Pt-based alloys with precisely controllable element distribution are highly sought after in catalysis. This study focuses on optimizing elemental and alloying PtNi alloy nanowires (NWs) through high-temperature heat treatment. The resulting NWs uniform (U-PtNi NWs) demonstrate exceptional stability, attributed to facilitated electron transfer a denser Pt shell, stark contrast untreated that suffer from segregation subsequent performance degradation during electrochemical testing. In methanol oxidation reaction tests, U-PtNi demonstrated mass activity (1562.0 mA mg–1) specific (5.38 cm–2), minimal loss 1000 cycles. work emphasizes the significance of precise component control developing high-performance catalysts presents strategy enhance fuel cell one-dimensional nanocomponent adjustment.

Water electrolyzer is crucial for producing clean hydrogen, but the traditional approach faces challenges owing to oxygen evolution reaction (OER) slow kinetics at anode. Hybrid water splitting replaces OER with oxidation of an organic molecule enhance hydrogen production along value-added products. The scarcity affordable and highly effective catalysts remains a major challenge. MXene, 2D nanomaterial, has gained substantial attention its enviable properties, instance high conductivity, hydrophilicity, surface area. This review discusses experimental methods synthesizing MXene MXene-based nanocomposites. Furthermore, small molecules such as benzyl alcohol, methanol, ethanol, urea, hydrazine, furfural, formic acid alternatives examined. Finally, understanding imminent research development MXene-associated materials in electrocatalytic applications are presented.

In this work, we introduce a unique approach for fabricating three-dimensional (3D) Cu-ZIF-8/MXene, combing the merits of MOFs and MXene to enhance their overall performance. Subsequently, synthesis 3D MXene-based Cu N-doped porous carbon (Cu-NPCM) composites, characterized by high specific surface area, superior conductivity, abundant active sites, was achieved through carbonization acid etching Cu-ZIF-8/MXene. Utilizing resulting Cu-NPCM composites as effective electrocatalyst supports, Ni Pd NPs were uniformly dispersed, preventing aggregation metal NPs. The structure Cu-NPCM, coupled with synergy Pd, facilitates creation interconnected channels rapid reactant product diffusion, along substantial amount OHad, thereby enhancing electrocatalytic efficiency. Remarkably, designed trimetallic Pd/Ni/Cu-NPCM catalyst demonstrates an advanced mass activity 3641.2 mA mgPd–1 in methanol oxidation reaction (MOR), surpassing Pd/Cu-NPCM (2200.5 mgPd–1), Pd/Cu-NPC (1447.1 Pd/C (209.3 mgPd–1) electrocatalysts 1.66, 2.51, 17.4 times, respectively. This research introduces innovative creating support materials electrocatalysts, simultaneously expanding range potential applications direct fuel cells (DMFCs).
