“…It is noteworthy that just 10 mg of catalyst was used in this degradation process and compared with other organic photocatalysts such as the perylene-3,4,9,10-tetracarboxylic diimide (PDINH) supramolecular system and g-C 3 N 4 as reported in the literature [5], its ability to degrade phenol was superior. In addition, our degradation experiment was performed under visible light and the degradation ability of other visible materials is incomparable [31].…”

“…Trapping experiments were measured to test the active species of the photocatalysis reaction. Figure 13 shows the photodegradation rates for phenol by CTAB-TCPP aggregates in the presence of hole scavenger (EDTA-2Na) [39], superoxide radical scavenger (p-BQ) [40] and hydroxyl radical scavenger (IPA) [31], respectively. The degradation rate was reduced drastically in the presence of p-BQ, revealing that superoxide radical (•O 2 − ) was the main oxidative species in the degradation reaction.…”

Metal-free porphyrin with good planarity is beneficial to π–π stack interactions, which promotes electron coupling and the separation and transfer of photogenerated carriers. It is necessary to develop metal-free porphyrin-based photocatalysts and exploit the photocatalytic mechanism. Herein, metal–free porphyrin (5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin, TCPP) was self-assembled through an acid-based neutralization reaction and mixing dual-solvents under surfactants to form different aggregates. Morphology structures, optical and optoelectronic properties of the TCPP aggregates were characterized in detail. TCPP self-assemblies showed higher photocatalytic activities for the degradation of phenol under visible light than untreated TCPP powders, and the aggregates of nanorods formed through the acid-based neutralization reaction in the presence of hexadecyl trimethyl ammonium bromide (CTAB) possessed 2.6 times more activity than the nanofiber aggregates formed through mixing dual-solvents. It was proved that self-assembly methods are crucial for controlling the aggregation of porphyrins to form different aggregations, which have a profound impact on the photocatalytic activity.

“…Although significant works using pure and modified C 3 N 4 as an efficient potential photocatalyst for CO 2 reduction have been reported, tests on photocatalyst stability and controls in the absence of CO 2 are usually not presented [91][92][93]. Some authors report that the photocatalysts maintained a percentage of stability after several photocatalytic runs [94]. When the g-C 3 N 4 stability is evaluated, the changes in product yield with time are observed, wherein the activity is reported to be constant with reuse [95][96][97].…”

This paper presents an overview of recent reports on photocatalytic membrane reactors (PMRs) in organic synthesis as well as water and wastewater treatment. A brief introduction to slurry PMRs and the systems equipped with photocatalytic membranes (PMs) is given. The methods of PM production are also presented. Moreover, the process parameters affecting the performance of PMRs are characterized. The applications of PMRs in organic synthesis are discussed, including photocatalytic conversion of CO2, synthesis of KA oil by photocatalytic oxidation, conversion of acetophenone to phenylethanol, synthesis of vanillin and phenol, as well as hydrogen production. Furthermore, the configurations and applications of PMRs for removal of organic contaminants from model solutions, natural water and municipal or industrial wastewater are described. It was concluded that PMRs represent a promising green technology; however, before the application in industry, additional studies are still required. These should be aimed at improvement of process efficiency, mainly by development and application of visible light active photocatalysts and novel membranes resistant to the harsh conditions prevailing in these systems.

“…26 Cui et al enhanced the photocatalytic degradation activity towards organic pollutants through selfassembly perylene tetracarboxylic acid diimide polymer nanostructures incorporating TiO 2 nanoparticles. 27 However, few literatures reported photocatalyst materials with bay area substituted PDIs, although such substituents can signicantly change the electronic structures and photochemical properties of PDIs. It is because that this kind of PDIs was difficult to form well-dened nanostructures due to the distortion of p-p stacking.…”
