Membrane technology has been widely applied in water management systems for production, but is still hindered by fouling phenomena and low selectivity. Improving membrane performance through modification, such as the addition of photocatalytic materials, has been explored. In this research, La@TiO2 composite was incorporated into PVDF membranes for the treatment of produced water. Lanthanum doping on TiO2 effectively inhibits carrier recombination and enhances photocatalytic activity. According to the research results, adding the La@TiO2 composite to the membrane matrix increased the porosity value and membrane pore size. The PVDF-La@TiO2 1.5%wt membrane exhibited the highest flux values, specifically 20.59 L.m-2.h-1 and 40 L.m-2.h-1 in dark conditions and visible light irradiation. The rejection rates for COD, TDS, and ammonia were 69.89%, 57.77%, and 69.65%. The photocatalytic degradation effect of PVDF-La@TiO2 is proven by a significant difference in the filtration results under vis-light irradiation. The kinetics of COD removal are better described by a pseudo-first-order model. The degradation of PVDF-La@TiO2 1.5% pollutant demonstrated significant results, confirming its photocatalytic activity under irradiation. Overall, the membrane exhibited good performance and proved to be reusable after 6 hours of photofiltration. This research holds promise for enhancing the use of membrane photocatalytics in the treatment of produced water.

In this study, we synthesized a novel electrode for electrocatalytic adsorption by fabricating ACF‐TiO2 via the sol‐gel method and binding it with IrO2‐TaO2. The electrode's effectiveness in treating oilfield produced water (OPW) was evaluated using batch techniques. Comprehensive characterization, including scanning electron microscopy (SEM), energy‐dispersive spectrometry (EDS), Brunauer‐Emmett‐Teller (BET) analysis, and Fourier‐transform infrared (FTIR) spectroscopy, confirmed uniform TiO2 loading onto the ACF surface, preserving structural integrity. BET analysis indicated increased mesopore volume and enhanced organic adsorption capacity without compromising microporous structure. Additionally, FTIR analysis revealed the emergence of functional groups conducive to adsorption and catalytic reactions. Freundlich isotherms and pseudo‐first‐order kinetics best fit the adsorption data. Remarkably, even after five cycles, the electrode maintained high removal efficiencies for chemical oxygen demand (COD) and oil content at 91.35 % and 91.12 %, respectively. We further investigated the complex phenomena of material adsorption, electrochemical oxidation, and desorption during electrocatalytic adsorption, highlighting the importance of solid‐phase adsorption and liquid‐phase electrocatalytic oxidative decomposition in OPW treatment. Comparison with similar electrodes and DSA electrodes demonstrated the superior performance and practicality of the IrO2‐TaO2‐ACF(TiO2) electrode. Its cost‐effectiveness and regeneration method further enhance its applicability in real‐world scenarios, emphasizing its potential in water treatment.
