本文以硝基苯还原和亚甲基蓝降解为模型反应体系,以非金属氮掺杂石墨烯泡沫(NGF)作为三维结构式催化材料,研究了超重力环境对催化反应性能的影响。在超重力旋转圆管反应器内6484 g (g = 9.81 m·s–2)的超重力环境下,非金属催化硝基苯还原的表观速率常数是传统搅拌反应器内的6 倍。通过计算流体力学理论模拟,揭示了超重力旋转管式反应器内超重力水平较高,湍流动能比传统反应器内有显著提高,液固相表面更新速度快,提高了催化反应效率。X射线光电子能谱和拉曼光谱测试表明该催化材料组成和结构在超重力环境下的反应过程中保持稳定。在另一个模型反应体系中,非金属氮掺杂石墨烯泡沫催化亚甲基蓝降解的速率也随着超重力水平的增加而增大。这些结果表明了超重力强化非金属碳基催化材料催化还原反应的潜力。

PFRs were produced on biochar during Cr(VI) decontamination. PFRs formation on biochar was owing to the oxidization of phenolic-OH by Cr(VI). Appearance of excessive oxidant led to the consumption of PFRs on biochar. Biochar charred at high temperature possessed great performance to Cr(VI) removal.
