“…We confirmed the results with titania (mainly anatase) support [11], as reported in [7] Alcala et al used fumed silica support (CAB-O-SIL / Cabot Corp.) for supporting Pt and could produce ethanol [3], contrary to Rachmady et al who applied a quite different SiO 2 (Davison, Grade 57) [7]. Using indium co-catalyst, side reactions could be completely eliminated regardless of the support TiO 2 or Al 2 O 3 .…”

“…Rachmady [9]. These catalysts proved to be as poor as the supported Pt catalysts used by Rachmady et al [7] Pt/TiO 2 catalysts were found to be the most active for AA hydrogenation and provided the highest ethanol selectivity (up to 70%) [7]. Evidence was obtained that the reaction involves both metal (Pt) and oxide support phases.…”

“…The significance of catalytic reduction of bioacids to fuel or intermediate material production is steadily increasing, however, only a few studies have been devoted to the acetic acid (AA) transformation [3,[7][8][9]. The literature describes catalysts for AA hydrodeoxygenation (HDO) comprised of one or more noble metals of Group VIII dispersed on oxides of elements of Group III/A or IV/A.…”

Acetic acid hydroconversion over mono- and bimetallic indium doped catalysts supported on alumina and silicas of various textures

Consecutive hydroconversion of acetic acid (AA) to ethanol was compared over monometallic and novel bimetallic (containing In as guest metal) catalysts on alumina and silica supports (inter alia highly ordered SBA-15) of different porosity and pore structure. The transformation was studied in a fixed bed, flow-through reactor in the temperature range of 220-380°C using hydrogen flow at 21 bar total pressure. AA hydroconversion activity of Cu and Pt catalysts and the yield of selectively produced alcohol were increased drastically by applying SBA-15 as highly ordered, mesoporous silica support instead of alumina. The most active nickel catalysts do not allow the selective addition of hydrogen to carbon-oxygen bonds independently of supports producing mainly CH 4 ; however, indium doping can completely eliminate the hydrodecarbonylation activity as found in earlier studies. The textural properties of studied silica supports of various textures such as SBA-15, CAB-O-SIL, and Grace Sylobead have a profound impact on the catalytic performance of Ni and Ni 2 In particles.

Supported metal catalysts are comprised of small metal nanoparticles dispersed on the surface of a support material. Previously, the role of the support oxide was commonly thought to be limited to provide large metal surface areas. However, it is now generally accepted that the activity and selectivity of these catalysts are dependent on the type and composition of the support used [1][2][3] or even on thermal pretreatment conditions of catalysts consisting of the same metal and support [4]. In other words, the role of the support goes well beyond strictly physical phenomena such as increasing the surface area, and the specific interaction of the support with the active phase often controls the course of a catalytic reaction.Understanding the effect of the support oxide on the properties of metal nanoparticles is a challenging subject because it opens a way towards modeling and tuning of the catalytic properties by a deliberate choice of the support oxide [5][6][7][8]. As a consequence, gaining an insight into the interfacial structure between metal nanoparticles and their support, particularly under relevant reaction conditions, has been an important topic in the field of heterogeneous catalysis for decades [9,10]. Therefore,
