“…In addition, Ni could change the electronic structure of Pd and thus modulate the catalytic performance of the Ni-Pd/Fe 3 O 4 catalyst [46,47]. It is worth noting that the catalytic activity of the Ni-Pd/Fe 3 O 4 catalyst surpassed many of the Fe 3 O 4 -supported nanocatalysts reported within recent five years (Figure 7a and Table S1) [35,[48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65][66]. In addition, the magnetic recyclability and durability were studied by repeating the catalytic reduction of 4-NP the presence of a recycled Ni-Pd/Fe 3 O 4 catalyst.…”

The use of metal-based heterogeneous catalysts for the degradation of N-containing organic dyes has attracted much attention due to their excellent treatment efficiency and capability. Here, we report the synthesis of heterometals (Ni and Pd)-incorporated Fe3O4 (Ni-Pd/Fe3O4) yolk-shelled nanospheres for the catalytic reduction of N-containing organic dyes using a facile combination of solvothermal treatment and high-temperature annealing steps. Benefiting from the magnetic properties and the yolk-shelled structure of the Fe3O4 support, as well as the uniformly dispersed active heterometals incorporated in the shell and yolk of spherical Fe3O4 nanoparticles, the as-prepared Ni-Pd/Fe3O4 composite shows excellent recyclability and enhanced catalytic activity for three N-containing organic dyes (e.g., 4-nitrophenol, Congo red, and methyl orange) compared with its mono metal counterparts (e.g., Ni/Fe3O4 and Pd/Fe3O4). In the 4-nitrophenol reduction reaction, the catalytic activity of Ni-Pd/Fe3O4 was superior to many Fe3O4-supported nanocatalysts reported within the last five years. This work provides an effective strategy to boost the activity of iron oxide-based catalytic materials via dual or even multiple heterometallic incorporation strategy and sheds new light on environmental catalysis.

“…At present, as far as we know, the fabrication of the metal implanted oxide aerogels is mainly based on multiple-step methods (including the organic template method, the sol-gel method, and the hydrothermal method) [13][14][15][16][17][18][19] and usually needs the pre-preparation of the aerogel networks and subsequent introduction of noble metals. The introduction of noble metal NPs is usually realized via physical or chemical deposition.…”

“…The introduction of noble metal NPs is usually realized via physical or chemical deposition. For example, Lo et al achieved Ag NP implanted Fe 3 O 4 aerogels via photo-depositing of Ag NPs from silver nitrate solution into sol-gel method-produced Fe 3 O 4 aerogels [19]. However, the current methods mostly suffer from long fabrication periods (generally, more than 1 day), complex equipment, and tedious steps.…”

Simple fabrication of metal-modified oxide aerogels is expected but remains challenging. This work presents a sample one-pot synthesis method for gold nanoparticle (NP) implanted ZnO (Au-ZnO) aerogels just by sequentially adding (CH3COO)2Zn and NaBH4 solutions into a pre-prepared Au colloidal solution. The typically fabricated Au-ZnO aerogels are constituted by ZnO networks implanted with uniform Au NPs. The Au NPs had a size of about 100 nm, and the ZnO nanochains in the networks were about 10 nm in thickness. Further, the proportion of the Au NPs in the final aerogels could be tuned by using different amounts of the Zn precursors. Furthermore, a mechanism based on metal oxidation and oriented connection growth (a self-organization process) has been presented for describing the formation of such Au-ZnO aerogels. In the typical formation, the Zn2+ ions first convert into ZnO beads, and then are self-organized to form networks wrapping the colloidal Au NPs under the effect of linker molecules, and this matches well with the observed experimental results. Most importantly, these Au-ZnO aerogels show great structurally enhanced gas sensing properties to gaseous ethanol compared with a pure ZnO film. They have a fast response (about 30 s), a high selectivity, and quantitative sensing to the target gas. This work has provided a simple preparation method for Au-ZnO aerogels, and also shows their great potential in gas sensing applications.
