Abstract Biomass is a low-cost, abundant and renewable resource that can be used to manufacture porous carbon-based materials for variety of applications. Different mesoporous carbon supports obtained from the various synthetic approaches are aimed at increasing specific surface area functionalization. Currently, most biomass energy recovery. The circular economy approach could lead development cheap sustainable materials, turning wastes into precious resource. In this review, we provide recent advances in field electrochemistry derived biomass, which offers wider applications proton exchange membrane fuel cells (PEMFCs), anion (AEMFCs) Zn-air batteries (ZABs). focus on understanding required properties role pathways platinum group metal (PGM) free electrocatalysts. promising evaluated towards oxygen reduction reaction (ORR) PEMFC, AEMFC, ZAB. results achieved showed expected performances these conversion devices still lack deployment practice, especially if compared with commercially available PGM-free This review article provides insights how improve actual electrocatalytic activity biomass-derived materials.

Pd-based nanomaterials play a crucial role in fuel cells and electrosynthesis, particularly for electrocatalytic oxidation of small organic molecules. To enhance the catalytic performance catalysts, it is essential to precisely control both surface atomic arrangement electronic structure. In this work, we carried out shape-controlled synthesis nanocrystals alkaline media through an electrochemical square wave potential method. Various shaped with different index facets were prepared including {111}-faceted octahedral Pd (OH NCs), {441}-faceted trisoctahedral (TOH {110}-faceted rhombic dodecahedral (RD PtPd PdPt NCs). The obtained varied structures compositions used as model catalysts study activity ethanol oxidation. result revealed following trend: OH NCs > TOH RD NCs. This provides valuable insights into effects structure alloying on offering strategy design improved catalysts.

Abstract Developing low‐cost and high‐performance nanofiber‐based polyelectrolyte membranes for fuel cell applications is a promising solution to energy depletion. Due the high specific surface area one‐dimensional long‐range continuous structure of nanofiber, ion‐charged groups can be induced form ion transfer channels in nanofiber composite membrane, significantly increasing conductivity membrane. This review stands apart from previous endeavors by offering comprehensive overview strategies employed over past decade utilizing both electrospun natural nanofibers as key components proton exchange anion cells. Electrospun are categorized based on their material properties into two primary groups: (1) ionomer nanofibers, inherently endowed with ability conduct H + (such perfluorosulfonic acid or sulfonated poly(ether ether ketone)) OH − (e.g., FAA‐3), (2) nonionic polymer comprising inert polymers like polyvinylidene difluoride, polytetrafluoroethylene, polyacrylonitrile. Notably, latter often necessitates modifications impart transport channels, given inherent inertness.
