries, [3,6,9,12] field emission [1,5,21] photochromic property. [4,8,22] There have been few reports on the study of photocatalytic performance of MoO 3 for degrading organic dye. [23] Moreover, the systematically comparative study of MoO 3 photocatalytic property (including h-MoO 3 and a-MoO 3 ) and their mechanism investigation are also seldom reported.…”
