摘　　要：硫化锌、氧化锌材料是常见的Ⅱ-Ⅵ族宽禁带半导体材料,其较大的禁带宽度和丰富的发光色彩,令其在光催化、化学电池、量子点材料等领域具有广泛应用潜力。然而,本征态的硫化锌与氧化锌材料具有激发态不稳定、光生电子与空穴易复合以及可见光利用不足等自身缺陷,极大地限制了其实际应用。硫化锌与氧化锌的制备方法多种多样,有液相法、气相法、固相法、生物法等,不同的实验条件(如温度、浓度和前驱体种类)会导致不同的微观形貌,从而带来不同的性质;除此以外,通过掺杂、复合等改性手段也是改良纳米材料性能的不二选择。近年来,研究者们已经采用了诸如元素掺杂、表面形貌调控或二维材料复合等改性方法提升硫化锌、氧化锌的反应活性。理论计算化学是随计算机技术与量子力学进步而新兴的学科,相比于实验化学,其在研究物质结构、预测化合物的反应活性、研究反应的微观本质过程等问题中,具有独特的优势。目前,硫化锌与氧化锌的本征态计算已很成熟,对于元素掺杂以及复合体系的计算也很火热,但由于选用近似方法的不同,得到的计算结果与实际实验会有差异,寻求更为精确的近似方法是亟待解决的问题。本文综述了硫化锌、氧化锌及其复合材料的制备方法、理论研究进展,从光催化、电池、量子点和医疗领域介绍了其应用现状,最后对其未来的发展方向进行了展望。Zinc sulfide and zinc oxide materials are common group II-VI wide band-gap semiconductor materials.Their large band-gap width and abundant luminescent colors make it possible for them to have wide application potential in photocatalysis,chemical batteries,quantum dot materials and other fields.However,the intrinsic state of zinc sulfide and zinc oxide materials have their own defects,such as the unstable excited state,easily recombination of photogenerated electrons and holes,and insufficient utilization of visible light,which greatly limit their practical applications.The preparation methods of zinc sulfide and zinc oxide are various,including liquid phase method,gas phase method,solid phase method,biological method,etc.Different experimental conditions(such as temperature,concentration and type of precursor)will lead to different micro-morphologies,resulting in different properties.Besides,modification methods such as doping and compounding are also good choices to improve the performance of nanomaterials.In recent years,researchers have adopted modification methods such as element doping,surface morphology control or two-dimensional material composite to enhance the reaction activity of zinc sulfide and zinc oxide.Theoretical computational chemistry is an emerging discipline with the progress of computer technology and quantum mechanics.Compared with experimental chemistry,it has unique advantages in studying the structure of substances,predicting the reactivity of compounds,and studying the microscopic essential process of reactions.At present,the calculation of the eigenstates of zinc sulfide and zinc oxide is very mature,and the calculation of element doping and composite system is also hot.However,due to the difference of approximation methods,the calculated results will be different from the actual experiment,so it is urgent to seek more accurate approximation methods.The preparation methods and theoretical researches were summarized in this paper together with zinc sulfide,zinc oxide and their composites
