Sandwich-structured nickel/kaolinite catalyst with boosted stability for dry reforming of methane with carbon dioxide

Enhancing Catalytic Performance with Sol‐Gel Hydrotalcite‐Derived Nickel Oxide Catalysts for Dry Reforming of Methane: An Examination on Reactivity and Coke Formation

“…[63] The catalyst eliminates adsorbed coke through confinement effects provided by metal particles. [78] Particles and NiO are protected from coke encapsulation (13-26 nm), [79,80] as shown in Figure 9.…”

Confinement effects over Ni-based catalysts for methane dry reforming

“…Sandwich structures are also used in the design of anti-sintering and anti-coking catalysts, such as silica@Ni@silica, 90 LDH-derived Ni x -V-MgAl catalysts, 91 and Ni/NKaol (nanosheets kaolinite). 92 Boron nitride is widely used to design sandwich structure catalysts due to its unique electronic and geometric structure. 93 Zhang et al achieved important advances in this area.…”

In situ fabricating a Rh/Ga2O3 photothermal catalyst for dry reforming of methane

“…1,2 The DRM reaction is capable of converting greenhouse gases (CH 4 and CO 2 ) into syngas (a mixture of H 2 and CO), contributing to carbon neutrality. 3,4 However, the conversion of CO 2 and CH 4 via the conventional DRM process always needs high temperatures (>800 °C), which leads to the sintering of active components, carbon deposition, and large energy consumption. 5,6 Therefore, to solve the aforementioned challenges, it is crucial to carry out DRM reactions under mild conditions.…”
