Bismuth-Nanoparticles-Embedded Porous Carbon Derived from Seed Husks as High-Performance for Anode Energy Electrode

Abstract

In energy application technology, the anode part of the electrode is typically composed of carbon-coated materials that exhibit excellent electrochemical performance. The carbon-coated electrodes facilitate electrochemical reactions involving the fuel and the oxidant. Energy electrodes are used in stationary power plants to generate electricity for the grid. These large-scale installations are known as distributed generation systems and contribute to grid stability and reliability. Understanding the practical applications of energy materials remains a significant hurdle in the way of commercialization. An anode electrode has one key limitation, specifically with alloy-type candidates, as they tend to exhibit rapid capacity degradation during cycling due to volume expansion. Herein, biomass-derived carbon from sunflowers (seeds husks) via pyrolysis and then bismuth nanoparticles are treated with carbon via a simple wet-chemical method. The electrode Bi@C offers several structural advantages, such as high capacity, good cycling stability, and exceptional capability at the current rate of 500 mA g−1, delivering a capacity of 731.8 mAh g−1 for 200 cycles. The biomass-derived carbon coating protects the bismuth nanoparticles and contributes to enhanced electronic conductivity. Additionally, we anticipate the use of low-cost biomass with hybrid composition has the potential to foster environment-friendly practices in the development of next-generation advanced fuel cell technology.

“…Therefore, the bare surface of each BiNP is stabilized via the ligation of phenolic OH and COO − groups of the TA, gluconic acid, and gallic acid moieties. 45 A stable and strong ligation was observed at 80 °C via interactions of active functional groups in TA and gallic acid that produced a chemically cross-linked organic network structure with a highly porous Bi/TANP surface.…”

“…In addition, lighter elements such as C, O, and H present in the TA layer cannot scatter the high-energy electron beams and thus mostly passed through these elemental layers and the coating of TA could be transparent.
