“…The large surface area and narrow channel depth of microdevices promote better irradiation and improve the photoreaction's efficiency [292]. Naturally, microdevices need to be transparent and manufactured from materials with cut-off wavelengths compatible with the required light, e.g., glass, quartz, silicon, and fluoropolymers [290,[293][294][295]. Photocatalysts can be introduced as an externally mixed colloidal suspension or can be coated (i.e., sol-gel [296], sputtering [297], spray coating [298], spin coating [299], or vapor+solvent depositing [300]) to the internal microchannel surface.…”

Biodiesel is produced on a large scale as an ecofriendly substitute and additive to fossil fuels. Catalytic homogeneous processes using strong acids, alkalis, and natural oils have been realized in industry. However, these traditional methods have several disadvantages, such as the generation of large volumes of waste, high water and reagent needs, use of hazardous reagents, high operation costs, and utilization of valuable feedstocks and catalysis, respec-tively. Different solutions have subsequently been investigated, such as cheap alternative feedstocks, co-solvents and catalysts, sustainable operational conditions, advanced reactor designs and scales, and advantageous pre-and post-reaction treatments. This review explores and analyzes the main aspects of current biodiesel technologies and opportunities. It also describes some advanced improvement strategies.

“…There are several methods for the synthesis of Pd nanoparticles (75)(76)(77)(78)(79)(80)(81)(82), and various supports have been used to immobilize Pd NPs such as carbon, mesocellular foams, carbon nanotubes, and silica. Particles can be prepared in the presence of the supports, or ex-situ and then immobilized on supports.…”

“…Our group developed a facile procedure for the synthesis of well-defined Pd NPs that were stabilized by thioether ligands (80)(81)(82). The synthetic procedure included the pyrolysis of palladium acetate [Pd 3 (OAc) 6 ] in toluene, using n-dodecyl sulfide as the stabilizing agent.…”

The design and synthesis of well-defined metallic and bimetallic nanoparticles (NPs), their characterization, and the assessment of how their size and shape-dependent properties influence their applications are important areas of investigation for advancing green technologies that protect the environment. This chapter reviews recent advances in the design and synthesis of metallic, bimetallic and semiconductor nanoparticles and their emerging applications in the production of energy and chemicals from biorenewable materials. This contribution focuses on nanoparticle-mediated processes for biomass transformation that include hydrogenation, hydrogenolysis, decarboxylation, small molecule oxidation, conversion of cellulosic materials, hydrocarbon formation, and production of fuel cells. These processes all have significant potential for development of green technologies.

“…In contrast to the in situ formation of Pd NPs, pre‐made n ‐dodecyl sulfide (NDS)‐stabilized Pd, Pt, and Ru NPs were immobilized by coordinating them to the primary amine groups on the microchannel channel surface ( 216 , Figure 9). 123 The catalytic device was tested for the hydrogenation of 6‐bromo‐1‐hexene to 1‐bromohexane. The Pd and Pt catalysts (90% conversion) displayed 2.5 times higher activity than the Ru catalyst (38% conversion).…”

This review surveys the recent developments to perform heterogeneous catalysis in continuous‐flow microreactors. Three different types, namely, (i) packed‐bed, (ii) monolithic, and (iii) wall‐coated approaches are discussed to implement various kinds of catalysts in a microreactor. In addition, the applications of these supported catalysts to perform a variety of organic reactions are described. Furthermore, advantages of catalytic microreactors over classical batch reactors on one or more aspects of the reaction, such as rate, conversion, selectivity, and enantioselectivity are presented.
