Cobalt nitride enabled benzimidazoles production from furyl/aryl bio-alcohols and -nitroanilines without

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 1,   Pages 68-81 doi: 10.1007/s11705-022-2174-y

Abstract: Benzimidazole derivatives have wide-spectrum biological activities and pharmacological effects, but remain challenging to be produced from biomass feedstocks. Here, we report a green hydrogen transfer strategy for the efficient one-pot production of benzimidazoles from a wide range of bio-alcohols and o-nitroanilines enabled by cobalt nitride species on hierarchically porous and recyclable nitrogen-doped carbon catalysts (Co/CNx-T, T denotes the pyrolysis temperature) without using an external hydrogen source and base additive. Among the tested catalysts, Co/CNx-700 exhibited superior catalytic performance, furnishing 2-substituted benzimidazoles in 65%–92% yields. Detailed mechanistic studies manifest that the coordination between Co2+ and N with appropriate electronic state on the porous nitrogen-doped carbon having structural defects, as well as the remarkable synergetic effect of Co/N dual sites contribute to the pronounced activity of Co/CNx-700, while too high pyrolysis temperature may cause the breakage of the catalyst Co–N bond to lower down its activity. Also, it is revealed that the initial dehydrogenation of bio-alcohol and the subsequent cyclodehydrogenation are closely correlated with the hydrogenation of nitro groups. The catalytic hydrogen transfer-coupling protocol opens a new avenue for the synthesis of N-heterocyclic compounds from biomass.

Effect of electrokinetic property of charged polyether sulfone membrane on bovine serum albumin fouling

Xiaorong Meng, Shanshan Huo, Lei Wang, Xudong Wang, Yongtao Lv, Weiting Tang, Rui Miao, Danxi Huang

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 2, doi: 10.1007/s11783-017-0907-9

Abstract: Negatively charged CMPES and positively charged QAPES membranes were fabricated. Charge modification reduced the adhesion forces between PES UF membranes and BSA. QAPES-BSA / was weaker than that of CMPES-BSA at pH 3 and on the contrary at pH 9. Flux decline rate was positively correlated with the adhesion forces of membrane-BSA. Variation of adhesion was consistent with that of potential absolute values. Negatively charged carboxymethylated polyethersulfone (CMPES) and positively charged quaternized polyethersulfone (QAPES) ultrafiltration (UF) membranes were prepared by bulk chemical modification and non-solvent induced phase separation method. The effects of PES membrane interfacial electrokinetic property on the bovine serum albumin (BSA) membrane fouling behavior were studied with the aid of the membrane-modified colloidal atomic force microscopy (AFM) probe. Electrokinetic test results indicated that the streaming potential (D ) of QAPES membrane was not consistent with its expected value, however, within the pH range of 3–10, the potentials of two charged-modified PES membranes were more stable than the unmodified membrane. When pH value was 3, 4.7 or 9, the interaction behavior between charged PES membrane and BSA showed that there was significant linear correlation between the jump distance of membrane-BSA adhesion force ( ) and the potential absolute value. Charged modification significantly reduced the adhesion of PES membrane-BSA, and the adhesion data was good linear correlated with the flux decline rate in BSA filtration process, especially reflected in the CMPES membrane. The above experimental facts proved that the charged membrane interfacial electric double layer structure and its electrokinetic property had strong ties with the protein membrane fouling behavior.
