“…In order to address this problem, other materials are commonly investigated as additives in the NAM. These other materials are conductive ones (such as carbon black and acetylene black), , expanders (such as lignosulfonates), polysaccharide composite, and electric double layer capacitance (EDLC) materials , (like carbons in many forms such as activated carbon, carbon nanotubes, − and graphene − ). However, these materials are not exclusively incorporated into NAM, with other applications also being studied.…”

This work developed a composite of the conducting polymer polyaniline (PAni) with lead that has a high onset potential for hydrogen evolution in a high-concentration acid solution. The aim was to avoid hydrogen evolution from a carbon fiber current collector, considering its application in lead-acid batteries. In a 5 M H 2 SO 4 solution, the onset potential was as high as −0.75 V vs Ag/AgCl. The study revealed that the Pb 2+ ions strongly interact with the nitrogen present in the PAni structure. Xray photoelectron spectroscopy (XPS) and Raman spectroscopy gave an insight into how the interaction between lead ions and the nitrogen takes place, which is described schematically. This composite is stable and keeps the high onset potential, while Pb 2+ is associated with nitrogen, as evaluated in various potentials through chronoamperometry and cyclic voltammetry conditions. The Pb 2+ desorbs for potentials higher than −0.65 V vs Ag/AgCl and degrades the composite onset potential. The desorption was reversible as long as the PbSO 4 particles formed were nanometric and immersed in the PAni. Desorption for long periods forms large PbSO 4 particles; consequently, the reduction of these particles becomes difficult. Without Pb 2+ ions, it is not possible to restore the interaction between Pb 2+ and PAni. Besides XPS and Raman spectroscopy, the material characterization was performed by field emission gun scanning electron microscopy and energy-dispersive X-ray spectroscopy. The electrochemical characterization involved cyclic voltammetry, linear sweep voltammetry, galvanostatic charge−discharge cycles, and chronoamperometry.

Single‐atom catalysts (SACs) have rapidly become a hot topic in photocatalytic research due to their unique physical and chemical properties, high activity, and high selectivity. Among many semiconductor carriers, the special structure of carbon nitride (C3N4) perfectly meets the substrate requirements for stabilizing SACs; they can also compensate for the photocatalytic defects of C3N4 materials by modifying energy bands and electronic structures. Therefore, developing advanced C3N4‐based SACs is of great significance. In this review, we focus on elucidating efficient preparation strategies and the burgeoning photocatalytic applications of C3N4‐based SACs. We also outline prospective strategies for enhancing the performance of SACs and C3N4‐based SACs in the future. A comprehensive array of methodologies is presented for identifying and characterizing C3N4‐based SACs. This includes an exploration of potential atomic catalytic mechanisms through the simulation and regulation of atomic catalytic behaviors and the synergistic effects of single or multiple sites. Subsequently, a forward‐looking perspective is adopted to contemplate the future prospects and challenges associated with C3N4‐based SACs. This encompasses considerations, such as atomic loading, regulatory design, and the integration of machine learning techniques. It is anticipated that this review will stimulate novel insights into the synthesis of high‐load and durable SACs, thereby providing theoretical groundwork for scalable and controllable applications in the field.
