“…This could be attributed to the introduction of Ce species which promotes the dispersion of Ni species, thus increasing the S BET and V pore . This result is consistent with the results reported by Arbag et al 36…”

“…At the same time, a portion of the carbon deposits in the reaction can react with CeO 2 at high temperatures to generate new oxygen holes (C + 4CeO 2 → 2Ce 2 O 3 + CO 2 ), causing some amounts of the carbon deposits to be consumed. It is further proved that the addition of the additive CeO 2 significantly improves the antisintering and antioxidation properties of Ni in the catalyst , and inhibits the formation of carbon deposits in the catalyst, and the catalyst exhibits excellent stability.…”

In this paper, a molecular sieve (VSiO 2 ) prepared from modified vermiculite is used as a support, and a multilayer mesoporous catalyst, Ni-VSiO 2 , is prepared while the active components are loaded in one step by the precipitation method. The catalyst is further modified by adding additives Ca and Ce to prepare the catalyst Ni-5x-VSiO 2 (x = Ce, Ca) and is used for the dry reforming of methane reaction. The catalyst is characterized by X-ray fluorescence, Brunauer−Emmett−Teller analysis, scanning electron microscopy, hydrogen temperature-programmed reduction test, transmission electron microscopy, thermogravimetric analysis, and other technical means. The result shows that under a normal pressure of 750 °C, the catalyst Ni-Ca-VSiO 2 has good stability. The catalyst Ni-Ce-VSiO 2 has good activity, stability and carbon deposition resistance, and the conversion rates of CO 2 and CH 4 are 88% and 78%, respectively. This is because the mesoporous structure allows Ni nanoparticles to enter the pores of the catalyst support, thereby inhibiting the aggregation of the active component Ni and improving its sintering resistance. CeO 2 additives provide more oxygen vacancies to inhibit the formation of carbon deposits. At the same time, the strong interaction between the active component Ni and the additive CeO 2 is also beneficial to improve its sintering resistance.

“…These detrimental effects lead to the deactivation of the catalyst and require it to be repaired or replaced by a new catalyst. 141 , 144 Elbaba and Williams studied hydrogen production from waste tires through two-stage pyrolysis gasification. 145 Ni/Al 2 O 3 and Ni/dolomite were used as catalysts, and their deactivation was investigated over four cycles of use.…”

Sustainable energy production is a worldwide concern due to the adverse effects and limited availability of fossil fuels, requiring the development of suitable environmentally friendly alternatives. Hydrogen is considered a sustainable future energy source owing to its unique properties as a clean and nontoxic fuel with high energy yield and abundance. Hydrogen can be produced through renewable and nonrenewable sources where the production method and feedstock used are indicators of whether they are carbon-neutral or not. Biomass is one of the renewable hydrogen sources that is also available in large quantities and can be used in different conversion methods to produce fuel, heat, chemicals, etc. Biomass gasification is a promising technology to generate carbon-neutral hydrogen. However, tar production during this process is the biggest obstacle limiting hydrogen production and commercialization of biomass gasification technology. This review focuses on hydrogen production through catalytic biomass gasification. The effect of different catalysts to enhance hydrogen production is reviewed, and social, technological, economic, environmental, and political (STEEP) analysis of catalysts is carried out to demonstrate challenges in the field and the development of catalysts.
