Boron nitride (BN) has been explored these days because of its extraordinary optical, chemical and mechanical properties. BN is sensitive to its crystal structure that slight change in lattice parameters enormously change its properties. Present study deals with synthesis, characterization as well as photocatalytic applications of BN-based composite. When BN was mixed with SnO₂ having tetragonal crystal structure, dissociation into smaller sheets occurred and the material oriented to (102) plane. SnO₂ particles attached both sides of BN sheets provided high surface area which make the material suitable for catalytic process. Presence of large number of active sites leads to the formation of hydroxyl radicals in BN/SnO₂ composite which helps during degradation of organic and colourless pollutants i.e. methyl orange dye up-to ∼92% under 7 minutes and salicylic acid in 40 minutes to ∼82%. Results suggested that BN/SnO₂ composite possesses good capability for use in environmental as well as industrial applications.

氮化硼（BN）由于其非凡的光学，化学和机械性能而近来得到了研究。BN对它的晶体结构很敏感，晶格参数的微小变化会极大地改变其性能。目前的研究涉及BN基复合材料的合成，表征以及光催化应用。当将BN与具有四方晶体结构的SnO ₂混合时，发生离解成较小的片，并且材料取向为（102）面。附着在BN片两面的SnO ₂颗粒具有较高的表面积，使该材料适用于催化过程。大量活性位点的存在导致BN / SnO _2中形成羟基自由基有助于降解有机和无色污染物的复合材料，例如，甲基橙染料在7分钟内降解至约92％，而水杨酸在40分钟内降解至约82％。结果表明，BN / SnO ₂复合材料具有良好的环境和工业应用能力。
