Abstract

The advent of nanotechnology has helped in several invention in science & technology. Contamination of surface water, ground and soil by various industrial dyes causes several ecological problems. Zinc oxide nanoparticles as photocatalysts and semiconductor materials show unique physical properties at the nanoscale and can be used to solve these problems to some extent. In this paper, we synthesized ZnO NPs and calcium-coated ZnO nanoparticles using extract of beetroot and then, for industrial point of view, we studied the photocatalytic degradation of methylene blue and rhodamine B using sun as a natural light source (sunlight). We have synthesized calcium-coated ZnO nanocomposites with 20–50 nm particle size. Synthesized nanomaterials were characterized by using the different physio-chemical techniques such as - FT-IR, XRD, TEM, SEM, EDX and UV-spectrophotometer do their photocatalytic degradation.

甜菜根提取物生物合成包钙氧化锌纳米粒子及其对亚甲基蓝和罗丹明B的光降解研究

纳米技术的出现有助于科学领域的几项发明；技术各种工业染料对地表水、地面和土壤的污染造成了一些生态问题。氧化锌纳米粒子作为光催化剂和半导体材料，在纳米尺度上表现出独特的物理性质，可以在一定程度上解决这些问题。在本文中，我们使用甜菜根提取物合成了ZnO纳米颗粒和钙包覆的ZnO纳米颗粒，然后，从工业角度出发，我们研究了以太阳光为自然光源（阳光）光催化降解亚甲基蓝和罗丹明B。我们合成了粒径为20–50 nm的钙涂层ZnO纳米复合材料。利用FT-IR、XRD、TEM、SEM、EDX和UV分光光度计等理化技术对合成的纳米材料进行了表征，对其进行了光催化降解。
