Abstract

The research focuses on the innovative use of graphite-like carbon nitride (gC3N4) catalysts along with supercritical carbon dioxide (scCO2) for the green synthesis of valuable organic compounds. Having explored different synthetic routes for gC3N4 and the obtained samples efficiency in the photocatalytic oxidation of benzyl alcohol with molecular oxygen in scCO2, we identified the most effective catalyst bearing ether linkers between layers of a graphite-like structure. This catalyst facilitates the production of benzaldehyde and benzoic acid derivatives, highlighting the potential for sustainable industrial applications. The study's emphasis on a metal-free catalyst and a zero-waste process underlines its contribution to environmentally friendly chemical practices. The proposed approach offers a more sustainable and efficient alternative to traditional processes in small-scale chemical production.

石墨氮化碳(gC3N4)与超临界二氧化碳的结合用于苯基醇的绿色光氧化
该研究的重点是创新地使用石墨样氮化碳(gC3N4)催化剂和超临界二氧化碳(scCO2)来绿色合成有价值的有机化合物。在探索了gC3N4的不同合成路线以及获得的样品在scCO2中与分子氧光催化氧化苯甲醇的效率后,我们确定了在石墨状结构层之间携带醚连接剂的最有效催化剂。这种催化剂有利于苯甲醛和苯甲酸衍生物的生产,突出了可持续工业应用的潜力。这项研究强调了一种无金属催化剂和零废物过程,强调了它对环境友好型化学实践的贡献。拟议的方法为小规模化学生产中的传统工艺提供了一种更可持续和更有效的替代方法。
