Reactive Electrochemical Membrane (REM) prepared from carbothermal reduction of TiO₂ is used for the mineralization of biorefractory pollutants during filtration operation. The mixture of Ti₄O₇ and Ti₅O₉ Magnéli phases ensures the high reactivity of the membrane for organic compound oxidation through ^•OH mediated oxidation and direct electron transfer. In cross-flow filtration mode, convection-enhanced mass transport of pollutants can be achieved from the high membrane permeability (3,300 LMH bar^-1). Mineralization efficiency of oxalic acid, paracetamol and phenol was assessed as regards to current density, transmembrane pressure and feed concentration. Unprecedented high removal rates of total organic carbon and mineralization current efficiency were achieved after a single passage through the REM, e.g. 47 g m^-2 h^-1 – 72% and 6.7 g m^-2 h^-1 – 47% for oxalic acid and paracetamol at 15 mA cm^-2, respectively. However, two mechanisms have to be considered for optimization of the process. When the TOC flux is too high with respect to the current density, aromatic compounds polymerize in the REM layer where only direct electron transfer occurs. This phenomenon decreases the oxidation efficiency and/or increases REM fouling. Besides, O₂ bubbles sweeping at high permeate flux promotes O₂ gas generation, with adverse effect on oxidation efficiency.

由TiO _2的碳热还原制备的反应性电化学膜（REM）用于过滤操作期间矿化难熔污染物。的Ti的混合物₄ ö ₇和Ti _5个ö ₉马格涅利相确保通过该膜对有机化合物氧化的高反应性^• OH介导的氧化和直接电子转移。在错流过滤模式下，可通过高膜渗透性（3,300 LMH bar ^-1）实现对流增强的污染物的质量传输）。就电流密度，跨膜压力和进料浓度评估了草酸，扑热息痛和苯酚的矿化效率。单次通过REM后，实现了前所未有的高总有机碳去除率和矿化电流效率，例如，草酸和扑热息痛在47 gm ^-2 h ^-1 – 72％和6.7 gm ^-2 h ^-1 – 47％ 15 mA厘米^-2， 分别。但是，必须考虑两种机制来优化过程。当TOC通量相对于电流密度太高时，芳族化合物在仅直接发生电子转移的REM层中聚合。这种现象降低了氧化效率和/或增加了REM结垢。此外，以高渗透通量吹扫的O ₂气泡促进了O ₂气体的产生，对氧化效率产生不利影响。
