在这项研究中，TiO 2纳米颗粒（平均粒径16 nm）成功地在熔盐相中产生，并显示出显着提高比热容的二元低共熔混合物的钠和钾硝酸盐（60/40）在390 °C下5.4%和7.5%在445 °C的3.0重量%的前体使用。本研究的目的是开发一种具有成本效益的替代生产方法，该方法具有潜在的可扩展性，因为目前使用的技术在经济上不适用于大批量生产。提高熔融盐的比热容将促进通过聚光太阳能发电厂进行电力生产的更具竞争力的定价。在这里，将简单的前体（TiOSO 4）添加到硝酸钾和硝酸钠的二元低共熔混合物中，加热到450 °C，并冷却以见证纳米颗粒的产生。
In this study, TiO2 nanoparticles (average particle size 16 nm) were successfully produced in molten salt phase and were showed to significantly enhance the specific heat capacity of a binary eutectic mixture of sodium and potassium nitrate (60/40) by 5.4 % at 390 °C and 7.5 % at 445 °C for 3.0 wt% of precursors used. The objective of this research was to develop a cost-effective alternate method of production which is potentially scalable, as current techniques utilized are not economically viable for large quantities. Enhancing the specific heat capacity of molten salt would promote more competitive pricing for electricity production by concentrating solar power plant. Here, a simple precursor (TiOSO4) was added to a binary eutectic mixture of potassium and sodium nitrate, heated to 450 °C, and cooled to witness the production of nanoparticles.
