Novel inorganic antibacterial agent (AgLaMo2O8) and preparation method thereof
The invention relates to the field of antibacterial materials, in particular to a novel inorganic antibacterial agent (AgLaMo2O8) and a preparation method thereof. A sol-gel self-combustion method is adopted, silver nitrate, lanthanum nitrate and (NH4) 6Mo7O24 are used as raw materials, citric acid is used as a complexing agent, ammonia water is used as a pH regulator, and silver lanthanum molybdate (AgLaMo2O8) superfine powder with different particle sizes is synthesized at low temperature in one step by controlling the dosage of the citric acid and the self-combustion ignition temperature and time. The invention provides a method for low-temperature one-step synthesis of tetragonal system AgLaMo2O8 ultrafine powder, which is applied to the antibacterial field for the first time. The method is short in reaction time, simple in process, convenient to operate, high in purity and yield, low in cost and easy for large-scale production; the obtained AgLaMo2O8 ultrafine powder has better high-temperature stability and antibacterial performance, the high-temperature application advantage is more obvious, and the application field is wider.
本发明涉及抗菌材料领域，尤其涉及一种新型无机抗菌剂(AgLaMo2O8)及其制备方法。本发明采用溶胶‑凝胶自燃烧法，以硝酸银、硝酸镧和(NH4)6Mo7O24为原料，柠檬酸为络合剂，氨水为pH调节剂，通过控制柠檬酸用量及自燃烧引燃温度和时间，低温一步合成不同粒径的钼酸镧银(AgLaMo2O8)超细粉体。本发明提供了一种低温一步合成正方晶系AgLaMo2O8超细粉体的方法并首次应用于抗菌领域，该方法反应时间短，工艺简单，操作方便，纯度产率高，成本低，易于规模化生产；所得AgLaMo2O8超细粉体具有更好的高温稳定性及抑菌性能，高温应用优势更加明显，应用领域更为广泛。
