Utilization of solar heat radiation into chemical energy is attributed to semiconductor photocatalyst under sunlight perspective considered as a reversing inspired approach that exacerbates the environmental problems. Recently, our group indicates graphitic carbon nitride (g-CN) by a progressive molecular aggregation co-polymerization process that propagated with a nanoscopic organic conjugated heterocyclic monomer to enhance its photocatalytic activity. This work aims to present a facile induced co-condensation technique and used 2, 6-Furandicarboxylic acid (FA) monomer as demonstrator within g-CN that boosting the photocatalytic properties under solar energy driven caused the reduction of water. The as-prepared samples were demonstrated for various characterizations along with computational evaluation of pure and doped g-CN. The result signifying the integration of organic FA monomer in the triazine core shell of g-CN restoring a substantial delocalization in its π-conjugated system. Meanwhile, after this alternation, an identifiable undulation occurred in the surface area, electronic structure, calculated band gap, chemical composition analysis of g-CN, and also improved its electronic generation process under the visible light radiance. Besides, this unrepeatable integrity of FA co-monomer with ing-CN matrix considerably enhanced the photocatalytic activity toward Godspeed and as such, the superior photocatalyst CN/FA12.0 stimulated a tremendous photocatalytic activity of water reduction with 10.6 enhanced catalytic performances as a contrast of pristine sample respectively.

用有机单体制备聚合物碳氮化物以有效地光催化制氢

将太阳热辐射转化为化学能的原因是在阳光透视下的半导体光催化剂被认为是一种可逆的启发方法,加剧了环境问题。最近,我们的研究小组通过逐步分子聚集共聚合过程显示了石墨碳氮化物(g-CN),该过程与纳米有机共轭杂环单体一起传播,以增强其光催化活性。这项工作的目的是提出一种简便的诱导共聚技术,并在g-CN中使用2,6-呋喃二甲酸(FA)单体作为演示剂,该单体在太阳能驱动下提高了光催化性能,从而减少了水含量。对制备的样品进行了各种表征,并对纯和掺杂的g-CN进行了计算评估。结果表明有机FA单体在g-CN的三嗪核壳中的整合恢复了其π共轭体系中的大量离域。同时,在这种交替之后,g-CN的表面积,电子结构,计算出的带隙,化学成分分析出现了可识别的起伏,并且在可见光辐射下也改善了其电子生成过程。此外,FA共聚单体与ing-CN基体的这种不可替代的完整性大大增强了对Godspeed的光催化活性,因此,它是优异的光催化剂CN / FA 电子结构,计算的带隙,g-CN的化学成分分析,以及在可见光辐射下改进了其电子生成过程。此外,FA共聚单体与ing-CN基体的这种不可替代的完整性大大增强了对Godspeed的光催化活性,因此,它是优异的光催化剂CN / FA 电子结构,计算的带隙,g-CN的化学成分分析,以及在可见光辐射下改进了其电子生成过程。此外,FA共聚单体与ing-CN基体的这种不可替代的完整性大大增强了对Godspeed的光催化活性,因此,它是优异的光催化剂CN / FA与原始样品相比,12.0刺激了巨大的水还原光催化活性,并增强了10.6的催化性能。
