Microfluidic fuel cells as paper-based power sources in a standard lateral flow test format.
Pt and Au are not miscible within a whole range of concentrations. To obtain PtAu alloys, severe thermal treatments required that to provide aggregation phenomena. However, it is possible synthesize bimetallic nanoparticles provided the proper synthesis route employed. When they prepared from water-in-oil microemulsions or with impregnation technique, nanosized particles. In contrast, other colloidal routes have been seen be adequate for Pt-based particles, affording segregated samples Pt-...
This work reports a family of Ru-based perovskites for acid OER. Dy 2 NiRuO 6 displays the highest activity and stability more than 400 OER cycles. Its high is related to short Ru–O bonds surface local ratio Ni : Ru close 1 1.
In the present work, methanol oxidation reaction was investigated on Pt particles of various diameters carbon-nanofibers and carbon-black supports with different surface-oxygen concentrations, aiming for a better understanding relationship between catalyst properties electrochemical performance. The pre-synthesized nanoparticles in ethylene glycol, prepared by polyol method without using any capping agents, were deposited carbon supports. Removal oxygen-groups from had profound positive...
The demand of green hydrogen, that is, the hydrogen produced from water electrolysis, is expected to increase dramatically in coming years. State‐of‐the‐art proton exchange membrane electrolysis (PEMWE) uses high loadings platinum group metals, such as Pt electrode where produced. Alternative electrodes based on phosphides, sulfides, nitrides, and other low‐cost alternatives are under investigation. Herein, a simple process for preparation RuP with activity evolution reaction (HER) acidic...
A mixed oxide with the crystal structure of DyMn2O5 family, namely NdMn1.5Ru0.5O5, is reported active for oxygen evolution reaction (OER) in acidic media. NdMn1.5Ru0.5O5 displays high OER activity 500 gRu−1 at 1.5 V. Moreover, more stable than most Ru oxides to date, remaining cycles between 1.1. and 1.7 V low scan rate 10 mV s−1. The stability are attributed cations, as NdMn2O5 exhibits very activity. has particularly short Ru–Ru distances 2.60 Å, a value close metallic around 2.642 Å....
The stability of different types platinum surfaces in the presence chloride was evaluated by applying a potential 1.2 V vs reversible hydrogen electrode while associated mass change Pt monitored with an electrochemical quartz crystal microbalance. metal based on particles and films show large difference toward dissolution when exposed to small amounts chloride. While electrodeposited film showed no degradation sulfuric acid solution containing 10 ppm chloride, made from fuel cell catalyst...
Abstract Monodispersed Pt 3 Sn nanoparticles were prepared through a mild thermal synthesis in the presence of surfactants. The performance for electrooxidation ethanol and adsorbed carbon monoxide (CO ad ) acid medium was studied by combination electrochemical situ spectroscopic methods, namely, infrared reflection absorption spectroscopy differential mass spectrometry (DEMS), results compared to those obtained with use black. formation solid solution promoted oxidation CO at less‐positive...
