The rational design and precise fabrication of nanostructured noble metals with sophisticated morphology meliorative electronic structures are the key in development advanced electrode materials for fuel cell technology. Herein, we present a robust controllable stereoassembly method to construction 1D grain boundary-enriched wavy Pd nanowires intertwined 2D ultrathin Ti3C2Tx MXene nanosheets (Pd NWs/MX). By taking series unique architectural merits including interconnected nanowires, rich boundaries, stable 1D/2D heterointerface, direct interaction as well high electrical conductivity, resultant NWs/MX heterojunction expresses excellent electrocatalytic activities, strong antitoxic ability, long lifespan toward both formic acid methanol oxidation reactions, all which significantly superior those widely used particle catalysts supported by conventional carbon matrixes.

Developing efficient bifunctional electrocatalysts is crucial for improving the performance of direct borohydride-hydrogen peroxide fuel cells (DBHPFCs). Here, we present a rational design three-dimensional (3D) hierarchically structured Pd/SnO2/rGO@Ni foam (Pd/SnO2/rGO@NF) self-supporting electrocatalyst. The fabrication process begins with coating two-dimensional rGO nanosheets onto surface nickel (NF) skeleton through simple impregnation method. Subsequently, SnO2 nanorods are vertically grown via hydrothermal method, followed by uniform dispersion Pd nanoparticles using chemical reduction technique, thus forming hierarchical Pd/SnO2/rGO@NF electrocatalyst demonstrates excellent performance, facilitating both hydrogen (H2O2) electroreduction in acidic and basic media sodium borohydride (NaBH4) electrooxidation media. achieves remarkable H2O2 current density 749 mA cm–2 at −1.5 V (408 0.4 media) NaBH4 oxidation 450 0.8 When implemented DBHPFC, shows peak power 116.5 mW cm–2. exceptional electrochemical performances this optimal primarily attributed to its distinct structure application nanocomposites. These results suggest that 3D may serve as potential candidate use
