Nano-Micro Letters, Journal Year: 2025, Volume and Issue: 17(1)

Published: March 28, 2025

Abstract Harnessing solar energy to enhance the rechargeable zinc–air batteries (RZABs) performance is a promising avenue toward sustainable storage and conversion. Simultaneously enhancing light-absorption capacity carrier separation efficiency in nanomaterials, as well improving electrical conductivity configuration for electrocatalysis, presents formidable challenge due inherent trade-offs interdependencies. Here, we have developed Janus dual-atom catalyst (JDAC) with bifunctional centers efficient charge electrocatalytic through bipolar doping strategy. The situ X-ray absorption near-edge structure Raman spectroscopy analyses demonstrated that Ni Fe JDAC not only function effective sites oxygen evolution reaction reduction reaction, respectively, but also serve hole electron enrichment sites, effectively suppressing photoelectron recombination while photocurrent generation. As result, assembled JDAC-based light-assisted RZABs exhibited extraordinary stability at large current densities. This work delivers pivotal insight design catalysts efficiently convert into electric chemical energy.

Constructing Built‐in Electric Field in Heterogeneous Flower‐Like SnS₂@Few‐Layer Ti₃C₂ for Enhanced Charge Transfer Kinetics in Lithium‐ion Capacitors

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 7, 2025

Abstract Lithium‐ion capacitors (LICs) are considered promising advanced energy storage devices due to their combination of high and power density. However, the inherent mismatch in charge rate between anode cathode has forced search for materials with accelerated reaction kinetics. Herein, heterogeneous flower‐like SnS 2 @few‐layer Ti 3 C (SnS @f‐Ti ) composites asymmetric distribution through Sn─O─Ti bonded prepared, which can regulate electronic structure active sites. Moreover, presence f‐Ti substrate suppresses volume expansion , while alleviates interlayer stacking increases sites during charging/discharging processes. Consequently, LICs consisting activated carbon (AC) display density (6.67 kW kg −1 ), (126.26 Wh superior stability. Furthermore, functional theory (DFT) calculations experimental characterizations reveal that built‐in electric field, induced by modulating work function MXene, enables directional electron transfer interfaces, thereby lowering diffusion barrier Li ions boosting electrochemical kinetics composites. This provides guidance designing unique surface‐interface structures carrier transport heterojunctions.
