Photocatalytic membrane reactors (PMRs) have been found to be very effective in the removal of organic pollutants (particularly recalcitrant compounds) from wastewater because they allow for mineralization innocuous by-products, thus achieving high-quality treated water. Owing high volumes water involved, sewage could reused if a efficient tertiary stage, like PMR, can foreseen. In this review, two main PMR configurations (photocatalytic membranes and slurry PMRs) were analyzed as requirements treatment considering six design operational parameters such plants: (i) continuous flow rate secondary stage; (ii) self-control photodegradation related chemical–physical parameters; (iii) ability handle variations concentration rate; (iv) control quality wastewater; (v) low plant footprint; (vi) easy maintenance. analysis, some characteristics photocatalysis (which involves three phases: solid (the photocatalyst), liquid wastewater), gas (oxygen or air)) those (they produced using different materials configurations, processes (pressure-driven not pressure-driven), etc.) considered. The obtained results show that PMRs seem more suitable than photocatalytic applications. We believe review trigger shift research laboratory industry reactors.

Hydrogen energy is widely recognized as the cleanest source with zero emissions and represents a pivotal aspect of ambitious carbon neutralization goals. Future trends forecast substantial transition toward employing green hydrogen from fossil counterparts. Therefore, there significant demand for developing efficient stable semiconductor photocatalysts responsive to visible light maximize solar utilization. The perovskite SrTiO3 (STO), cubic chalcogenide oxide featuring structure, cost-effectiveness, flexibility, corrosion resistance, thermal stability, has garnered extensive attention in realm photocatalytic applications. However, due its intrinsic wide band gap, limited amounts photogenerated charge carriers result an unsatisfactory efficiency. Herein, g-C3N4 was employed morphology manipulator on nanofibers. ZnS nanoparticles were then grown situ modified porous nanofibers (g-STO) construct g-STO/ZnS type II nanofibrous heterojunctions. Benefiting synergistic effects large specific surface areas built-in electric field, recombination significantly restrained, endowing composite photocatalyst excellent performance. optimized heterojunction Sr/Zn molar ratio 1:6 displays highest area activity, yielding 1.79 mmol g–1 h–1 production. Comparative analyses pure STO g-STO materials shed photovoltaic properties activity This work establishes facile routine that could allow design effective, high-performance heterojunctions sunlight-driven
