“…The FC3R contained different crystalline zeolite phases (mainly Y zeolite and ZSM-5 zeolite) and Al 2 O 3 , which were identified well through XRD. 27 The diffraction peaks of the activated FC3R sample showed a higher intensity at 2θ = 10.27, 12.07, 15.87, and 24.00°, which indicated the higher crystallinity of the Y zeolite present in the FC3R. This result was attributed to the residues on the surface of FC3R, which were removed (this result was consistent with SEM–EDS ( Table 1 )).…”

A PEG1000-modified nickel-based catalyst (Ni-PEG1000/FC3R) supported on an activated fluid catalytic cracking catalyst residue (FC3R) was synthesized and applied to C9 petroleum resin (C9PR) hydrogenation. The results of the Brunauer–Emmett–Teller method, X-ray diffraction, H 2 temperature-programmed reduction, and scanning electron microscopy–energy-dispersive X-ray spectroscopy show that the Ni-PEG1000/FC3R catalyst had a smaller crystallite size and higher Ni dispersion than those of a Ni/FC3R catalyst. The prepared Ni-PEG1000/FC3R catalyst was applied in a hydrogenation of C9PR at 270 °C and 6 MPa H 2 pressure for 3 h. Under these conditions, the bromine value of C9PR was decreased from 46.1 g Br/100 g (Gardner color grade no. 11) to 0.72 g Br/100 g (Gardner color grade no. 1), and the sulfur content was reduced from 25.7 to 1.66 mg kg –1 . Experimental results show that the Ni-PEG1000/FC3R catalyst exhibited high activity and stability for C9PR hydrogenation.

“…The catalytic hydrogenation reaction of 4-NP to 4-aminophenol (4-AP) was performed at room temperature and pressure, in accordance with previous literature. 19 The 2 mg of Pd/rGO, Ag/rGO, and Pd-Ag/rGO nanocomposites were added into 50 mL of 4-NP aqueous solution (0.12 mmol L −1 ), respectively. Then, 2.5 mL of fresh NaBH 4 solution (0.1 mol L −1 ) was added into the solutions to start the reaction.…”

BACKGROUND Graphene‐supported nanocomposites are promising catalysts for their unique properties. Biosynthesis of such hybrid catalysts possesses several advantages over other methods such as less pollution. The palladium nanoparticle has versatile catalytic activities and its stability and activities can be significantly improved through hybridization with other nanomaterials including graphene. RESULTS In this study, bimetallic palladium‐silver nanoparticles supported on graphene (Pd‐Ag/rGO) was prepared through one‐step biosynthesis using a bacterium Shewanella oneidensis MR‐1. Shewanella oneidensis MR‐1 synthesized Pd‐Ag/rGO through simultaneous reduction of silver nitrate (AgNO3), palladium(II) nitrate (Pd(NO3)2) and graphene oxide (GO). The morphology and composition of the Pd‐Ag/rGO were characterized by transmission electron microscopy, energy dispersive X‐ray, X‐ray diffraction, X‐ray photoelectron spectroscopy, Fourier‐transform infrared spectroscopy and Raman spectroscopy. Furthermore, the hydrogenation activity of synthesized Pd‐Ag/rGO was tested using 4‐nitrophenol as a model chemical at room temperatures and pressure. The Pd‐Ag/rGO showed the best catalytic performance when Pd/Ag ratio was 1:1 and bacterial concentration was 1.0 of OD600 (optical density measured at a wavelength of 600 nm) for the preparation of Pd‐Ag/rGO. Therefore, the kinetic rate constant for 4‐NP reduction was 0.2413 min−1 catalyzed by as‐prepared Pd‐Ag/rGO, which is listed as one of the top level reported catalysts for 4‐NP reduction. CONCLUSION Therefore, this study demonstrated a material and energy‐saving method to synthesize hybrid nanoparticles supported on graphene with high catalytic activity. © 2019 Society of Chemical Industry

Novel polyvinylidene fluoride/TiO2/UiO-66-NH2 (PVDF/TiUN) membranes were produced by the delay phase separation method via introducing the TiO2/UiO-66-NH2 (TiUN) nanocomposite into PVDF casting solution. Interconnection of TiO2 and UiO-66-NH2 improved photocatalysis capacity and endowed PVDF/TiUN membranes with self-cleaning capability. Quantitative measurements showed that, firstly, PVDF/TiUN membranes exhibited improved photodegradation kinetics and efficiency (up to 88.1%) to Rhodamine B (RhB). Secondly, the performances of bovine serum albumin (BSA) rejection and permeation of PVDF/TiUN membranes outperformed those of other check samples, indicating enhanced hydrophilicity. Thirdly, rejection rate of BSA reached to breathtaking 98.14% and flux recovery ratio (FRR) of BSA reached breathtaking 95.37%. Thus, given their excellent anti-contamination property and separation performance, the PVDF/TiUN membrane is very likely to be a novel water treatment membrane.
