In situ synthesis of CdS@NH₂-MIL-125 nanocomposite for the enhanced photocatalytic oxidative desulfurization of dibenzothiophene

Abstract

In this work, CdS@NH2-MIL-125 nanocomposite as photocatalyst was successfully synthesized by forming a common boundary between CdS and NH2-MIL-125, via in situ a solvothermal strategy, and then the physicochemical properties...

Amphiphilic Catalysts Comprising Phosphomolybdic Acid Fastened on MIL-101(Cr): Enabling Efficient Oxidative Desulfurization under Solvent-Free and Moderate Reaction Conditions

“…52 The peak at 289.0 eV relates to the carboxyl carbon in the benzene ring, while the peak at 285.7 eV can be imputed to C−N/C�N in the imidazole ring. 53 Additionally, the sp 3 hybridization of C−C in the imidazole long carbon chain may correspond to 286.3 eV. 53 The high-resolution XPS spectrum of O 1s in Figure 5b can be deconvoluted into carboxyl oxygen and O−Mo/O�Mo, which exhibits two well-defined peaks at 531.2 and 530.1 eV.…”

Photoswitchable Catalytic Aerobic Oxidation of Biomass-Based Furfural: A Selective Route for the Synthesis of 5-Hydroxy-2(5H)-furanone and Maleic Acid by Using the CdS/MOF Photocatalyst

“…Recently, we reported the synthesis and full characterization of the CdS@NH 2 -MIL-125 nanocomposite. 44 According to this paper, in the process of the synthesis of the CdS@NH 2 -MIL-125 nanocomposite, first, CdS nanoparticles were synthesized and then NH 2 -MIL-125 was grown on it. The purpose was to encapsulate the CdS nanoparticles inside the holes of the NH 2 -MIL-125.…”

Insights into the sacrificial structure–activity relationship of a Ti-based metal–organic framework in an oxidative desulfurization reaction

“…29 According to previous reports, both pristine and modified MIL-125(Ti) showed moderate catalytic properties in the ODS reaction even at a relatively high reaction temperature. 30–32 Therefore, finding a direct and simple approach for upgrading the ODS activity of pristine MIL-125(Ti) at ambient temperature should be pursued.…”
