Investigating ecofriendly sustainable materials with excellent electrocatalytic activity is a pivotal approach for the analysis field. The present work reports on the preparation of novel three-dimensional (3D) cerium sulfide with gum arabic carbon flowers (Ce2S3/GACFs) via the hydrothermal method by using l-cysteine as a sulfur source, binding, and reducing agents. The intensive characterization techniques were utilized to corroborate the structural moiety, morphology, and size of Ce2S3/GACFs. The obtained 3D Ce2S3/GACF construction has excellent active sites, and hence it prevents the accumulation of carbon flowers. Furthermore, the obtained Ce2S3/GACF/glassy carbon electrode (GCE) could afford a very high electrocatalytic activity, possessing an exceedingly low detection limit of 32 nM, the high sensitivity of 2.65 μA μM-1 cm-2, good repeatability, and high stability for the detection of insecticide imidacloprid (IMC). The Ce2S3/GACF/GCE also provides a wide linear range of 0.05-1266 μM toward IMC detection. The excellent recovery results (90-99.3%) are achieved by using various spiked real food samples at Ce2S3/GACF/GCE. Confidently, this work gives up novel construction of 3D metal-carbon-based bioderived material for its catalytic application in the future.

单罐可持续合成Ce2S3 / Gum阿拉伯碳花纳米复合材料，用于检测杀虫剂吡虫啉。

研究具有优异电催化活性的环保可持续材料是分析领域的关键方法。本工作报道了使用l-半胱氨酸作为硫源，结合剂和还原剂通过水热法制备带有阿拉伯树胶碳花（Ce2S3 / GACFs）的新型三维（3D）硫化铈。密集的表征技术被用来证实Ce2S3 / GACFs的结构部分，形态和大小。所获得的3D Ce2S3 / GACF结构具有出色的活性中心，因此可以防止碳花的积累。此外，所获得的Ce2S3 / GACF /玻碳电极（GCE）可以提供非常高的电催化活性，具有32 nM的极低检测限，2.65μAμM-1cm-2的高灵敏度，检测杀虫剂吡虫啉（IMC）的重复性好，稳定性高。Ce2S3 / GACF / GCE还为IMC检测提供了0.05-1266μM的宽线性范围。通过在Ce2S3 / GACF / GCE上使用各种加标的真实食物样品，可获得极好的回收结果（90-99.3％）。充满信心的是，这项工作放弃了3D金属-碳基生物衍生材料的新颖结构，可用于未来的催化应用。
