This investigation reports on the efficacy of a photoelectrocatalysis (PEC) system enhanced by nitrogen-doped TiO2 nanocrystal-modified nanotube array (N-TiO2 NCs/TNTAs) anode paired with graphene oxide/activated carbon (GO/AC) photocathode for diclofenac removal from effluent. The FE-SEM and EDX analyses validated elemental composition anode—27.56% C, 30.81% N, 6.03% O, 26.49% Ti. XRD results confirmed anatase phase nitrogen integration, essential photocatalytic activity enhancement. Quantum chemical simulations provided comprehensive understanding red-shifted absorption bands in N-TiO2, UV-vis DRS demonstrated red-shift to visible spectrum, indicating improved light utilization. PEC configuration achieved photocurrent density 9.8 mA/dm2, significantly higher than unmodified solely counterparts at 4.8 mA/dm2 6.1 respectively. Notably, this reduced concentrations 58% within 75 min, outperforming standard setups. These findings underscore potential N-TiO2 NCs/TNTAs-AC-GO/PTFE composite material advanced environmental photoelectrocatalytic applications.

Wastewater treatment using biotechnological approaches provides environmentally friendly ways of treating industrial effluents for pollution control and resource realization. The capability microbial consortia, enzymatic machinery genetically modified microorganisms to metabolize high molecular weight compounds including heavy metals, synthetic chemicals toxic organic substrates outlines this approach. However, there are issues with the concept being implemented such as operation problems, problems scalability, question exactly how species environment. new technologies include metagenomics, biology, hybrid systems bio physical that generally improve efficacy pollutant removal.
