Manganese doped zinc oxide (MZ) nanocomposites was uniquely synthesized using co-precipitation method. The photocatalytic activity of the synthesized MZ nanocomposites was studied under ultraviolet light irradiation by the photodegradation of malachite green (MG), a toxic organic dye. MZ3 (1:25) nanocomposite This show the best photocatalytic activity among the different molar ratios of Mn/Zn by studying their spectroscopic behavior. The Langmuir-Hinshelwood model was utilized to calculate the reaction rate of such degradation which showed the highest degradation activity for MZ3 having reaction rate as 0.0145 min⁻¹. This may be because of its high surface area (9.8 m²/g) obtained using Brunauer-Emmett-Teller (BET) method.

采用共沉淀法独特地合成了锰掺杂的氧化锌（MZ）纳米复合材料。通过对有毒有机染料孔雀石绿（MG）的光降解，研究了合成的MZ纳米复合材料的光催化活性。MZ3（1:25）纳米复合材料通过研究其Mn / Zn的光谱行为，可显示出最佳的光催化活性。利用Langmuir-Hinshelwood模型来计算这种降解的反应速率，其对于反应速率为0.0145min ^-1的MZ3表现出最高的降解活性。这可能是由于使用Brunauer-Emmett-Teller（BET）方法获得的高表面积（9.8 m ² / g）。
