摘要:
以bulk类石墨相氮化碳为前驱体，氨水为溶剂，通过水热法制备了超薄氮化碳，并成功构建了五氯酚（PCP）高灵敏的电化学传感器。对碱源和剥离时间等制备条件进行了优化，结果表明：氮化碳在以弱碱氨水为溶剂时能成功地剥离，然而在有机弱碱为溶剂的情况下导致氮化碳大量溶解而未能成功剥离。另外，剥离时间对氮化碳的形貌和成分影响非常大。剥离6 h后得到管状形貌且有蜜勒胺生成的混合物。而剥离4 h则可得到纯的超薄氮化碳，其禁带宽度Eg为2.641 eV，价带EVB为1.774 V，所构建的超薄氮化碳电化学传感器的阻抗最小，用于环境激素PCP的检测，其线性范围为3.1×10-7~1.1×10-4 mol·L-1，检出限为100 nmol·L-1，建立了一种灵敏、快速简便的PCP电化学检测新方法。
Abstract:
The ultra-thin carbon nitride was prepared by a hydrothermal method under alkaline conditions with bulk graphitic carbon nitride as precursors，ammonia water as an exfoliation solvent. A highly sensitive electrochemical sensor of pentachlorophenol （PCP） was successfully constructed with the ultra-thin carbon nitride. The preparation conditions such as the alkali source and exfoliation time were optimized. The result shows that carbon nitride can be successfully exfoliated in a weak alkaline ammonia. However，it is not easily exfoliated in a weak organic alkali because a large amount of carbon nitride is dissolved. Moreover，the exfoliation time of ammonia water has a great influence on the morphology and composition of carbon nitride. After 6 hours of exfoliation，a mixture including melem products is obtained，and the morphology is tubular. The ultra-thin carbon nitride can be obtained after exfoliation for 4 h. Its band gap energy Eg is 2.614 eV，and the valence band energy EVB is 1.774 V. The electrochemical sensor constructed by ultra-thin carbon nitride has the smallest impedance， and it is used for the detection of environmental hormone PCP. The linearity range is 3.1×10-7- 1.1×10-4 mol·L-1，and the detection limit is 100 nmol·L-1. A sensitive，fast and simple new method for electrochemical detection of PCP has been established.
