Tin chalcogenides are important semiconducting materials due to their non-toxic nature, cost effectiveness and layered structure. In this study, a facile synthetic route has been employed for the synthesis of a bis(selenobenzoato)dibutyltin(IV) complex, and used along with the bis(thiobenzoato)dibutyltin(IV) complex, as single source precursors, to prepare binary tin chalcogenides and their solid solution
硫族锡化物由于其无毒性质,成本效益和层状结构而成为重要的半导体材料。在这项研究中,一个浅显的合成路线已经用于双(selenobenzoato)二丁基锡(合成IV)配合物,并与双一起使用(thiobenzoato)二丁基锡(IV)配合物,作为单一来源前体,以制备二元锡硫属化物及其固溶体(SnS 1- x Se x)在整个范围内。固溶体的合成通过胶体和熔融方法进行。从这两种途径获得的固溶体的比较分析表明,胶体方法提供了对组成的优异控制。UV-Vis-NIR分析显示,当从SnS迁移到SnSe时,带隙逐渐变化。

of different inert additives on the mechanochemicalsynthesis of SnS was studied. A transition from explosive to nonexplosive mechanochemical reaction was observed. It was shown that this change takes place only when a critical volume xc is occupied by inert material. The critical volume for a transition from an explosive to nonexplosive mechanochemicalsynthesis were determined for the chalcogenides
Combustion synthesis is a novel technique that utilizes the exothermic heat of a chemical reaction to maintain the reaction and to rapidly prepare materials. But, hitherto, none of unified criterion for the validation of combustion synthesis has been proposed. Herein, we proposed the conditions need to be met. In terms of kinetics, at the adiabatic temperature (Tad), the diffusion distance of atoms
燃烧合成是一种利用化学反应的放热来维持反应并快速制备材料的新技术。但是,迄今为止,尚未提出用于验证燃烧合成的统一标准。在此,我们提出了需要满足的条件。就动力学而言,在绝热温度(T ad)下,原子的扩散距离(升Ť广告)在0.1 s内应大于反应物的粒径(d), 那是, 升Ť广告≥d。对于满足T ad / T m,L的系统≥1(其中T m,L是反应物的低熔点成分的熔点),液相的存在将原子的扩散距离从纳米显着增加到数十微米,从而成为标准升Ť广告≥d简化为T ad / T m,L≥在大多数情况下为1。在热力学方面,系统需要确保反应成分处于激活状态,即T ad / T m,H ≥0.7,其中T m,H是高熔点组分的熔点。本研究提出的SHS反应标准进一步提高了对SHS反应的理论理解,并为探索二元和多组分化合物的超快合成提供了指导。
