“…[36] The corelevel signal of N 1s validates the N functionalities of graphitic N (400.2 eV), pyrrolic N (399.4 eV), and pyridinic N (397.9 eV) ( Figure S3c, Supporting Information). The characteristic peak of S 2− related to metal sulfide is not observed in [37,38] Similarly, the Ni 2p spectrum ( Figure 4d) consists of two doublets corresponding to Ni 2p 3/2 and Ni 2p 1/2 , where the strong peaks (855.8 and 873.4 eV) are assigned to metallic Ni 0 and the weak peaks (861.6 and 879.5 eV) designate the oxidized form of Ni 2+ . The characteristic peaks at 161.9 and 167.6 eV designate the existence of SH and oxidic sulfur (CSO x ) species.…”

“…[36] The S 2p spectrum ( Figure S3d, Supporting Information) demonstrates significant peaks, ascribed to S 2p 3/2 (163.4 eV) and S 2p 1/2 (164.5 eV), implying that the sulfur atoms are incorporated into the carbon lattice structure in the form of CSC covalent bond and CS. [38] The subsistence of Pd 2+ and Ni 2+ species can be attributed to the formation of metal oxides via the partial surface oxidation of unreacted metallic Pd and Ni in air. [36] The presence of CN/CS species ensures that the N (6.4%) and S (3.9%) heteroatoms are effectively doped into the carbon lattice of the aerogel fibers.…”

as biological renewability, low toxicity, and easy storability. [5] Despite the recent improvements in DEGFCs, the technology is still hindered by the problems of conventional platinum (Pt) anode catalysts, such as surface poisoning, high cost, and scarcity. [6] Recently, palladium (Pd) nanostructures have emerged as a promising EG oxidation catalyst in alkaline media, eliminating the necessity of the Pt nanocatalyst for EG oxidation. [7] However, Pd nanocatalysts are prone to rapid deterioration under surface poisoning and instability. [8] The formation of bimetals with non-precious transition metals (PdM, M = Ni, Co, Fe, Cu, Mo, Sn, etc.) is an efficient strategy to improve the stability without sacrificing the catalytic activity. [9] The oxophilic nickel (Ni) is recognized as a naturally abundant metal with enhanced corrosion resistance. [10] The inclusion of Ni into the crystal lattice of Pd facilitates active sites for -OH adsorption (OH ads ) and weakens their interaction with reaction intermediates adsorbed onto the Pd surface. [10,11] In parallel, metal nanoparticles decorated on carbon supports have also been shown to improve EG oxidation via their high electrical conductivity and catalytic activity. [12] The 3D porous structure of carbon nanotubes (CNTs) could considerably control the aggregation or stacking of the adjacent subunits, facilitating a uniform distribution of metal nanoparticles and increasing the number of accessible reactive sites for catalytic surface reactions. [13] However, the conventional strategy used for the fabrication of metal nanoparticles anchored onto CNTs involves strenuous multistep procedures, and the acidification process involved distorts the interconnected conduction channels, which consequently limits the EG oxidation kinetics. [14] Hence, the development of catalytically active metal nanoparticles encased within the graphitic layers of CNTs is highly desirable. [15] The mass transfer capability and catalytic activity of carbon nanostructures could be further improved with the development of porosity and heteroatom doping into the carbon skeleton. [16] Recently, 3D carbon aerogels (CAs) have grasped prevailing research attention as free-standing electrodes for diverse energy applications owing to their large specific surface area, low density, interconnected fibrous structure, and rapid charge transport pathways. [17,18] In this context, Pd nanoparticles Flexible and 3D carbon aerogels (CAs) composed of carbon nanotubes (CNTs) with carbon shell-confined binary palladium-nickel (Pd x -Ni y ) nanocatalysts on carbon fibers (Pd x -Ni y /NSCNT/CA) have been developed through a facile chemical vapor deposition method. The 3D porous carbon network and the synergistic effect of carbon shell-confined bimetal nanoparticles of rationally constructed aerogels facilitate enhanced electrocatalytic and antipoisoning activities toward ethylene glycol (EG) oxidation reaction compared to the commercial Pt/C catalyst. With the 3D morphological features and direct growth of Pd-Ni bimet...

“…Monometallic Pd/MCN NCs exhibit excellent catalytic properties (Figure a) with 3 equiv H 2 per NH 3 BH 3 released within 0.8 min. The total turnover frequency (TOF) for Pd/MCN NCs reaches 125 min −1 , which is among the highest values of the monometallic Pd‐based catalysts reported to date (Table ) . However, monometallic Ni/MCN NCs exhibit a limited catalytic activity with only 2.2 equiv H 2 per NH 3 BH 3 released in 50 min.…”

Highly dispersed Pd and PdNi nanoparticles (NPs) have been successfully immobilized on mesoporous carbon nitride (MCN) through a facile co‐reduction approach. The resulting Pd/MCN catalyst shows excellent catalytic performance for hydrogen release from an ammonia borane (AB) aqueous solution with a turnover frequency (TOF) value of 125 mol H2 mol metal−1 min−1 at room temperature, which is among the highest values for monometallic Pd‐based catalysts reported to date. The catalytic performance of the Pd NPs can be further enhanced by alloying with Ni or Co atoms. Among all the synthesized PdxNi100−x/MCN nanocomposites (NCs) with different Ni/Pd ratios, the Pd74Ni26/MCN catalyst exhibits the best catalytic performance with a TOF of 246.8 mol H2 mol metal−1 min−1. The high activity of Pd/MCN and Pd74Ni26/MCN are largely dependent on the features of the ultrafine metallic NPs immobilized by MCN, the interfacial interaction between the MCN matrix and metallic NPs, and the accessible open porous structure for mass transfer.

“…Noble metal-based catalysts, especially, are an interesting alternative which is attributed to their unique high activity under mild reaction conditions (Wang et al 2016;Valles et al 2016;Zhang et al 2016). The cost of using a noble metal-based catalyst such as Rh, Pt, Ir and Pd can be compensated by using low temperatures and H 2 pressures (Valles et al 2016).…”

Bimetallic magnetic PtPd-nanoparticles as efficient catalyst for PAH removal from liquid media

et al. 2017

Monometallic Pd-and bimetallic PtPd-nanoparticles supported on a mesoporous magnetic magnetite@silica matrix resembling a core-shell structure (Fe 3 O 4 @mSiO 2 ) have been fabricated. The material was characterized by transmission electron microscope (TEM), high-angle annular dark field-scanning transmission electron microscopy (HAADF-STEM), X-ray photoelectron spectra (XPS), energy dispersive spectroscopy (EDS) and inductively coupled plasma mass spectrometry (ICP-MS). The catalysts were applied in the removal of anthracene from liquid phase via catalytic hydrogenation. It was found that anthracene as a model compound could be completely converted into the partially hydrogenated species by the monometallic and bimetallic solids. However, during the recycling study the bimetallic material (Fe 3 O 4 @mSiO 2-PtPd-) showed an enhanced activity towards anthracene removal compared with the monometallic materials. A single portion of the PtPd-based catalyst can be used up to 11 times in the hydrogenation of anthracene under mild conditions (6 atm of H 2 , 75°C, 20 min). Thanks to the presence of a dense magnetic core, the catalysts were capable of responding to an applied external magnetic field and once the reaction was completed, catalyst/product separation was straightforward.
