“…Previously, several microchannel reactors have been tested [17][18][19][20] in order to determine the best design of microreactors. The one tested in this research is composed of a microchannel with a serpentine shape engraved in a stainless steel support.…”

Among the possible solutions for the intensification of photocatalytic reactions, the use of microreactors is emerging. Such an approach was applied to the photodegradation of Ifosfamide in a flow microreactor with an immobilized catalyst composed of ZnO sensitized with CuInZnxS2+x quantum dots. The conversion yield at a low flow rate was investigated. A computational flow simulation allows to determine an apparent constant rate and the diffusion coefficient towards the photocatalyst surface. Photocatalytic degradation of Ifosfamide can be fitted by the Langmuir-Hinshelwood model. The Sherwood number and the average value of Damköhler show that the photocatalytic reaction under our experimental conditions is limited by the mass transfer.

“…Corbel et al. [ 108 ] prepared a rectangular microchannel reactor in an epoxy resin by SLA, then coated the reactor with TiO 2 for photodegradation of salicylic acid, and found that with the increase of channel length, the activity of the reactor increased. DLP, which is similar to SLA, has many more advantages.…”

3D printing is a fabrication method that has attracted worldwide attention in recent years, providing a convenient and economical method for the fabrication of 3D structures. With the development of this technology and the reduction of operating costs, the application of 3D printing is greatly expanded. This paper focuses on the application progress of 3D printing in the preparation of photocatalysts. Considering the advantage that photopolymerization-based 3D printing technology can better control the structure and active component distribution of photocatalytic products, the realization possibility of one-step digital light processing (DLP) printing photocatalyst products is particularly prospected. In addition, the latest research progress of photocatalytic materials and 3D printing technology is also summarized, and the problems that need to be broken through in the future development of DLP-3D printing technology are discussed.

“…When a kinetic regime cannot be assumed or estimating non-dimensional groups a priori is not easy, different approaches have been used. Corbel et al [49] examined the degradation of salicylic acid using a 70-mm-long channel, with a cross-sectional rectangular section of about 1 × 0.5 mm, with immobilized TiO 2 and low flow rates of the order of 2 mL•h −1 . Navier-Stokes equations were coupled with Equation (2) for the mass transfer limitations and the Langmuir-Hinshelwood rate law and solved using the numerical software COMSOL.…”

“…Although some authors suggested the possibility of direct use of these devices for water treatment by numbering up units [25,42], this seems a fairly unrealistic and antieconomic scenario, with very few possible niche applications in the treatment of small volumes of water for specific applications. Only a limited number of papers have addressed the use of microreactors for the estimation of intrinsic parameters and mechanism identification, which can be used for the scale-up of AOPs for wastewater treatment, which, in fact, is the most promising application [9,11,12,23,[43][44][45][46][47][48][49][50][51][52][53][54]. In this sense, there is still extensive room for improvement and exploitation of this technology for the design and scale-up of such tertiary treatments.…”

With the increasing number of recalcitrant pollutants in wastewater treatment plants, there will be a stringent need for rapid and convenient development of tertiary treatment processes such as advanced oxidation processes (AOPs). Microreactors offer a great opportunity for ultrafast and safe intrinsic kinetic parameters determination, by-products identification, and ecotoxicity assessment. Despite the considerable potential of these devices, they have been mostly used for catalyst screening or pseudo-first order kinetics determination, not allowing for knowledge transfer across scales. This work offers an overview of the adoption of micro- and photo-microreactors for intrinsic kinetics investigations in the field of AOPs to guide future research efforts.
