i am working on BiOBr/UIO-66-NH2 for photocatalytic RhB degradation.i used this MOF alone for RhB degradation so i didn't get a good result but when i add some ethanol upto 1mM i get a good result upto 80%. i search a lot in literature the role of Ethanol regarding this MOF in photocatalytic degradation to explain the mechanism but i didnot find some related result?
