Modification of cobalt doped mesoporous sieve by grafting N,N-dihydroxypyromellitimide to enhance desulfurization catalyst stability

New Adsorption Materials for Deep Desulfurization of Fuel Oil

“…According to the molecular characteristics of sulfide in oil, some researchers attributed their existing low sulfur adsorption capacity to the influence of adsorbent pore structure, which limited the mass transfer and adsorption properties of thiophene sulfide molecules. Therefore, they began to use mesoporous molecular sieves as the carrier to prepare adsorbent, and a lot of research has been carried out on this topic [63][64][65].…”

Enhancing Cytochrome C Recognition and Adsorption through Epitope-Imprinted Mesoporous Silica with a Tailored Pore Size

“…Several methods are proposed to enlarge the pore size of mesoporous imprinted materials. − Conventional oil-based synthesis systems use a large number of oil phases to achieve an effective swelling effect. In the anion-assisted method, salicylic acid anion (Sal – ) is used to form large pores, and the amount required is significantly reduced, indicating that Sal – has superior micellar penetration compared to the oil phase. , The strong interaction between Sal – and CTA + micelles, including high miscibility and strong electrostatic attraction, drives Sal – to migrate into the micelles, and its hydrophobic part is embedded in the hydrophobic region of the micelles. − Therefore, the anion-assisted method is highly reproducible and the effect of the stirring rate on the particle structure is negligible .…”
