Recognizing the emergency of the global climate issue, the current fossil fuel‐based economic structure with massive carbon emission is urgent to be transformed. Catalytic conversion of CO x , as an emerging alternative technology to produce advanced chemicals and fuels, has received enormous attention. Particularly, photothermal CO x conversion, combining the advantages of high efficiency and low pollution, has shown the potential for the production of solar fuels and chemicals, and the progress of this field is accelerating. This review summarizes the fundamentals of photothermal catalysis as well as the state‐of‐the‐art advances of the photothermocatalytic CO x conversion in the three main parts that involve CO x hydrogenation, water–gas shift reaction, and CO2 reforming of CH4. Moreover, the challenges and perspectives are also briefly discussed, which proposes guidance for future investigation of photothermal C1 conversion and anthropogenic carbon cycle.

In this contemporary era of rapid progress, the global demand for energy has reached unprecedented levels, placing considerable strain on existing energy supplies. To address this challenge, synthetic or substituted natural gas (SNG) has emerged as a groundbreaking energy source attained through the methanation reaction of hydrogen and carbon monoxide (CO). This paper unveils a successful synthesis method for fibrous silica zirconia (FSZr) exploiting the microemulsion procedure, subsequently applied in the CO methanation process. The catalyst underwent comprehensive characterization using advanced techniques, including Fourier Transform Infrared (FTIR) spectroscopy, Field-Emission Scanning Electron Microscopy (FESEM), x-ray diffraction (XRD), and N2 adsorption-desorption. The experimental results clearly demonstrate the exceptional catalytic performance of FSZr when compared to commercially available ZrO2. At a temperature of 500 ºC, FSZr achieved a CO conversion and CH4 yield of 20.76% and 11.52%, respectively. The remarkable achievements are credited to FSZr’s distinct fibrous structure, expansive surface area, and exceptional basic characteristics. The heightened surface area facilitates better access to reactive sites, while the strong basic properties enable easier adsorption of the reactant. These combined factors significantly enhanced the effectiveness of the CO methanation procedure. These findings underscore the significance of fibrous morphology in zirconia catalysts for CO methanation, presenting a promising avenue for further research and insights into meeting the global energy demands efficiently.

“…In other words, SNG offers an industrial route to utilize either emissions intensive fuel sources or wastes into fewer emissions energy source. Moreover, SNG takes full advantage of the existing transport & end usage infrastructure of natural gas [5], which is already providing a significant portion of the global energy demand.…”

“…The activity of metallic catalysts were found to be in the following order Ru>Fe>Ni>Co whereas the selectivity towards methane production was found to be Ni>Co>Fe>Ru [6]. Nickel oxide is one of the most widely used catalysts for CO methanation due to its high activity, relatively economic production costs and high Methane selectivity [5]. Unsupported nickel catalyst have considerable limitations in methanation reaction as they are prone to deactivation through thermal sintering and carbon deposition [7] [8].…”

“…Unsupported nickel catalyst have considerable limitations in methanation reaction as they are prone to deactivation through thermal sintering and carbon deposition [7] [8]. Catalytic supports are a very active area of research for CO methanation reactions [5]. This is because the metal-support interaction can influence the catalytic performance through altering catalyst activity and metal dispersion [9] [8] .…”

Synthetic natural gas (SNG) has attracted significant attention over the past years due to its critical role in the future energy mix where it can be produced from multiple sources, including coal, wastes & biomass. Carbon monoxide (CO) methanation is considered one of the major SNG production routes. Nickel oxide catalyst supported on silica extracted from risk husk was prepared using wet impregnation method and characterized using different techniques including XRD, N2 Adsorption, Atomic absorption, XRF & TPR. Distinctively from most of the published previous work, The catalyst performance in progressing CO Methantion reaction was tested in a bubbling fluidized bed continuous flow reactor system at the stoichiometric H2:CO ratio of 3:1 in absence of any other feed constituents. The catalytic runs were conducted at atmospheric pressure, in the temperature range between 200-450 o C and at fluidization velocity equal to four times the minimum fluidization velocity (Umf). CO conversion, CH4 selectivity & CO2 Selectivity were calculated for all runs. Based on the assessment of catalytic runs, fluidized bed reactor system proved to be efficient in ensuring adequate temperature control and uniformity for CO methanation. Optimal results of 97% CO conversion, 81% CH4 selectivity and 21% CO2 selectivity were achieved at operating conditions of temperature of 450 o C, pressure of 1 bara & superficial velocity of 4 Umf. Recommendations for future work in terms of catalyst development and operating conditions were also made based on the results achieved.
