“…The tetrahedral sheet was continuous across the ribbons but with apices pointing up and down in adjacent ribbon [22]. These silica tetrahedral ribbons had abundant Si–OH groups, which could adsorb and hold the cations such as Fe 3+ , Ni 2+ ions [19, 39] and SbO + ions as well. Secondly, the complex dissociation equilibrium of antimony tartrate complex ions was shown as Eq.…”

“…One of the most widely used as supporting materials for the surface modification is clay mineral. The composites by introducing of clay mineral [10–12], such as kaolinite [13, 14], halloysite [15, 16], montmorillonite [17], and sepiolite [18], do not only enhance the dispersion of nanoparticles but also improve the gather of reactants which would produce synergetic effect in the catalytic process and further intensify its catalytic performance [19]. Moreover, the cost of clay mineral is lower than the metal catalyst, which would further reduce the costs of catalysts and facilitate its practical application.…”

“…Palygorskite (PAL), a species of natural clay mineral with theory formula (Mg,Al,Fe) 5 Si 8 O 20 (OH) 2 (OH 2 ) 4 ·4H 2 O has been widely applied due to its particular fiber-liked morphology [20–22] which endowed unique properties, such as larger surface area [23], nontoxicity [24], and excellent adsorption capacity [25]. Owing to such particular properties, PAL is used as adsorbents [26, 27], catalysts, and catalyst supports [19]. For example, the modified PAL shows superior adsorption capacities than raw PAL [28, 29].…”

A Sb/palygorskite (PAL) composite was synthesized by a facile solvothermal process and applied in catalytic hydrogenation of p-nitrophenol for the first time. It was found that the Sb nanoparticles with the sizes of 2–5 nm were well dispersed on the fiber of PAL, while partial aggregated Sb nanoparticles with sizes smaller than 200 nm were also loaded on the PAL. The Sb/PAL composite with 9.7% Sb mass amounts showed outstanding catalytic performance by raising the p-nitrophenol conversion rate to 88.3% within 5 min, which was attributed to the synergistical effect of Sb and PAL nanoparticles facilitating the adsorption and catalytic hydrogenation of p-nitrophenol.Electronic supplementary materialThe online version of this article (doi:10.1186/s11671-017-2220-8) contains supplementary material, which is available to authorized users.

“…4) of Ni/MPSCMFA correspond to Ni 2p1/2 and the three principal peaks in the range of 851-861 eV are attributed to Ni 2p3/2. The peaks at 872.4 and 853.6, 852.8, 856.4, and 861.5 eV are assigned to Ni 2+ in NiO particles (Ni\O bonds), the chemical bonds of metallic nickel, a higher hydroxylation of NiO on the support surface, and the satellite peak for NiO [23,24], respectively. These results indicate that supported NNPs partially interact with MPSCMFA, which is in agreement with the result given in Fig.…”

Simultaneously enhancing strength and toughness through simple and low‐cost methods has always been a challenge for polylactic acid (PLA) materials. In this context, natural attapulgite (ATT) nanorods were used as fillers combined with fused deposition modeling (FDM) to improve the strength and toughness of PLA. The printable PLA nanocomposite filaments filled with ATT nanorods were prepared by melting compounding and smoothly printed via a commercial FDM three‐dimensional (3D) printer. The influences of FDM process and ATT filling on the properties of PLA/ATT composite parts were evaluated through microstructure analysis, rheological, and mechanical tests. The results suggest that PLA/ATT composite parts manufactured by FDM exhibit superior mechanical properties, which can be attributed to the FDM induced orientation and nucleation effect of ATT nanorods. The tensile strength can reach 56 MPa with the addition of 2 wt% ATT at a nozzle temperature of 205°C, increasing by 24% compared to pure PLA. In addition, the fracture elongation of PLA/ATT parts printed by FDM has significantly increased to 26%, which is 924% higher than pure PLA. Furthermore, the filling of ATT significantly improves the storage modulus of composite parts. This work provides a new high‐strength, ultra tough, low‐cost, and printing stable PLA/ATT composite material and forming method, offering a promising avenue for the wider application of PLA and ATT in the future.
