Description
技术领域
本发明属于化学催化技术领域。更具体地，涉及一种超薄纳米片状石墨相氮化碳的制备方法和应用，具体是指在光催化分解水产氢中的应用。
背景技术
当今社会面临的能源短缺问题，迫使人们不断开发新能源和新材料。其中，利用具有可见光活性的半导体光催化剂，将太阳能转化为化学能，特别是氢能，光催化分解水制氢被认为是解决日益增长的能源和环境问题的最有希望的解决方案之一。2009年，王等报道了一类新型半导体光催化剂—石墨相氮化碳(g-C3N4)，用于光催化分解水制氢，由此掀起了该类光催化剂研究的热潮。然而，通常方法制备的块状g-C3N4具有比表面积小、可见光吸收效率差、电荷复合速率高、电导率低等缺点，大大限制了其光催化产氢效率。
解决上述问题的方法之一是将块状g-C3N4进行剥离，得到片层状g-C3N4。目前，已经建立了几种剥离方法，包括热氧化剥离、超声辅助液体剥离、化学剥离等。然而，上述方法存在产率低、剥离效果差、制备条件苛刻(如需要使用强酸、氨气等条件)等问题。
因此，迫切需要开发新型、绿色、简便的方法，用来制备超薄纳米片状g-C3N4，以满足批量化放大生产的需求，并将其用作高效光催化剂分解水制氢。
发明内容
本发明要解决的技术问题是克服上述现有技术的缺陷和不足，提供一种三聚氰胺泡沫(MF)覆盖尿素的简便一步烧结法，用来合成超薄纳米片状石墨相氮化碳(g-C3N4)。
本发明的目的是提供一种超薄纳米片状石墨相氮化碳的制备方法。
本发明另一目的是提供所述方法制备得到的超薄纳米片状石墨相氮化碳。
本发明另一目的是提供所述超薄纳米片状石墨相氮化碳在光催化分解水产氢中的应用。
本发明上述目的通过以下技术方案实现：
一种超薄纳米片状石墨相氮化碳的制备方法，是在尿素上面覆盖一块三聚氰胺泡沫，加热反应即可制备得到超薄纳米片状石墨相氮化碳(CN-UMF)。
具体优选地，所述超薄纳米片状石墨相氮化碳的制备方法是：在反应容器(如坩埚)中加入尿素，然后在上面覆盖一块厨房用三聚氰胺泡沫，再盖上容器盖，置于马弗炉中，加热反应制备得到超薄纳米片状石墨相氮化碳(CN-UMF)。
其中，优选地，加热的条件为空气气氛下450～650℃加热2～5小时。
更优选地，加热的条件为550℃加热4小时。
另外，由上述方法制备得到的超薄纳米片状石墨相氮化碳，也应在本发明的保护范围之内。
所得纳米片状石墨相氮化碳(CN-UMF)具有更大的比表面积、可见光吸收和光催化产氢效率，因此，其在在光催化分解水产氢中的应用，以及在作为或制备光催化分解水产氢的催化剂方面的应用，也均应在本发明的保护范围之内。
本发明具有以下有益效果：
发明提供了一种三聚氰胺泡沫(MF)覆盖尿素的简便一步烧结法，成功地合成获得了超薄纳米片状石墨相氮化碳(g-C3N4)。该方法简单、方便，只需引入三聚氰胺泡沫覆盖即可，所得产品获得了更大的比表面积、可见光吸收和光催化产氢效率。
与没有MF覆盖条件下单纯尿素烧结制备的块状石墨相氮化碳(CN-U)相比，本发明方法所制备的纳米片状石墨相氮化碳(CN-UMF)的比表面积为150.3m2g-1，平均厚度约为4.5nm，能够用作光催化剂，在可见光波段的LED灯或氙灯照射下，高效光催化分解水制氢，最高产氢效率达到5498μmol g-1h-1。

具体实施方式
以下结合说明书附图和具体实施例来进一步说明本发明，但实施例并不对本发明做任何形式的限定。除非特别说明，本发明采用的试剂、方法和设备为本技术领域常规试剂、方法和设备。
除非特别说明，以下实施例所用试剂和材料均为市购。
实施例1超薄纳米片状石墨相氮化碳(CN-UMF)的制备
1、制备方法：
CN-UMF的制备方法如图1所示。在坩埚中加入20克尿素，然后在上面覆盖一块厨房用三聚氰胺泡沫(MF，45×60×30立方毫米)，置于马弗炉中，空气气氛下550℃加热4小时，即可得到CN-UMF(0.53克)。
2、另外作为对照，在无MF覆盖条件下的单纯尿素烧结得到样品CN-U(0.37克)。
实施例2产品表征
1、表征方法
利用Rigaku Smartlab衍射仪进行粉末衍射表征(40kV，40mA， )。利用Nicolet/Nexus-670光谱仪进行傅立叶变换红外光谱测试(400～4000cm-1)。利用Quantachrome Autosorb-iQ2-MP气体吸附分析仪，在77K下对样品进行BET比表面积和孔体积的表征。利用岛津SPM-9500J3，获取原子力显微镜(AFM)图像。利用SU8010扫描电子显微镜(SEM)观察样品的形貌。利用JEM-2010HR，在200kV的加速电压下获得透射电子显微镜(TEM)图像。
2、结果
(1)CN-UMF和CN-U样品的X射线粉末衍射(XRPD)如图2所示。两个样品均表现出两个不同的衍射峰，在27.6°附近的(002)峰较强，是石墨结构共轭芳香体系的特征层间衍射。在约13°附近的(100)小峰可归属于三-s-三氮杂嗪的平面内重复单元。与CN-U相比，CN-UMF的(002)峰从27.6°略微移动到27.5°，对应于g-C3N4层间距的略微增大。
(2)CN-UMF和CN-U的红外吸收谱如图3所示。1200～1600cm-1的吸收带对应于芳香杂环单元的C-N伸缩峰。807cm-1处的峰归属于三嗪单元。3000～3500cm-1的宽带吸收对应于未聚合的末端氨基(-NH2或＝NH基团)。
(3)用N2吸附-脱附测试获得CN-UMF和CN-U的孔结构和BET表面积。图4显示了所获得的吸附等温线和BJH孔径分布曲线。计算得到CN-UMF的比表面积为150.3m2g-1，远远高于CN-U(37.5m2g-1)。
(4)图5显示了CN-UMF和CN-U的SEM和TEM图像。可以看到，CN-U主要由块状团聚体组成。CN-UMF则由许多具有折叠形状和不规则边缘的超薄纳米片组成。
(5)图6显示了CNU-MF的原子力显微镜(AFM)图像。通过AFM厚度分析表明，纳米片的平均厚度约为4.5nm，相当于约12～13个原子层。
实施例3光催化测试
1、测试方法
在可见光照射下，对CN-UMF的光催化产氢活性进行了评价。可见光由平均强度为10mW cm-2的白光LED灯，或配有紫外线截止滤光片(波长＞420nm)的150瓦氙灯提供。将10毫克的光催化剂粉末分散在含有三乙醇胺牺牲剂(体积比10％)的水溶液(10毫升)中。用H2PtCl6原位光沉积法，在光催化剂表面负载重量比3％的Pt。将N2通入反应液中30分钟以除去空气，然后用橡胶隔膜密封。在连续的磁力搅拌下，进行光催化测试，反应过程中利用冷却空气流使其温度保持在25℃。利用配备有热导型(TCD)检测器和TDX-01柱的Fuli GC-9790气相色谱仪进行产氢量测试。
2、结果
在白光LED灯照射下，以Pt为助催化剂，三乙醇胺为电子牺牲剂，对样品进行光催化分解水制氢测试。
结果如图7所示，CNU-MF的产氢速率达到2040μmol g-1h-1，约为CN-U(303μmol g- 1h-1)的6.7倍。当使用具有截止滤光片(波长＞420nm或AM1.5G)的氙灯作为光源时，CNU-MF的产氢速率分别达到2782μmol g-1h-1和5498μmol g-1h-1。
在相同的反应条件下测试了四个循环，验证了CN-UMF的催化稳定性。在可见光连续照射下，16小时没有明显的失活。CNU-MF的产氢波长依赖性与其光吸收一致，表明析氢反应确实是由光诱导产生的。
上述实施例为本发明较佳的实施方式，但本发明的实施方式并不受上述实施例的限制，其他的任何未背离本发明的精神实质与原理下所作的改变、修饰、替代、组合、简化，均应为等效的置换方式，都包含在本发明的保护范围之内。
