“…The most popular technique among AOPs is the heterogeneous photocatalysis, where a semiconductor photocatalyst interacts with light of sufficient energy (or of a certain wavelength) to produce reactive oxidizing species, which can lead to the photocatalytic degradation of pollutants [7]. Large scale application of heterogeneous photocatalysis may be constrained, however, by technical challenges mainly related to the effective recovery and extended use of the catalyst particles in a continuous process [8,9]. An alternative promising approach is the immobilization of photocatalysts on porous adsorbents, such as carbon, clays, zeolite, and others, which offer the synergistic combination of adsorption and catalytic degradation of the adsorbed pollutants by UV/visible light irradiation.…”

The synthesis, characterization, and performance of composite photocatalytic adsorbents are investigated in this work using the dip-coating and the electrophoretic coating methods for the deposition of titanium dioxide (TiO 2 ) on porous activated carbon fiber (ACF) substrates. The adsorption and photocatalytic efficiency of the synthesized catalytic adsorbents were compared using phenol as the model pollutant. Both immobilization techniques resulted in composite ACF/TiO 2 adsorbents characterized by large surface area (844.67 ± 45.58 m 2 g −1 ), uniform distribution of TiO 2 nanoparticles on the activated carbon fibers, and high phenol adsorption. The method and the treatment time affected the phenol adsorption, while the highest sorption was determined in the case of the ACF/TiO 2 sample prepared by the electrophoretic coating method (at 20 V) for an electrolysis time of 120 s (7.93 mg phenol g −1 ACF/TiO2 ). The UV-A irradiation of most ACF/TiO 2 samples led to a faster removal of phenol from water as a result of the combined sorption and heterogeneous photocatalysis. The stability and the effective regeneration of the most promising composite photocatalytic adsorbent was proved by multiple filtration and UV-A irradiation cycles.

“…Main approaches with future prospects are represented by MBR (Membrane bioreactor) and PMR (Photocatalytic membrane reactor) technologies. MBR technology uses the combined membrane unit approach (Ćemanović et al 2019), meanwhile, PMR focuses on the photocatalytic reactor approach (Karabelas et al 2018).…”
