“…In general, impregnation of heterogeneous catalysts on supported metal oxides leads to the stochastic distribution of the size and spatial location of the active NPs within the catalyst volume [ 60 ]. Additionally, CSNs can be engineered via additional synthesis following hydrothermal [ 61 , 62 , 63 ] microemulsion [ 64 , 65 , 66 , 67 ], ball milling [ 68 , 69 ] or ion exchange [ 70 , 71 ] technique. Such additional synthesis steps are important to tailor the water-to-surfactant ratio, thus resulting in a small and narrow particle size distribution inside the shell cage.…”

Carbon-intensive industries must deem carbon capture, utilization, and storage initiatives to mitigate rising CO2 concentration by 2050. A 45% national reduction in CO2 emissions has been projected by government to realize net zero carbon in 2030. CO2 utilization is the prominent solution to curb not only CO2 but other greenhouse gases, such as methane, on a large scale. For decades, thermocatalytic CO2 conversions into clean fuels and specialty chemicals through catalytic CO2 hydrogenation and CO2 reforming using green hydrogen and pure methane sources have been under scrutiny. However, these processes are still immature for industrial applications because of their thermodynamic and kinetic limitations caused by rapid catalyst deactivation due to fouling, sintering, and poisoning under harsh conditions. Therefore, a key research focus on thermocatalytic CO2 conversion is to develop high-performance and selective catalysts even at low temperatures while suppressing side reactions. Conventional catalysts suffer from a lack of precise structural control, which is detrimental toward selectivity, activity, and stability. Core-shell is a recently emerged nanomaterial that offers confinement effect to preserve multiple functionalities from sintering in CO2 conversions. Substantial progress has been achieved to implement core-shell in direct or indirect thermocatalytic CO2 reactions, such as methanation, methanol synthesis, Fischer–Tropsch synthesis, and dry reforming methane. However, cost-effective and simple synthesis methods and feasible mechanisms on core-shell catalysts remain to be developed. This review provides insights into recent works on core-shell catalysts for thermocatalytic CO2 conversion into syngas and fuels

The aim of this study was to prepare and characterize nanocomposites consisting of graphene oxide (GO) and copper ferrite (CuFe2O4) in different doping ratios (1%‐5%) and investigate their potential for storing hydrogen gas. The prepared nanocomposites were characterized using FTIR, XRD, SEM, and TEM. The results showed that hydrogen storage at 20°C was not possible with GO alone, but the incorporation of different proportions of copper ferrite nanoparticles significantly improved the hydrogen storage properties of the composite materials. The optimal percentage of copper ferrite was found to be around 3%, and it was observed that the percentage of ferrite added is crucial in determining the hydrogen storage properties of the nanocomposites. The best hydrogen storage value of 3.3% was achieved at a temperature of 20°C and a pressure of 80 bar within just 60 seconds. The adsorption of the composite material was found to be of the second type, with a re‐creation coefficient greater than 0.97 for all the materials tested, indicating favorable adsorption. The b value was up to 0, further confirming the favorable adsorption. Overall, the results demonstrate that the incorporation of copper ferrite nanoparticles can significantly improve the hydrogen storage properties of graphene oxide, and careful selection of the doping ratio is necessary to achieve the optimal performance. These findings have potential implications for the development of efficient hydrogen storage materials for clean energy applications.
