Remarkable enhancement in the electrochemical activity of

2019/5/1The electrochemical reversibility of maricite NaFePO 4 is highly dependent on the rational design of the nanostructure. We propose, for the first time, an effective strategy of applying an acid-etched carbon cloth (eCC) as the substrate to be loaded with NaFePO 4 C and significantly enhance the electrochemical activity of the maricite.

We show through combined cyclic voltametry and Raman spectroscopy measurements that the enhanced electrochemical activity lies in the films textural evolution. By purposely acting on the LiFePO4 film texturation we succeeded for the first time in preparing, through chemical oxidation, fully delithiated heterosite-type FePO4 thin films.

This paper aimed to improve the electrochemical activity of a pitch-derived open-pore graphite foam (GF) by an electrochemical coating of reduced graphene oxide (RGO) and platinum particles without significantly affecting its 3D-structure. RGO was synthesized using cyclic voltammetry (CV) from a 3 g Lminus;1 GO and 0.1 M LiClO4 solution. For the electrodeposition of Pt particles, an

Electrochemical biosensors: perspective on functional

2020/2/4Employing functional nanomaterials used as a supporting matrix for signal enhancement has gained attention for high-performance electrochemical analysis []. Nanomaterials endow the large surface area, enabling support increased loading capacity and the mass transport of reactants, which results in a synergic influence for signal amplification [ 8 ].

Understanding the electric and nonelectric field

Electrolyte cations affect the activity of surface-mediated electrocatalytic reactions; however, understanding the modes of interaction between cations and reaction intermediates remains lacking. We show that larger alkali metal cations (excluding the thickness of the hydration shell) promote the electrochemical CO reduction reaction on polycrystalline Cu surfaces in alkaline electrolytes

Electrochemical work was applied to investigate the electrochemical properties of CSAC and HCSAC. The results obtained showed that plasma modification improved the specific capacitance of CSAC by 64.8% (current density, 1 A g −1 ; electrolyte, 6 M KOH solution) within 100 s.

Role of AuxPt1–x Clusters in the Enhancement of the

This study quantitatively elucidates the role of metal clusters in the electrochemical activation of metal-oxide nanostructured electrodes. Through the deposition of nearly monodisperse Au x Pt 1–x (x = 0, 0.5, 1) clusters, smaller than 3 nm, on the ZnO nanorod (NR) electrode surface, a controlled enhancement of charge transfer and activation of electrocatalytic processes was achieved.

Locally enhanced electric fields produced by high-curvature structures have been reported to boost the charge transport process and improve the relevant catalytic activity. However, no visual evidence has been achieved to support this new electrochemical mechanism. Here, accelerated electrochemiluminescence (ECL) reactions emitting light are visualized for the first time at the
