In this era, nanotechnology is gaining enormous popularity due to its ability to reduce metals, metalloids and metal oxides into their nanosize, which essentially alter their physical, chemical, and optical properties. Zinc oxide nanoparticle is one of the most important semiconductor metal oxides with diverse applications in the field of material science. However, several factors, such as pH of the reaction mixture, calcination temperature, reaction time, stirring speed, nature of capping agents, and concentration of metal precursors, greatly affect the properties of the zinc oxide nanoparticles and their applications. This review focuses on the influence of the synthesis parameters on the morphology, mineralogical phase, textural properties, microstructures, and size of the zinc oxide nanoparticles. In addition, the review also examined the application of zinc oxides as nanoadsorbent for the removal of heavy metals from wastewater.

在这个时代，由于纳米技术能够将金属，准金属和金属氧化物还原为纳米尺寸，从而改变了它们的物理，化学和光学性质，因此纳米技术正获得极大的普及。氧化锌纳米颗粒是最重要的半导体金属氧化物之一，在材料科学领域具有多种应用。但是，反应混合物的pH，煅烧温度，反应时间，搅拌速度，封端剂的性质和金属前体的浓度等几个因素极大地影响了氧化锌纳米粒子的性质及其应用。这篇综述着重于合成参数对氧化锌纳米颗粒的形态，矿物相，组织性质，微观结构和尺寸的影响。此外，
