“…As a support, it can form the strong metal-support interaction with the Ni active site. Therefore, the metallic Ni nanoparticles can be well-dispersed on the support, which is further conducive to the improvement of the catalytic activity and anti-coke property of the catalyst (Nabgan et al, 2020). Wang Y. et al (2018b) confirmed that the metal-support interaction of the Ni-Si/ZrO 2 catalyst not only facilitated the formation of small metallic Ni active sites with strong electron donor capability but also maintained the state of the Ni particles under CRM reaction conditions.…”

CO 2 reforming of methane (CRM) can effectively convert two greenhouse gases (CO 2 and CH 4) into syngas (CO + H 2). This process can achieve the efficient resource utilization of CO 2 and CH 4 and reduce greenhouse gases. Therefore, CRM has been considered as a significantly promising route to solve environmental problems caused by greenhouse effect. Ni-based catalysts have been widely investigated in CRM reactions due to their various advantages, such as high catalytic activity, low price, and abundant reserves. However, Ni-based catalysts usually suffer from rapid deactivation because of thermal sintering of metallic Ni active sites and surface coke deposition, which restricted the industrialization of Ni-based catalysts toward the CRM process. In order to address these challenges, scientists all around the world have devoted great efforts to investigating various influencing factors, such as the option of appropriate supports and promoters and the construction of strong metal-support interaction. Therefore, we carefully summarized recent development in the design and preparation of Ni-based catalysts with advanced catalytic activity and enhanced anti-coke performance toward CRM reactions in this review. Specifically, recent progresses of Ni-based catalysts with different supports, additives, preparation methods, and so on, have been summarized in detail. Furthermore, recent development of reaction mechanism studies over Ni-based catalysts was also covered by this review. Finally, it is prospected that the Ni-based catalyst supported by an ordered mesoporous framework and the combined reforming of methane will become the future development trend.

“…Catalysts 2021, 11, x FOR PEER REVIEW 11 of 17 coke combustion occurred in the similar range of 550 °C to 800 °C corresponding to the oxidation of the filament/graphitic carbon species [48], the main type of the catalyst deactivation growing on the poor Ni-ZrO2 interaction. Although the catalysts prepared by the co-impregnation exhibited the similar oxygen mobility and type of coke, the amount of coke on a catalyst with a low content of ZrO2 at the surface as promoter (the 10Ni-1ZrO2/Al2O3 (CI) catalyst) is less than the coke on the catalyst with a high content of ZrO2 at the surface as a coactive species (the 10Ni-10ZrO2/Al2O3 (CI) catalyst).…”

The role of ZrO2 as different components in Ni-based catalysts for CO2 reforming of methane (CRM) has been investigated. The 10 wt.% Ni supported catalysts were prepared with ZrO2 as a support using a co-impregnation method. As a promoter (1 wt.% ZrO2) and a coactive component (10 wt.% ZrO2), the catalysts with ZrO2 were synthesized using a co-impregnation method. To evaluate the effect of the interaction, the Ni catalyst with ZrO2 as a coactive component was prepared by a sequential impregnation method. The results revealed that the activity, the selectivity, and the anti-coking ability of the catalyst depend upon the ZrO2 content, the Ni-ZrO2 interaction, basicity, and oxygen mobility of each catalyst resulting in different Ni dispersion and oxygen transfer pathway from ZrO2 to Ni. According to the characterization and catalytic activation results, the Ni catalyst with low ZrO2 content (as a promoter) presented highest selectivity toward CO owning to the high number of weak and moderate basic sites that enhance the CO2 activation-dissociation. The lowest activity (CH4 conversion ≈ 40% and CO2 conversion ≈ 39%) with the relatively high quantity of total coke formation (the weight loss of the spent catalyst in TGA curve ≈ 22%) of the Ni catalyst with ZrO2 as a support is ascribed to the lowest Ni dispersion due to the poor Ni-ZrO2 interaction and less oxygen transfer from ZrO2 to the deposited carbon on the Ni surface. The effect of a poor Ni-ZrO2 interaction on the catalytic activity was deducted by decreasing ZrO2 content to 10 wt.% (as a coactive component) and 1 wt.% (as a promoter). Although Ni catalysts with 1 wt.% and 10 wt.% ZrO2 provided similar oxygen mobility, the lack of oxygen transfer to coke during CRM process on the Ni surface was still indicated by the growth of carbon filament when the catalyst was prepared by co-impregnation method. When the catalyst was prepared by a sequential impregnation, the intimate interaction of Ni and ZrO2 for oxygen transfer was successfully developed through a ZrO2-Al2O3 composite. The interaction in this catalyst enhanced the catalytic activity (CH4 conversion ≈ 54% and CO2 conversion ≈ 50%) and the oxygen transport for carbon oxidation (the weight loss of the spent catalyst in TGA curve ≈ 7%) for CRM process. The Ni supported catalysts with ZrO2 as a promoter prepared by co-impregnation and with ZrO2 as a coactive component prepared by a sequential impregnation were tested in combined steam and CO2 reforming of methane (CSCRM). The results revealed that the ZrO2 promoter provided a greater carbon resistance (coke = 1.213 mmol·g−1) with the subtraction of CH4 and CO2 activities (CH4 conversion ≈ 28% and CO2 conversion ≈ %) due to the loss of active sites to the H2O activation-dissociation. Thus, the H2O activation-dissociation was promoted more efficiently on the basic sites than on the vacancy sites in CSCRM.

RESUMOA crescente produção de polímeros orgânicos sintéticos para acondicionamento de diferentes produtos de uso humano é uma preocupação global, por causa do aumento no descarte inadequado pós consumo. Essa prática humana representa grave risco ambiental, devido a alta persistência desses polímeros, frente a decomposição natural. O Polietileno Tereftalato, PET muito empregado nas indústrias de bebidas, cosméticos, farmacêutica, alimentar e outros no segmento industrial, já dispõe de tecnologia de reciclagem para recuperação de 100% do PET, e o tratamento de recuperação não produz resíduo tóxico ou infectante. No Brasil, somente cerca de 12% do PET coletado é corretamente reciclado, necessitando de maior incentivo governamental e participação da sociedade civil, na recuperação da matéria-prima e destinação adequada para fomentar a cadeia circular de produção, poupando assim energia e recursos naturais.
