Industrial effluents contain various toxic substances and the removal or conversion of these substances to non-toxic products is highly crucial. The work emphasized on the green synthesis of silver nanoparticles with furfural, a promising derivative of lignocellulosic biomass (FAgNPs) for exploring its catalytic efficiency in the photocatalytic reduction of hexavalent chromium [Cr(VI)]. A peak at 410 nm was obtained with a molar ratio of 1:1 (silver nitrate to furfural) at pH 9. The effect of initial concentration of Cr(VI), pH, catalyst dosage, time on reduction of Cr(VI) has been investigated. The photocatalytic efficiency of 1 g/L FAgNPs was studied and 9% to 88% Cr(VI) reduction was observed with decreasing Cr(VI) concentration at pH 2. Under UV illumination, electron–hole pairs generated in FAgNPs resulted in the migration of photo generated electrons for the reduction process which is highly pH dependent. The photocatalytic reduction process can be explained by Langmuir–Hinshelwood model and fits into pseudo-first order kinetics. HaCaT cells exposed to Cr(VI) after being treated with FAgNPs for various time period exhibited an increase in cell viability with time which further substantiated its efficiency. Therefore, the study was an attempt to prepare a nanomaterial by a simple, facile method for the photocatalytic reduction of hexavalent chromium with a focus on environmental remediation.

工业废水中含有各种有毒物质，这些物质的去除或转化为无毒产品至关重要。这项工作着重于用糠醛绿色合成银纳米颗粒，糠醛是一种有前景的木质纤维素生物质（FAgNPs）衍生物，用于探索其在光催化还原六价铬[Cr（VI）]中的催化效率。在pH 9处，摩尔比为1：1（硝酸银与糠醛）时，在410 nm处出现一个峰。Cr（VI）的初始浓度，pH，催化剂用量，时间对Cr（VI）还原的影响为被调查。研究了1 g / L FAgNPs的光催化效率，并发现在pH 2下，随着Cr（VI）浓度的降低，Cr（VI）还原了9％至88％。FAgNPs中产生的电子-空穴对导致光生电子迁移到高度依赖pH的还原过程。可以用Langmuir-Hinshelwood模型解释光催化还原过程，并将其拟合为拟一级动力学。在用FAgNPs处理了不同时间段后暴露于Cr（VI）的HaCaT细胞随着时间的推移显示出细胞活力的增加，这进一步证实了其效率。因此，该研究是通过简单，简便的方法来制备六价铬的光催化还原，重点是环境修复的纳米材料的尝试。在用FAgNPs处理了不同时间段后暴露于Cr（VI）的HaCaT细胞随着时间的推移显示出细胞活力的增加，这进一步证实了其效率。因此，该研究是通过简单，简便的方法来制备六价铬的光催化还原纳米材料的尝试，其重点是环境修复。在用FAgNPs处理了不同时间段后暴露于Cr（VI）的HaCaT细胞随着时间的推移显示出细胞活力的增加，这进一步证实了其效率。因此，该研究是通过简单，简便的方法来制备六价铬的光催化还原，重点是环境修复的纳米材料的尝试。
