Neodymium Vanadate (NdVO) nanostructures were successfully synthesized via a modified solid state method in the presence of ligand. These nanoparticles were further used as a photocatalyst. Primarily the best structural formations and smallest crystallite sizes of the systems were identified and optimized by changing the calcination time, calcination temperature and molar ratio of the ligand. The cationic (Methyl Violet (MV)), and anionic (Eosin Y (EY) and Eriochrome Black T (EBT)) dyes were used as a model to evaluate the photoactivity under UV-Vis irradiation. Several operational factors were examined to improve the photocatalytic efficiency include type of dye, type of light source, pH and dye concentration. As a result, the best efficiency in 5 ppm Eriochorome Black T at pH = 11 was achieved in the presence of 0.05 g NdVO nanocatalysts.
钕钒酸镧（NdVO）纳米结构通过在配体存在下的改良固相法成功合成。这些纳米粒子进一步被用作光催化剂。首先通过改变煅烧时间、煅烧温度和配体的摩尔比来确定和优化体系的最佳结构形态和最小晶粒尺寸。阳离子（甲基紫（MV））和阴离子（曙红 Y（EY）和铬黑 T（EBT））染料被用作模型，在 UV-Vis 照射下评估光活性。研究了几种操作因素来提高光催化效率，包括染料类型、光源类型、pH 值和染料浓度。结果，在 0.05g NdVO 纳米催化剂存在下，在 pH=11 时，5ppm 铬黑 T 的去除效率最高。
