The development of cost-effective hydroxide exchange membrane fuel cells is limited by the lack high-performance and low-cost anode hydrogen oxidation reaction catalysts. Here we report a Pt-free catalyst Ru7Ni3/C, which exhibits excellent activity in both rotating disk electrode assembly measurements. mass specific as measured experiments, about 21 25 times that Pt/C, 3 5 PtRu/C, respectively. cell with Ru7Ni3/C can deliver high peak power density 2.03 W cm-2 H2/O2 1.23 H2/air (CO2-free) at...
Social media are acknowledged as an important information source that influences tourists’ travel choices. However, qualitative studies take inductive approach to identify the roles of social by investigating how affect choices limited. By interviewing 21 tourists who had recently taken trips, this article aimed played in six components (destination, transportation, accommodation, food and dining activities, attractions, well shopping leisure activities). Four have been identified: Need...
Abstract Anion-exchange membrane fuel cells and Zn–air batteries based on non-Pt group metal catalysts typically suffer from sluggish cathodic oxygen reduction. Designing advanced catalyst architectures to improve the catalyst’s reduction activity boosting accessible site density by increasing loading utilization are potential ways achieve high device performances. Herein, we report an interfacial assembly strategy binary single-atomic Fe/Co-N x with mass loadings through constructing a...
Metastable phase two-dimensional catalysts provide great flexibility for modifying their chemical, physical, and electronic properties. However, the synthesis of ultrathin metastable metallic nanomaterials is highly challenging, mainly due to anisotropic nature materials thermodynamically unstable ground-state. Here, we report free-standing RhMo nanosheets with atomic thickness a unique core/shell (metastable phase/stable phase) structure. The polymorphic interface between core region shell...
Introducing a second metal species into atomically dispersed metal-nitrogen-carbon (M-N-C) catalysts to construct diatomic sites (DASs) is an effective strategy elevate their activities and stabilities. However, the common pyrolysis-based method usually leads substantial uncertainty for formation of DASs, precise identification resulting DASs also rather difficult. In this regard, we developed two-step specific-adsorption (pyrolysis-free) constructed DAS catalyst featuring FeCo "molecular...
Abstract High-performance platinum-group-metal-free alkaline hydrogen oxidation reaction catalysts are essential for the hydroxide exchange membrane fuel cells, which generally require high Pt loadings on anode. Herein, we report a highly active catalyst, NiCuCr, indicated by cell with peak power density of 577 mW cm −2 (18 times as Ni/C anode) and stability more than 150 h (a degradation rate slower 7 anode). The spectroscopies demonstrate that alloy effect from Cu weakens binding, surface...
To achieve practical application of fuel cell, it is vital to develop highly efficient and durable Pt-free catalysts. Herein, we prepare atomically dispersed ZnNC catalysts with Zn-Pyrrolic-N4 moieties abundant mesoporous structure. The ZnNC-based anion-exchange membrane cell (AEMFC) presents an ultrahigh peak power density 1.63 0.83 W cm-2 in H2 -O2 -air (CO2 -free), also exhibits long-term stability more than 120 100 h for -free) , respectively.

Novel Bi2Te3/graphene quantum dots (Bi2Te3/GQDs) hybrid nanosheets with a unique structure that GQDs are homogeneously embedded in the Bi2Te3 nanosheet matrix have been synthesized by simple solution-based synthesis strategy. A significantly reduced thermal conductivity and enhanced powder factor observed Bi2Te3/GQDs nanosheets, which is ascribed to optimized thermoelectric transport properties of interface. Furthermore, varying size GQDs, performance nanostructures could be further...
Peroxoniobate salts of amidine and guanidine have been utilized as halogen-free catalysts for the synthesis cyclic carbonates from epoxides CO<sub>2</sub> under solvent-free halide-free conditions.
In this work, nitrogen-doped carbon quantum dots from poly(ethyleneimine) (PQDs) were synthesized by a low-cost and facile one-step hydrothermal method without other reagents. A yield (QY) of up to 23.2% with maximum emission at 460 nm under an excitation wavelength 340 was ascribed the high nitrogen doping (20.59%). The PQDs selectively form blue complex Cu2+ accompanied strong quenching fluorescence emission. Meanwhile, PQD-Cu2+ exhibited selective recovery color disappearance on exposure...
Multielemental nanoparticles (MENPs) provide the possibility to integrate multiple catalytic functions from different elements into one nanoparticle. However, it is difficult synthesize Ag-based MENPs with transition metals such as Ni and Fe because of strong phase segregation between Ag other metals. Here, we show that nonmetal element P can help amalgamation Ag–Ni–Fe–P are successfully synthesized by a solution-phase chemistry, they demonstrate excellent bifunctional oxygen reduction...
