“…It should be noted that bimetallic or trimetallic supported catalysts have been also prepared by FSP as seen in propane [355]. It was found that the addition of Ce during FSP synthesis resulted in higher Pt dispersion as well as improved catalytic activity and stability than the non-promoted Pt-Sn/Al 2 O 3 .…”

Manufacturing of nanostructured materials and functional devices offers many exciting opportunities for scientists and engineers to contribute substantially in renewable energy utilization, environmental compliance, and product development. In the past two decades, gas-phase flame synthesis has not only proved to be one of the most scalable and economical technologies for producing well-controlled nanostructured materials, including single metal-oxide, mixed-oxide nanocomposite, and carbon nanostructures, but also has been recognized as a new low-cost fabrication method of nano-devices. In this paper, we focus our review mainly on the recent trends in specific applications of flame aerosol synthesis in the last decade, e.g., usage of a substrate in stagnation geometry with controlled particle temperature-time history, application of external fields to control particle characteristics, development of advanced spray technique for doping synthesis of nanocomposites of multicomponent metal oxides or carbon-metal oxides, and fabrication of nanomaterial-based functional devices. For the possibility to improve the design and operation of flame aerosol reactors, in situ optical diagnostics for either gas phase or particle phase in flame field, along with multi-scale modeling and simulation employing gas-phase chemistry, population balance method, molecular dynamics, and nanoscale particle dynamics are summarized.

“…The flame-made Pt/TiO 2 catalysts were carried out using a spray flame reactor similar to our previous studies [19,20,23]. Platinum actetylacetonate and titanium (IV) butoxide of reagent grade from Aldrich were used as platinum and titanium precursors, respectively.…”

“…Flame-made nanomaterials find application in many catalytic reactions such as oxidation, photocatalytic degradation [14], lean-NO x storage reduction [15], hydrogenation [13,[16][17][18], and dehydrogenation [19,20]. Interestingly, superior catalytic performances have been reported for the flame-made catalysts compared to those prepared by conventional impregnation method, for example, Pd/Al 2 O 3 in the hydrogenation of ethyl pyruvate [21], Pt/Al 2 O 3 in the dehydrogenation of propane [20], and Pd/TiO 2 in the liquid-phase selective hydrogenation of 1-heptyne [22].…”

“…Recent studies show that Pd/SiO 2 synthesized by FSP method exhibited higher hydrogenation activity in the liquid-phase selective hydrogenation of 1-heptyne compared to the ones prepared by conventional impregnation (Mekasuwandumrong et al 2009). Al 2 O 3supported Pt-based bi-and tri-metallic catalysts were developed for dehydrogenation of propane to propylene (Pisduangdaw et al 2009(Pisduangdaw et al , 2011. Stronger metalsupport interaction in the flame-made nanoparticles is found to produce highly beneficial effects in such reactions.…”

First we survey the scope and level of research activities in nanoparticle technology (NPT) in ASEAN by looking at relevant international journal publications (2006)(2007)(2008)(2009)(2010)(2011)(2012) in terms of absolute numbers (AN), numbers of publications per million population (PMP) and per billion USD GDP (PBG). Obviously, the statistics show that, within ASEAN, the strength of Singapore covers a wide range of nanotechnology fields and applications, including carbon materials, biosensors, bioelectronics, and pharmaceutics. Malaysia places emphasis on alloys & compounds, carbon materials, and separation technology. Thailand s emphasis is on molecular modeling, carbon materials, and biosensors. When classification is made on the morphology of nanoparticles mentioned in the titles, the topmost are nanotubes (including CNT, SWCNT, MWCNT) at 392 out of 612 (64.1%), followed by generic nanoparticle/ nanopowder and nanofiber (including nanowire, nanorods). Next we look closer at 2 nanoparticle R&D organizations in Thailand, namely, CEPT (CU) and NANOTEC together with their alliances. The interest in nanotechnology of SCG (Siam Cement Group), a leading Thai industrial conglomerate, will also be briefly introduced. .
