“…80% yield [34]. This reaction was recently applied to a micro-reaction system by Matsushita et al [35,36]. Kohtani et al recently demonstrated that the P25 TiO2 powder exhibited the excellent photocatalytic activity to hydrogenate several aromatic ketones into corresponding secondary alcohols under the combination of UV light irradiation and deaerated conditions in ethanol as summarized in Table 3 [37].…”

“…using titanium dioxide was reported in 2006. 42 This report also focuses on full miniaturisation, and UV-LEDs with an emission of 365 nm were chosen. Quartz microreactors were fabricated with a catalytic coating on the bottom and sides of the channels (width 500 mm, depth 100 mm and length 40 mm).…”

The use of a confined space in which to carry out reactions has proven popular in recent years, as demonstrated by the large volume of work published on 'molecular microreactors' such as zeolites, micelles and nanoparticles. This article looks at reactions in microstructured reactors, also known as microchannelled reactors or microreactors. In general, these consist of a 'chip' with narrow channels etched into it. Microstructured reactors have been the subject of several review articles to date, focusing on preparation, types of reactions that may be carried out and on the potential for 'green' applications. However, the use of microstructured reactor technology in photochemistry has, until now, not been subject to review. This perspective aims to outline the work done to date in this area and in particular to demonstrate the advantages and future prospectives of this technology in photochemical processes. Photochemistry in microstructured reactors is an emerging area of interest and to date has demonstrated significant potential as a viable alternative to traditional photochemical synthesis.

“…The use of narrow monolith channels [9] or microreactors [10][11][12][13][14] improves mass transfer, especially in the liquid phase applications, and considerably increases the specific illuminated area. Separation of total flow into narrow channels also simplifies scale-up, which in this case is achieved by numbering up of parallel tubes.…”
