“…In this context, the immobilization of TiO 2 on the membrane surface is the best solution for combining the two processes: photocatalysis and membrane separation. The immobilization of TiO 2 on the membrane surface was shown to be useful in the mitigation of fouling [23][24][25][26][27] and is expected to contribute to the degradation of compounds retained in the concentrated retentate produced.…”

A new hybrid photocatalytic membrane reactor that can easily be scaled-up was designed, assembled and used to test photocatalytic membranes developed using the sol-gel technique. Extremely high removals of total suspended solids, chemical oxygen demand, total organic carbon, phenolic and volatile compounds were obtained when the hybrid photocatalytic membrane reactor was used to treat olive mill wastewaters. The submerged photocatalytic membrane reactor proposed and the modified membranes represent a step forward towards the development of new advanced treatment technology able to cope with several water and wastewater contaminants.

“…The mechanism therefore seemed to be more complex than a simple nucleophilic attack on the titanium surface and subsequent M-O bond cleavage, as it has been suggested for silica. Also the behavior of this modified material in different applications [2,23,[25][26][27][28][29] is significantly different when compared to other modification methods, even though the organic moiety is the same [23][24][25].…”

“…[22][23][24][25] Having a direct bond between the surface and the organic group (M-R) can prevent these unwanted interactions, providing unique behavior in application. [2,23,[25][26][27][28][29] This can be achieved by using organometallic reactants.…”

“…The former are made up of inorganic non-metallic solids (either nonmetallic or metallic compounds) and includes clay (plastic materials), silica (filler), and feldspar (fluxes) while the latter are made up of oxides, nitrate compounds, carbides, and non-silicate glass [ 105 ]. Regarding advanced ceramics, there is a growing interest in ceramic membranes based on Al 2 O 3 , TiO 2 , SiO 2 , and ZrO 2 that demonstrate good performance in water treatment, turbidity removal, desalination, wastewater treatment, and other important industrial applications, apart from other advantages inherent in energy saving [ 115 , 116 ]. However, the preparation of nanocomposites using carbon, polymer, and ceramic materials is still at an early stage, requiring further investigation [ 117 ].…”

Supported TiO2 in Ceramic Materials for the Photocatalytic Degradation of Contaminants of Emerging Concern in Liquid Effluents: A Review

et al. 2021

The application of TiO2 as a slurry catalyst for the degradation of contaminants of emerging concern (CEC) in liquid effluents has some drawbacks due to the difficulties in the catalyst reutilization. Thus, sophisticated and expensive separation methods are required after the reaction step. Alternatively, several types of materials have been used to support powder catalysts, so that fixed or fluidized bed reactors may be used. In this context, the objective of this work is to systematize and analyze the results of research inherent to the application of ceramic materials as support of TiO2 in the photocatalytic CEC removal from liquid effluents. Firstly, an overview is given about the treatment processes able to degrade CEC. In particular, the photocatalysts supported in ceramic materials are analyzed, namely the immobilization techniques applied to support TiO2 in these materials. Finally, a critical review of the literature dedicated to photocatalysis with supported TiO2 is presented, where the performance of the catalyst is considered as well as the main drivers and barriers for implementing this process. A focal point in the future is to investigate the possibility of depurating effluents and promote water reuse in safe conditions, and the supported TiO2 in ceramic materials may play a role in this scope.
