The half-wave potential in 0.5 M H2SO4 solution was as high as 0.91 V, and the electrochemically active surface area was up to 95.3 m2 g−1. Show moreView article Noble-metal-free electrospun nanomaterials as electrocatalysts for oxygen reduction reaction Zhaoquan Xu, ... ...
32)54,55. For the bienzymatic reaction system a reaction temperature of 30 °C and a pH value of 7.5 were found to enable up to 96% conversion (Supplementary Table 7, entry 12). Attempts to further increase the substrate loading to 50 or 100 mM resulted in somewhat reduced ...
Single-atom Fe-N-C catalysts has attracted widespread attentions in the oxygen reduction reaction (ORR). However, the origin of ORR activity on Fe-N-C catalysts is still unclear, which hinder the further improvement of Fe-N-C catalysts. Herein, we provide a model to understand the ORR acti...
The data contained in Table I and graphically displayed in FIG. 5 show that an increase in reaction temperature results in a corresponding increase in silicon carbide crystal size as well as a decrease in BET surface area. This suggests that ultimate silicon carbide crystal size and size distribu...
Oxygen reduction reaction in Pr2NiO4+delta/Ce0.9Gd0.1O1.95 and La0.6Sr0.4Co0.2Fe0.8O3-delta/La0.8Sr0.2Ga0.8Mg0.2O2.80 half cells: an electrochemical study The electrochemical properties of La0.6Sr0.4Co0.2Fe0.8O3-delta and Pr2NiO4+delta electrodes screen-printed on La0.8Sr0.2Ga0.8Mg0.2O2.8...
The unique rough-surfaced multicubic structure with ample active edge, corner and step atoms also endows CuPdRM with superior electrocatalytic property for ORR to CuPdS, and other Pd-based electrocatalysts reported recently (SM Table 2). Download: Download high-res image (468KB) Download: ...
The morphological analysis results of chromium in the reaction system at different pH conditions are shown in Fig. 3 and Table 2. Data show chromium mainly exists in Fe–Mn oxide-bound state and organic-bound state on the media surface of hexavalent chromium reduction reaction system. The percen...
reaction time, and cognitive metrics etc., may correlate with the index. This paper only examined five such phenotypes. Follow-up studies expanding the scope of the analysis—both in terms of more diseases and other traits—are already ongoing. For this publication however, we emphasize again th...
