摘要将石墨氮化碳 (g-C3N4) 剥离成超薄纳米片通常是其透视应用的第一步。与传统耗时的超声处理方法相比，需要一种快速且高产的合成 g-C3N4 纳米片的方法。在这项研究中，我们开发了一种高效且通用的策略，通过将发泡剂插入与微波消解方法相结合，将块状 g-C3N4 剥离成二维超薄纳米片。所提出的方法显着减少了剥离时间，并可进一步用于生产金属氧化物 (MOY) 或金属硫化物 (MSY) 装饰的 g-C3N4 纳米片。形成的超细 ZnO 纳米晶装饰 g-C3N4 纳米片 (ZnO/g-C3N4) 表现出优异的溶解性和双发射光学性能，可用作金属离子传感的荧光探针。得到的 CdS/g-C3N4 装饰纳米片表现出高效的光催化性能，在光降解应用中具有巨大的潜力。该协议可以作为合成 g-C3N4 纳米片的通用策略，并且在制备许多功能性混合纳米片以用于传感探针、太阳能电池、光电器件和水处理的未来应用方面具有吸引力。

Filling foaming agent into stacked layers: Rapid synthesis of graphitic carbon nitride nanosheets decorated with ultrafined MX Y ( X  =  O, S ) nanoparticles for enhanced photoresponsive abilities

Abstract Exfoliation of graphitic carbon nitride (g-C3N4) into ultrathin nanosheets is usually the first step for its perspective applications. In contrast to the traditional time-consuming ultrasonication approach, a rapid and high-yield method to synthesis g-C3N4 nanosheets is desirable. In this study, we develop an efficiency and versatile strategy to exfoliate bulk g-C3N4 into 2D ultrathin nanosheets by combining foaming agent inserting with microwave digestion method. The proposed method significantly reduces the exfoliation time and can be further utilized to produce metal oxides (MOY) or metal sulfide (MSY) decorated g-C3N4 nanosheets. The as-formed ultrafined ZnO nanocrystals decorated g-C3N4 nanosheets (ZnO/g-C3N4) exhibit excellent solubility and dual-emission optical property, which can be served as fluorescence probes for metal ion sensing. The resulted CdS/g-C3N4 decorated nanosheets demonstrate efficient photocatalytic properties, having great potentials in photodegradation application. This protocol can be a general strategy for the synthesis of g-C3N4 nanosheets as well as attractive in preparing a lot of functional hybrid nanosheets for future applications in sensing probes, solar cells, photoelectrical devices and water treatment.
