“…While the similar current density for 20 wt% Pt/C suggested a significant decrease from 1590 to 749 mA cm −2 during 16 h under the same operating conditions. The high durability of Ru–Ru 2 PΦNPC might be due to the Ru–Ru 2 P embedded into NPC matrix to establish the unique semiwrapped structure (Figure d), which not only exposed abundant of active sites but also effectively prevented the active substances from corrosion, fall off, and aggregation during i – t testing . In addition, the amount of hydrogen generated in the cathode was authenticated to be H 2 by gas chromatography, and the corresponding hydrogen production rate was 15.4 µmol mg −1 min −1 (Figure S24, Supporting Information).…”

Although numerous ruthenium-based phosphates possess high catalytic activities for hydrogen evolution reaction (HER), most of them rely on dangerous and toxic synthesis routes. Biological slices confirm that Ru ions can penetrate the cell walls of saccharomycete, which facilitates the adsorption of Ru ions. Herein, based on a green synthesis process by saccharomycete cells as the carbon template and nitrogen/phosphorus (N/P) sources, novel Janus-like rutheniumruthenium phosphide nanoparticles embedded into a N/P dual-doped carbon matrix (Ru-Ru 2 PΦNPC) electrocatalyst for HER are synthesized. Electrochemical tests reveal that Ru-Ru 2 PΦNPC displays remarkable performance with a low overpotential of 42 mV at 10 mA cm −2 and demonstrates superior stability at a high current density in 0.5 m H 2 SO 4 . Furthermore, ruthenium oxide nanoparticles coated N/P dual-doped carbon (NPC@RuO 2 ) are also synthesized with a yolk-shell structure using saccharomycete cells as the core template and RuO 2 as a shell to isolate saccharomycete cells from the oxidation reaction during calcination in air. The NPC@RuO 2 as oxygen evolution reaction electrocatalyst possesses a low overpotential of 220 mV at 10 mA cm −2 . Finally, the Ru-Ru 2 PΦNPC is integrated as a cathode and NPC@RuO 2 is integrated as an anode to construct a two-electrode electrolyzer to enable an excellent performance for overall water splitting with a cell voltage of 1.50 V at 10 mA cm −2 in 0.5 m H 2 SO 4 .

“…It can be seen that 96% of the initial current density was retained for NCNi/SWCNT-700 after 24 h, while only 72% was retained for the Pt/C-Ir/C. [39,[48][49][50] The excellent electrocatalytic performance of NCNi/SWCNT-700 can be attributed to the synergetic effect of small Ni particles, monolayer N-doped carbon cover, and high-quality N-doped SWCNTs (Figure 2b).

Noble‐metal free, cost‐effective, and highly stable catalysts with efficient activity for both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) have attracted tremendous research interest in recent years. Here, a flexible, self‐standing hybrid film comprising a N‐doped single‐wall carbon nanotube (SWCNT) network on which are anchored Ni nanoparticles encapsulated by a monolayer of N‐doped carbon (NCNi) is reported. The films are prepared by floating catalyst chemical vapor deposition followed by NH 3 treatment. The material obtained at optimum conditions shows excellent bifunctional electrocatalytic activity in alkaline media with low overpotentials of 190 and 270 mV for HER and OER, respectively, to reach a current density of 10 mA cm −2 . A current density of 10 mA cm −2 at 1.57 V is achieved when this freestanding and binder‐free rod‐shaped NCNi/SWCNT assembly is used as cathode and anode in 1 m KOH solution for overall water splitting, presenting one of the best values reported to date.

“…The cost of carbon fiber cloth has been greatly reduced due to the improvement of carbon fiber preparation technology. Since carbon fiber cloth has the characteristics of low resistance and good durability, it has been studied in the preparation of electrodes [24] and in 3D printing heating materials [25]. Furthermore, the mechanical strength of carbon fiber cloth is high.…”

To reduce the impact of road ice and snow disaster, it is necessary to adopt low energy consumption and efficient active deicing and snow melting methods. In this article, three functional components are combined into a conductive ethylene propylene diene monomer (EPDM) rubber composite material with good interface bonding. Among them, the mechanical and electrical properties of the composite material are enhanced by using carbon fiber cloth as a heating layer. EPDM rubber plays a mainly protective role. Further, aluminum silicate fiber cloth is used as a thermal insulation layer. The mechanical properties of EPDM rubber composites reinforced by carbon fiber cloth and the thermal behaviors of the composite material in high and low temperature environments were studied. The heat generation and heat transfer effect of the composite were analyzed by electrothermal tests. The results show that the conductive EPDM rubber composite material has good temperature durability, outstanding mechanical stability, and excellent heat production capacity. The feasibility of the material for road active deicing and snow melting is verified. It is a kind of electric heating deicing material with broad application prospects.
