本站小编 Free考研考试/2024-01-28


纳米碳材料具有导电性高、比表面积大、化学成分和结构可调、资源丰富、可持续性强等特点,在先进催化电极材料,染料光降解剂、染料吸附剂及荧光传感器等方面具有潜在的应用价值。
理学院稀土化学及应用辽宁省重点实验室李文泽教授团队带领刘禹博士,张潇飒博士及栾健博士近年来纳米碳材料方面取得以下进展:
一、纳米碳负载催化剂
通过浸渍法将离子液体(IL)负载到乙炔黑(AB)载体上制备IL@AB催化剂,并与电解液中的表面活性剂分子协同作用调节电极-电解质界面结构提升催化剂性能。研究发现,IL@AB催化剂使电合成H2O2的选择性成倍增加,并且在电解液中加入阳离子表面活性剂,可以使固-液界面上的过氧化物阴离子更容易解吸,从而使H2O2的选择性进一步提高(高选择性可以长时间保持稳定)。(该工作发表在Chemical Engineering Journal, 2022, 444, 136665,图1)

此外,课题组利用电化学沉积法成功制备Cu/CP催化材料,通过对沉积条件的控制能够实现对负载Cu物种化学结构和形貌的调控。使其中晶枝状纳米铜具有晶粒尺寸小、电化学比表面积大、阻抗小的优点。这类Cu/CP催化剂在电化学辅助CO2和氧化苯乙烯SO的环加成反应中表现出较高的活性可以高效催化SO和CO2的环加成反应制备碳酸苯乙烯脂(SC)。该反应体系的建立为CO2资源的高效利用以及电化学合成精细化学品SC提供了一条绿色、可持续的新途径。(该工作发表在(Chem. Eur. J, 2022, 28, e202200622,图2)

二、纳米碳染料光降解剂
通过直接碳化以及纳米碳和杂原子掺杂策略合成碳纳米结构,该类纳米碳材料可以快速的光催化降解去除水中的染料,该研究为大规模水处理提供了一种优良的高性价比碳纳米材料。(Dalton Trans, 2021, 50, 18173;Journal of Environmental Chemical Engineering, 2022, 10, 108215;Dalton Trans, 2022, 51, 17319 图3; Journal of Solid State Chemistry, 2021, 303, 122506)

三、纳米碳染料吸附剂
本研究采用热解法将配合物作为前驱体直接碳化,或者将杂原子从MOF的催化剂前驱体中加入到层状碳纳米结构中可以改善吸附性能。研究成果揭示了具有高比表面积和热稳定性的碳基纳米材料对有机染料选择性吸附,相关工作发表在( Dalton Trans, 2021, 50, 10549 (图4)、 Journal of Inorganic and Organometallic Polymers and Materials, 2022, 32, 700、 RSC Adv, 2021, 11, 33102和Journal of Solid State Chemistry, 2021, 304, 122589 )

四、纳米碳荧光传感器
本研究制备并验证了碳基纳米材料在荧光传感方面的优秀性能(Journal of Environmental Chemical Engineering, 2022, 10, 108215图5),揭示热解后纳米碳材料具有发光特性,可作为废水分析物检测的可选功能材料。
