Photocatalysts composed of ZnSe nanorods were prepared by using a glancing angle deposition technique facilitated electron beam evaporation equipment. To enhance the photocatalytic efficiency ZnSe, vulcanization process was introduced. The impact various parameters, including curing temperature, duration, and nanorod length, on performance systematically examined. Comprehensive analysis X-ray diffraction, scanning microscopy, photocurrent density–potential curves identified optimal conditions at 300 °C for 45 min 170 nm nanorods. Under these conditions, reached 44.53 μA/cm2, approximately 7-fold greater than that untreated Furthermore, degradation Rhodamine B increased 50%. Detailed mechanism revealed sulfurization not only enhances light absorption but also facilitates separation photogenerated carriers through formation ZnS.
