Green synthesis of nanoparticles can be beneficial due to their low toxicity, cost-effectiveness, and environment-friendliness. Its synthesis involves the use of eco-friendly and biodegradable materials such as plant extracts, natural products, and microorganisms to reduce the negative environmental impacts of traditional nanoparticle synthesis methods. Herein, Spinacia oleracea leaves are used as a boron source, and a visible light active photo-catalyst is produced. The effect of Co-Catalyst Boron in Graphitic carbon nitride based nanocomposites for methylene blue dye photo-degradation in water is examined. Titanium dioxide (TiO) was activated by changing the hydrogen potential value while utilizing a typical orange dye as a sensitizer. The graphitic carbon nitride/TiO nanocomposites were synthesized through a hydrothermal technique. To improve their performance, Boron used as a co-catalyst and B-doped g-CN/TiOnanocomposites prepared through wet chemical co-percipitate mathod. UV-visible spectroscopy, SEM and FTIR spectroscopy were used to analyze the photocatalyst and boron-doped composites in detail. The photocatalytic performance of pristine photocatalyst CNTx (x = 2%,4%,6%,8%) and B-doped CNTx composites were examined for Methylene Blue degradation in the presence of a light source. The spectroscopy analysis showed that B-doped g-CN/TiO -8% nano-composites performed better than all other synthesized pristine catalysts and composites in this research. This research has demonstrated that B-doped g-CN/TiO composites can provide an ideal solution for treating polluted water using visible light as a source to activate these photocatalysts.
纳米颗粒的绿色合成具有诸多益处，因为其毒性低、成本效益高且环境友好。其合成过程涉及使用生态友好型和可生物降解的材料，如植物提取物、天然产物和微生物，以减少传统纳米颗粒合成方法对环境的负面影响。在此，菠菜叶被用作硼源，并制备出一种可见光活性光催化剂。研究了基于石墨相氮化碳的纳米复合材料中助催化剂硼对水中亚甲基蓝染料光降解的影响。在使用典型橙色染料作为敏化剂时，通过改变氢电位值来激活二氧化钛（TiO）。通过水热技术合成了石墨相氮化碳/TiO纳米复合材料。为提高其性能，将硼用作助催化剂，并通过湿化学共沉淀法制备了硼掺杂的g-CN/TiO纳米复合材料。利用紫外可见光谱、扫描电子显微镜和傅里叶变换红外光谱对光催化剂和硼掺杂复合材料进行了详细分析。在有光源的情况下，研究了原始光催化剂CNTx（x = 2%、4%、6%、8%）和硼掺杂CNTx复合材料对亚甲基蓝降解的光催化性能。光谱分析表明，在本研究中，硼掺杂的g-CN/TiO - 8%纳米复合材料的性能优于所有其他合成的原始催化剂和复合材料。该研究表明，硼掺杂的g-CN/TiO复合材料可以为利用可见光作为光源激活这些光催化剂来处理污水提供理想的解决方案。
