Catalytic production of hydrogen through aqueous-phase reforming over platinum/ordered mesoporous carbon catalysts

Aqueous-phase reforming of xylitol over Pt/C and Pt/TiC-CDC catalysts: catalyst characterization and catalytic performance

“…The catalysts with bigger Pt clusters supported on alumina demonstrated higher TOF values in terms of the hydrogen production. A recent study by Kim et al 49 showed that in the case of Pt catalysts supported on carbonaceous CMK the hydrogen production rate in APR of ethylene glycol increases with an increase of the metal loading. Structure sensitivity was therefore observed for C 2 -C 3 polyols only.…”

“…12,32,38 Carbon supports for Pt catalysts in the APR process have recently attracted much scientific attention. Such carbon supports as Vulcan active carbon (Pt 12,32,38,39 and Pt-M, M = Re, Ru, Os, Fe, Cu, Sn, Ir 15 ), activated carbon (Pt, 23,40,41 Pt-Re 42,43 ), carbon fibers (Pt and Pt-Ru), 44 single-walled carbon nanotubes SWNTs (Pt and Pt-Co), [45][46][47][48] ordered mesoporous carbon CMK-3 (Pt, 49 Pt-Mn, 50 Pt-Re 51 ) have been successfully investigated in the APR of polyols. These supports possess high hydrothermal stability under APR conditions (compared to the most investigated catalysts Pt on γ-Al 2 O 3 , where the alumina support might slowly transform into boehmite during water exposure at elevated temperatures and pressures 35,52 ), large surface area and good activity and hydrogen selectivity via APR.…”

Progress in the aqueous-phase reforming of different biomass-derived alcohols for hydrogen production

“…In the APR reaction, not only the nature of the support has an influence on the activity but also the distribution of the products on the surface affects the activity. Kim et al (2011; examined the APR catalytic activity over monometallic Pt catalysts and bimetallic Pt-Mn catalysts on different supports. The hydrogen production rates among these catalysts followed the order: Pt/CMK-3> Pt/activated carbon (AC)>Pt/γ-Al 2 O 3 >Pt/Catapal B.…”

“…Kim et al (2011) examined a series of Pt-based catalysts supported on ordered mesoporous carbon (CMK-3) with different Pt loadings. The catalytic performance of these materials with different supported catalysts for the APR reaction is shown in Table 1.…”

“…Different types of catalysts were applied in the APR of ethylene glycol, including noble metal-based catalysts, such as Pt, Pd, Rh, Ru, and Ir (Liu et al, 2008;Skoplyak et al, 2009;Kim et al, 2011;, Sn modified Raney Ni , NiMgAl layered double hydroxide catalysts, Ni/Sn/Al hydrotalcite derived catalysts (Pan et al, 2012), rapidly quenched skeletal Ni (Xie et al, 2006), non-pyrophoric Ni catalysts (Zhu et al, 2008), and Co/ZnO catalysts (Chu et al, 2011).…”
