“…This approach finally took us to solvothermal synthesis. Although the objectives stated above were not fully achieved, and additional efforts are needed to realize them, a set of studies on silver thiolates [4][5][6][7][8][9] is now complete, which we are reporting here.…”

“…The appearance of the S _ H stretching band at 2390 cm -1 is ascribed to the newly formed S _ H bond in the intermediate species 31) . Furthermore, the S _ H stretching band at 2567 cm -1 is due to the S _ H bond of the thiol group contained in adsorbed TBT on H-FAU-2.8 32) . These findings suggest that TBT decomposition over H-FAU-2.8 occurs via the surface reaction as shown in Scheme 1.…”

Catalytic direct decomposition of t-butanethiol (TBT) into hydrogen sulfide over zeolites without hydrogen addition was examined as a new desulfurization process for fuel cell systems. TBT is a widely used odorant in pipeline natural gas, and was easily decomposed into hydrogen sulfide and isobutene over H-Y and H-beta at low temperatures of 25-150 . However, catalyst deactivation of H-beta was observed at 60 and oligomerized products of isobutene were observed on the catalyst surface after long reaction times. The deactivation rate of TBT decomposition over H-beta increased with higher acid amounts of H-beta. The amount of oligomerized products deposited on the catalyst increased with lower TBT conversion in the initial stage of reaction. The deposition of oligomerized products and catalyst deactivation decreased after several hours. The amount of the oligomerized products deposited on the catalyst reached approximately 6 wt% after 8 h and remained constant after 125 h over H-beta (Si/Al 92.5) at 150 . The initial TBT conversion was constant during 125 h.

“…39 In addition, the alternatively strong and weak peaks have likely arisen from a fine structure associated with the interstack spacing. From the limited data obtained at present, it is proposed that the driving force to form a 3-D arrangement, such as a lamellar structure, 40 is due to the strong tendency to agglomerate between the Au@TOAB nanoparticles. On the other hand, the strong interaction between the inner core and outer shell for Au@TOAB-DT and Au@DT nanoparticles led to a predominantly 2-D structure.…”

Long-range order, uniform in size, and regular in shape two-dimensional (2-D) arrays of core-shell structure Au nanoparticles have been synthesized. A reaction involving the displacement of the outer shells from tetraoctylammonium bromide (TOAB) to dodecanethiol (DT) molecules was used to form Au@TOAB-DT nanoparticles at room temperature (RT). The displacement reaction has used both superior size and shape control of Au@TOAB nanoparticles and uniform dispersion capability of Au@DT nanoparticles to achieve an extraordinarily large in extent (3 µm ϫ 3 µm), regular nanoparticle lattice structure. From ultraviolet (UV)-visible spectra, it was inferred that the interaction between the inner core and outer shell of Au@TOAB nanoparticles is weaker than that of Au@TOAB-DT and Au@DT samples. As a result, the ability of the TOAB outer shell to protect the Au@TOAB nanoparticles is weaker so that the system is more prone to agglomerate. On the other hand, the strong interactions between the inner core and outer shell for Au@TOAB-DT and Au@DT nanoparticles led to a predominantly 2-D structure.
