Boosting aerobic oxidative desulfurization performance in fuel oil via strong metal-edge interactions between Pt and h-BN

Platinum nanoparticles (Pt NPs) have long been regarded as efficient catalysts for numerous catalytic process, including catalytic oxidation, hydrogenation, etc. For Pt catalysis, tuning the electronic structure for a boosted catalytic performance and exploring a proper strategy for stabilization of the nanoparticles are the two central issues. In this work, we constructed strong metal-edge interactions (SMEI) between well-dispersed Pt NPs and hexagonal boron nitride (h-BN) support. The charge transfer between h-BN and Pt NPs was carefully studied, and it was found that the charge transfers from B atoms in h-BN to Pt NPs and from Pt NPs to N atoms in h-BN. The SMEI makes the Pt NPs positively charged for a boosted aerobic catalytic desulfurization activity with sulfur removals of 98.3%, 96.5%, 93.7% and 85.9% to dibenzothiophene, 4, 6-dimethyldibenzothiophene, 4-methylbenzothiophene, and benzothiophene, respectively. Additionally, the aerobic oxidative desulfurization system showed an excellent resistance performance to olefins and aromatic hydrocarbons. The SMEI also gives rise to an excellent stabilization of the Pt NPs without agglomeration after the reaction. Moreover, the catalyst can be recycled 5 times without a significant decrease in catalytic activity. Additionally, both the geometric structure and the SMEI were well investigated to illuminate the structure-activity relationship.

Application of toxicity-based fractionation techniques and structure- activity relationship models for the identification of phototoxic polycyclic aromatic hydrocarbons in sediment pore water

Recent studies conducted at our laboratory have shown that sediments contaminated with complex mixtures of polycyclic aromatic hydrocarbons (PAHs) can exhibit enhanced toxicity (lethality) to a variety of aquatic species when the samples are tested under ultraviolet (UV) light designed to mimic the wavelengths present in sunlight. However, because these contaminated sediments can contain literally thousands of chemicals, it is difficult to use conventional analytical techniques to identify those compounds responsible for photo-induced toxicity. The purpose of this study was to adapt existing toxicity identification evaluation methods to attempt to identify those compounds contributing to the phototoxicity observed in our sediment samples. Pore water obtained from sediments collected near an oil refinery discharge was toxic to Lumbriculus variegatus following exposure to UV light, while organisms exposed to the same pore water, but without subsequent UV treatment, showed no toxic effect. Solid-phase extraction disks and high-performance liquid chromatography were used, in conjunction with toxicity tests with L. variegatus, to extract and fractionate phototoxic chemicals from the pore water. Phototoxic fractions analyzed by gas chromatography-mass spectrometry revealed the presence of a number of aliphatic hydrocarbons, substituted PAHs, and PAHs containing heteroatoms. Chemicals were screened for their phototoxic potential based on empirical data and predictive models. A refined list of PAHs was then evaluated on the basis of their phototoxic potency as defined by a recently developed quantitative structure-activity relationship model and estimates of their bioaccumulation potential. Based on the model predictions of potency and bioaccumulation, nine likely phototoxic chemicals were identified.

Detectors and basic data analysis

This chapter is focused on the combination of comprehensive two-dimensional gas chromatography (GC¡ÁGC) with ?information-poor? (at different levels) forms of detection, such as flame ionization detection, electron capture detection, etc., and with ?information-rich? ones, namely mass spectrometry (MS) in its various forms and vacuum ultraviolet detection. Apart from basic principles related to the different forms of detection, several examples highlighting the power and opportunities, in particular of the three-dimensional technology GC¡ÁGC-MS, will be illustrated and discussed. Basic details on data analysis are also given.

HIGH-TEMPERATURE ORGANIC SYNTHESIS. XLII. REACTION OF HALOGENOARENES AND 2-CHLOROTHIOPHENE WITH HYDROGEN SULFIDE IN THE PRESENCE OF ACETYLENE

Benzothiophenes are formed with yields of more than 77percent in a single preparative stage during the gas-phase reaction of halogenoarenes with hydrogen sulfide and acetylene (600-700 deg C).It is suggested that arylthiyl radicals (ArS-radical), which are effectively captured by the acetylene, participate in the process.The effect of the structure of the halogenoarene on the selectivity of the process is discussed.The gas-phase reaction of 2-chlorothiophene with hydrogen sulfide in the presence of acetylene leads to the formation of thieno<2,3-b>thiophene.
