Nanoparticles play a significant role in various fields ranging from electronics to composite materials development. Among them, metal nanoparticles have attracted much attention in recent decades due to their high surface area, selectivity, tunable morphologies, and remarkable catalytic activity. In this review, we discuss various possibilities for the synthesis of different metal nanoparticles; specifically, we address some of the green synthesis approaches. In the second part of the paper, we review the catalytic performance of the most commonly used metal nanoparticles and we explore a few roadblocks to the commercialization of the developed metal nanoparticles as efficient catalysts.

Mesoporous silica supported nanocatalysts have shown great potential in industrial processes due to their unique properties, such as high surface area, large pore volume, good chemomechanical stability and so on. Controllable and tunable synthesis of supported nanocatalysts is a crucial problem. Continuous synthesis of supported nanoparticles has been reported to get uniformly dispersed nanomaterials. Here, a method for continuous synthesis of uniformly dispersed mesoporous SBA-15 supported silver nanoparticles in a coiled flow inverter (CFI) microreactor is described. Compared to Ag/SBA-15 synthesized in the conventional batch reactor and Ag synthesized in continuous flow, mesoporous silica nanocatalysts synthesized in continuous flow are found to have smaller average size (7–11 nm) and narrower size distribution. The addition of capping agents can effectively change the characteristic of catalysts. Moreover, two kinds of support with different surface area and pore size have been added into the continuous synthesis. This method can provide further understandings for the synthesis of uniformly dispersed supported nanocatalysts in continuous flow, especially for mesoporous nanomaterials, which provides the possibilities of large-scale yield process of supported nanocatalysts in industry.

How to improve the conversion efficiency and the stability of dye-sensitized solar cells (DSSCs) are two major problems. Furthermore, reduction of the manufacturing cost of DSSCs and large-scale manufacture are also very important factors. As a raw material, commercial P25 would be used for large-scale manufacture of TiO2paste with simple preparation procedure. However, there are several drawbacks for P25 such as the low surface area of P25 powder and the poor connectivity among particles in film using tradition P25 paste without modification. In this paper, we introduced a simple modified method by adding high surface area anatase TiO2into pure P25 paste. The photoelectric conversion performances of DSSCs based on these photo-electrodes were tested. The results show that the open-circuit voltage, the fill factor and the energy conversion efficiency of the modified electrode were increased. It is found that the modified P25 films have fast electron transportation and a slow charge recombination. We conclude that through adding the anatase TiO2nanoparticles to the P25 paste with high surface area, it can not only improve the particles connectivity among inside the films, but also enhance the efficiency of DSSCs.
