Methanol steam reforming for hydrogen production over NiTiO3 nanocatalyst with hierarchical porous structure

“…According to our previous studies, the hydroxyl group on the surface of metal oxide was one of the important reaction intermediates in the reforming reaction, 38 so the influence of acidity and alkalinity on the catalytic performance was extremely important. For Ni–Ti–O x catalyst, TiO 2 was the main component, and the coordination charge number of oxygen was −2/3.…”

Toluene Steam Reforming over Ni/CeZrO2—The Influence of Steam to Carbon Ratio and Contact Time on the Catalyst Performance and Carbon Deposition

“…In recent years, several works have been published on the intentional production of CNTs (together with H 2 ) during steam reforming processes. Those works relate to the SR of formaldehyde over NiO/MoO 3 at 300-600 • C [34], the SR of ethanol over Ni/CaO at 600 • C [35], or the "pyrolysis-catalytic" SR of used tires over Ni/Al 2 O 3 at 900 • C [36]. CNT S are often produced in the reaction of CO disproportionation or CH4 dehydrogenation.…”

Na Promotion of Pt/m-ZrO2 Catalysts for the Steam Reforming of Formaldehyde

“…As such, researchers have been investigating sustainable liquid chemical carriers of hydrogen, such as biorenewable ethanol (21 MJ/L) [1][2][3][4][5][6], methanol (15.6 MJ/L) [4,[7][8][9], glycerol [3,4,10,11] and formic acid [12]. In contrast, there are only a few studies on the use of formaldehyde for the production of hydrogen [13][14][15][16][17][18][19][20][21] Although pure formaldehyde is a colorless gas that polymerizes into paraformaldehyde, it can be stored as an aqueous solution as formalin, and it is typically stabilized by methanol. Thus, it is important to examine the reactivity of formaldehyde in its own right as a potential chemical carrier of hydrogen.…”

“…A few studies [12,13,17,18] investigated formaldehyde steam reforming (FSR) on nickel catalyst because of its good C-O, C-C and C-H bond cracking capability. Unsupported NiO, MoO 3 and NiO/MoO 3 were studied by Jin et al [17].…”

Unsupported NiO, MoO 3 and NiO/MoO 3 were studied by Jin et al [17]. The authors found that the catalytic synergy between NiO and MoO 3 improved the hydrogen selectivity compared to NiO and MoO 3 systems.…”
