Highly Efficient Benzothiophene Capture with a Metal-Modified Copper–1,3,5-Benzenetricarboxylic Acid Adsorbent

To construct more desirable adsorption affinity between the current metal–organic frameworks and benzothiophene (BT), a novel desulfurizer (V/Cu–BTC, where BTC represents 1,3,5-benzenetricarboxylic acid) was prepared by reducing Cu­(II) to Cu­(I) with V­(III) on Cu–BTC using a hydrothermal synthesis method. Using nitrogen adsorption–desorption, powder X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy, we approved that the modifications of those novel desulfurizers have been successfully realized and further compared their structural changes. The BT capture performance from the different simulated fuels with V/Cu–BTC was evaluated by batch tests. The results manifest that V/Cu–BTC exhibited impressive desulfurization capacity, which is grander to Cu–BTC and some other adsorbents reported previously. Additionally, as a result of sieving and inertia mechanisms, this adsorbent possessed an extremely high affinity for BT capture in the presence of benzene. V/Cu–BTC showed a remarkable stability in BT adsorption, maintaining more than 90% initial sulfur uptake capacity after 5 regeneration times. In general, the V/Cu–BTC material is very beneficial for the adsorptive removal of BT

DataSheet_1_Differential responding patterns of the nirK-type and nirS-type denitrifying bacterial communities to an Ulva prolifera green tide in coastal Qingdao areas.docx

Coastal eutrophication may be a vital inducement of green tide. Denitrification is an important nitrogen removal pathway that involves a series of enzymatic reactions. The rate-limiting step in the conversion of nitrite to nitric oxide is encoded by two functionally equivalent but structurally distinct genes, copper-containing nitrite reductase gene (nirK) and cytochrome cd1-containing nitrite reductase gene (nirS). Here, we used Illumina Miseq sequencing approach to examine the variations in denitrifying bacterial community characteristics and interactions during an Ulva prolifera green tide in coastal Qingdao areas. Our findings suggested that the variations in the denitrifying bacterial community structure during the green tide were closely related to the changes of chlorophyll a content, salinity and dissolved oxygen content. The nirK-type denitrifying bacteria were more sensitive to green tide than the nirS-type denitrifying bacteria. Additionally, the nirK-type denitrifying bacterial interactions were more stable and complex during the outbreak phase, while the nirS-type denitrifying bacterial interactions were more stable and complex during the decline phase. All of these characters demonstrated that the nirK-type and nirS-type denitrifying bacteria respond differently to the green tide, implying that they may occupy different niches during the green tide in coastal Qingdao areas.</p
