Pt nanoparticles encapsulated on V2O5 nanosheets carriers as efficient catalysts for promoted aerobic oxidative desulfurization performance

چکیده
Platinum group metals (PGMs) usually exhibit promising aerobic catalytic abilities, providing a green and feasible oxidative desulfurization method. However, often, the PGM nanoparticles (NPs) get leached, catalysts are deactivated. In this work, Pt NPs with particle sizes of approximately 4–5 nm were encapsulated effectively uniformly on surface vanadium pentoxide (V2O5) nanosheets (with thicknesses six atomic layers) through strong metal-support interactions. The synthesized promote oxidation reactions, realizing deep (99.1%, < 5 ?g g?1) under atmospheric pressure 110 °C reaction temperature. Remarkable degrees sulfur removal could be achieved for oils different initial S-concentrations substrates. Additionally, as-prepared recycled reuse at least seven times.

متن کاملA template-free solvent-mediated synthesis of high surface area boron nitride nanosheets for aerobic oxidative desulfurization.
Hexagonal boron nitride nanosheets (h-BNNs) with rather high specific surface area (SSA) are important two-dimensional layer-structured materials. Here, a solvent-mediated synthesis of h-BNNs revealed a template-free lattice plane control strategy that induced high SSA nanoporous structured h-BNNs with outstanding aerobic oxidative desulfurization performance.
