One-pot oxidative-adsorptive desulfurization of model and real fuel using micro-mesoporous SiO2 aerogel supported MoO3

Kinetic modeling of oxidative dehydrogenation of propane with CO2 over MoOx/La2O3–Al2O3 in a fluidized bed

“…According to the classification by International Union of Pure and Applied Chemistry (IUPAC), the adsorption–desorption isotherm displayed in Figure 6A is a type IV with an H1 hysteresis loop. This type of isotherm shows that the pores of the material is cylindrical in shape and the catalyst is mesoporous in nature 32 . The pore size distribution as can be seen in Figure 6B.…”

“…This type of isotherm shows that the pores of the material is cylindrical in shape and the catalyst is mesoporous in nature. 32 The pore size distribution as can be seen in Figure 6B. It shows that the synthesized material exhibits a unimodal pore diameter distribution of about 55 Å.…”

Cobalt-based metal–organic framework for desulfurization of thiophene as a model fuel

“…Thus, separation by an adsorptive method is in vogue for MOF materials compared to other adsorbents, such as activated carbon, 6,11 modied, functionalized or heteroatomdoped carbon, 12 zeolites, 13 graphitic materials, 14 and metal oxide composites. 12 MOFs have been investigated for desulfurization processes because of their advantages in terms of porosity, stability, and optimum pore sizes. However, only a few MOF structures have been explored for adsorptive desulfurization, and most of these materials display limited capacity for adsorption.…”

SiO2 Nanostructure-Based Aerogels with High Strength and Deformability for Thermal Insulation

“…In 1931, the paper “Coherent expanded aerogels and jellies” in Nature is recognized as a symbol of the birth of the SiO 2 aerogel . As a multifunctional material, the SiO 2 aerogel has much promise in heat preservation, catalysis, adsorption, optics, and energy due to its structural characteristics such as high specific surface area, low density, high porosity, and mesoporous interconnected nanoskeleton. − Thereinto, the SiO 2 aerogel has shown great application value as a high-efficiency thermal insulation material. , Its 3-dimensionally interconnected nanoporous skeleton can be formed in a sol–gel process, the tortuous pore network has a sufficient number of path terminals to block heat transfer, and the mesoporous size can effectively suppress the convective collision of air molecules . These factors combine to lead to ineffective heat transfer, making the thermal conductivity of the SiO 2 aerogel comparable to or even lower than that of air (0.025 W/(m K)) …”
