Highly dispersed Ag clusters for active and stable hydrogen peroxide production

High-efficiency electrocatalytic NO reduction to NH3by nanoporous VN

“…1(b)). Meanwhile, it should be noted that partial N has been doped into carbon fiber cloth, which contributes a high conductivity and thus favors the charge transfer [30,42].…”

Bifunctional BiPd Alloy Particles Anchored on Carbon Matrix for Reversible Zn–CO2 Battery

“…The FAO performance of BiPdC and tolerance of catalysts were evaluated by cyclic voltammetry (CV) and chronoamperometric curves (Figure c,d). − Compared with BiC catalyst, BiPdC and 2BiPdC exhibit distinct oxidation peaks for FAO at 6.2 and 5.4 mA cm –2 current density, respectively (Figure c). Similarly, prolonged chronoamperometric curves have demonstrated that the current density of BiPdC and 2BiPdC was reduced to 4.26 mA cm –2 (14.40% of its original value) and 0.63 mA cm –2 (7.49% of its original value), respectively, and becomes stabilized after 10 h under optimal FAO potential (Figure d).…”

Cu2O-Derived PtCu Nanoalloy toward Energy-Efficient Hydrogen Production via Hydrazine Electrolysis under Large Current Density

“…The corresponding Tafel plots were calculated and displayed in Figure b. The PtCu-NA has a Tafel slope of 40 mV dec –1 , which is smaller than those of Pt/C (112 mV dec –1 ) and PtCu–Cl (82 mV dec –1 ), indicating that the PtCu-NA also has a favorable reaction kinetics for HzOR. − Thus, at current density of 200 mA cm –2 , the PtCu-NA only needs an overpotential of 668 mV, which is much smaller than that of Pt/C (1081 mV). Additionally, the PtCu-NA delivered a rather flat response over 50 h at 10 mA cm –2 , thus proving its performance stability.…”
