Published: Feb. 7, 2024

Abstract In recent years, single‐atom catalysts (SACs) have become the most active part of catalytic field due to their excellent activity. Among them, Ru SACs exhibit performance in many applications high atomic utilization efficiency, activity and selectivity, relatively low cost. order understand structure–performance relationship potential mechanism SACs, this review summarizes research progress fields electrocatalytic water splitting, fuel cells, nitrogen reduction, nitrate reduction years. The process single atom different synthesis methods modification strategies is summarized. Finally, some opportunities challenges for future development are prospected.

Recently, multifunctional materials have received widespread attention from researchers. Cellulose nanofibers (CNF) is one of biomass with abundant hydroxyl groups, which shows great potential in manufacturing composite material. In this paper, a kind polyaniline@CNF/polyvinyl alcohol-H2SO4 material (PANI@CNF/PVA-H2SO4) was successfully designed by in-situ chemical polymerization conductive polyaniline (PANI) onto CNF aerogel high aspect ratio, and then coated PVA-H2SO4 gel. The has specific capacitance 502.2 F/g at scan rate 5 mV/s as supercapacitor electrode. Furthermore, when the assembled into symmetrical supercapacitor, it can still provide an energy density 11.49 W h/kg power 413.55 W/kg. Besides, as-obtained PANI@CNF/PVA-H2SO4 excellent electromagnetic shielding performance 34.75 dB X-band. addition, due to flexibility PVA, composites be further applied stress sensors detect pressure human motion signals.
