Boron nitride is maximum explored material these days because of its extraordinary optical, mechanical, chemical properties. The material is so sensitive to its structure that slight change in its lattice parameter unexpectedly change its properties like change in c/a ratio, change the material form soluble in water to insoluble. Present study deals with preferentially grown nanostructured BN along (002) and (102) plane. This preferentially growth is one of the major parameter for its extraordinary response to change light energy to chemical energy. As a result a material which has no catalytic activity when grown along (002) plane. When mixed with SnO2 (tetragonal) is dissociated into smaller sheets and reorient to (102) plane. The SnO2 particles attached both side of BN sheets to provide more surface area to make this material extra ordinary catalyst. This preferentially grown BN/SnO2 composite along (102) degrades methyl orange (MO) in just 7 minutes to 92% of its original value. This efficiency shows that preferentially BN based composite is promising candidate for solar energy conversion.
