Enhancement efficiency of catalyst -AgVO3/mpg-C3N4, in the preparation of vis light catalyst and for comparison ZnO,TiO2 and composite involved UV/Vis. Synthesis, characterized SAXS, EDX, SEM, TEM and N2 test activity under reliable condition in the deg of IBP. Reaction bi product checked by TOF-MS and contribution of Ros such as, OH, O2 by using scavenger. Result highly active catalyst obtained superior UV/Vis. efficiency of catalyst enhanced by mesoporous. Reason is improved dispersion catalyst on mesoporous access to catalyst surface. Porosity has miner impact efficiency .<eng>
