Datasets on growth kinetics evaluation of hydrothermally synthesised Co2(OH)3Cl nanoparticles for application in solar thermal heat transfer fluids

2021FEBEREC-STD-056X-ray diffraction (XRD) and transmission electron microscopy (TEM) data obtained from the growth of cobalt hydroxychloride (Co2(OH)3Cl) nanopowders over time in the presence of 70% propanol and water, respectively are provided. Furthermore, data obtained from the XRD, TEM and attenuated total reflectance-Fourier transformed infrared (ATR-FTIR) analyses of Co2(OH)3Cl nanopowders synthesised via hydrothermal precipitation at varying propanol concentrations ranging from 0% to 100% are available. Data obtained from the Ultraviolet–visible–near–infrared (UV–VIS–NIR) spectroscopy, viscosity and thermal conductivity analyses of Co2(OH)3Cl-H2O nanofluids prepared via a two-step method are also provided. The prepared nanofluids were examined for thermal conductivity and viscosity, at temperatures ranging between 298 K and 318 K and 298 K to 308 K, respectively. Data obtained from the computational calculations based on Equilibrium Molecular Dynamics (EMD) simulations integrated with the Green-Kubo (EMD-GK) method for Co2(OH)3Cl-H2O nanofluids with very narrow particle sizes (< 10 nm) and different shapes (i.e., rhombus nanoplates and spherical) are also available.

本数据集提供了在70%丙醇和水存在下，随时间推移生长的氯化钴羟基氯化物（Co2(OH)3Cl）纳米粉末的X射线衍射（XRD）和透射电子显微镜（TEM）数据。此外，还包括了通过水热沉淀法在0%至100%不同丙醇浓度下合成的Co2(OH)3Cl纳米粉末的XRD、TEM和衰减全反射-傅里叶变换红外（ATR-FTIR）分析数据。同时，还提供了通过两步法制备的Co2(OH)3Cl-H2O纳米流体在紫外-可见-近红外（UV-VIS-NIR）光谱、粘度和热导率分析数据。所制备的纳米流体在298 K至318 K和298 K至308 K的温度范围内分别进行了热导率和粘度的测试。此外，还提供了基于平衡分子动力学（EMD）模拟与Green-Kubo（EMD-GK）方法相结合的计算数据，这些数据针对具有极窄粒径（< 10 nm）和不同形状（例如，菱形纳米片和球形）的Co2(OH)3Cl-H2O纳米流体。
