Impact of small promoter amounts on coke structure in dry reforming of methane over Ni/ZrO₂

Abstract

Choosing the correct alkali metal as a promoter not only reduces coke formation in dry reforming of methane but also removes coke via gasification.

A new automated synthesis of a coke-resistant Cs-promoted Ni-supported nanocatalyst for sustainable dry reforming of methane

“…On the other hand, several promoters such as noble metals, alkali, alkaline earth, and rare metals have been used to promote the performance regarding the activity and stability of Ni nanocatalysts. [26][27][28][29][30] In recent years, automated devices and high-throughput experiments have been developed for the synthesis and evaluation of nanomaterials. [31][32][33][34][35] In addition, computational simulation using density functional theory (DFT) of surface reactions has become an effective tool for the design and performance elucidation of new catalysts by using energies calculated from the activation and reaction of active nanomaterial surfaces.…”

Highly active and stable cobalt catalysts with a tungsten carbide-activated carbon support for dry reforming of methane: effect of the different promoters

“…13–15 Therefore, it remains a great challenge to synthesize the DMR catalyst with excellent activity and stability. To enhance the catalytic performance of the DMR catalyst, numerous studies have been carried out on the effects of the support 16,17 and promoter 18,19 of CH 4 –CO 2 reforming catalysts.CH 4 → C + 2H 2 2CO → CO 2 + C…”

Hydrogen production from CO2 reforming of methane using zirconia supported nickel catalyst

“…To avoid the deposition of carbon, the catalysts can be altered by the addition of promoters, being alkaline and alkaline earth metals. 34 Cao et al ; examined the effect of cerium promoter on the activity of cobalt over gamma-alumina applied in dry reforming of methane. 35 They found that the dispersion of the active metal over the support and its reducibility was markedly improved.…”
