Micro-area investigation on electrochemical performance improvement with Co and Mn doping in PbO₂ electrode materials

Abstract

The causes of the increase in electrochemical reactivity are unveiled from a micro perspective through scanning electrochemical microscopy.

PbO2 modified BDD electrode by dicationic ionic liquids assisted electrodeposition for efficient electrocatalytic degradation of pesticide wastewater

“…Figure 1(a) shows that the grain size is about 10 μm and the distribution is dense and uniform (Lv et al 2021). Figure 1(b) shows that the entire crystal plane is distributed in pyramidal clusters, with spherical structure and obvious boundaries, which is consistent with the characteristics of β-PbO 2 description in the literature, indicating that PbO 2 is of good quality (Zhou et al 2021).…”

Electrochemical Properties of Chitosan‐Modified PbO2 as Positive Electrode for Lead–Acid Batteries

“…The probe current in the constant height surface scan can characterize different electrochemical activity distributions, and the probe current is proportional to the electrochemical activity of the substrate. [ 39 ] Figure 8 is the constant height surface scan of the four PbO 2 cathode materials (refer to the scale on the right for the size). The more red the color tends to be, the greater the current, and the more green the color tends to be, the lower the current.…”

Quantitatively differentiating foliar adhesion and absorption of different lead-based particles on Solanum melongena L.

“…S4-S8 †), we infer that the surface of PbX n contains hydroxyl groups (-OH) in addition to its own chemical construction (Pb-S or Pb-O). [32][33][34][35][36][37][38] The more detailed analysis process is provided in Text S11. † Similarly, FT-IR spectra reveal that all PbX n surfaces contained hydroxyl groups (Fig.…”
