Abstract Electrocatalytic 5-hydroxymethylfurfural oxidation reaction (HMFOR) provides a promising strategy to convert biomass derivative high-value-added chemicals. Herein, cascade is proposed construct Pd–NiCo 2 O 4 electrocatalyst by Pd loading on Ni-doped Co 3 and for highly active stable synergistic HMF oxidation. An elevated current density of 800 mA cm –2 can be achieved at 1.5 V, both Faradaic efficiency yield 2,5-furandicarboxylic acid remained close 100% over 10 consecutive electrolysis. Experimental theoretical results unveil that the introduction atoms modulate local electronic structure Ni/Co, which not only balances competitive adsorption OH – species, but also promote Ni 3+ species formation, inducing high indirect activity. We have discovered incorporation facilitates 2+ pre-oxidation electrophilic OH* generation contribute direct process. This work new approach design advanced upgrading.

The general understanding on the reaction path is that electrocatalytic N2 reduction follows either individual associative alternating or distal pathways, where efficient activation and selective NH3 production are very challenging. Herein, an unconventional "alternating-distal" pathway was achieved by shifting "*NHNH2→*NH2NH2" to "*NHNH2→*NH + NH3" step boost synthesis with amorphous CeMnOx electrocatalyst. In this process, realized through π back donation Mn site, while Mn/Ce dual active sites could regulate intermediate configurations avoid nitrogen-containing by-product formation. Such affirmed in situ spectroscopic analyses theoretical calculations. a neutral media, average ammonia rate of 82.8 µg h-1 mg-1 outstanding Faradaic efficiency 37.3% were attained. This work validated mechanism synthesis, which might be extended other catalytic process multiple possible paths.

The past decade has seen significant progress in proton exchange membrane water electrolyzers (PEMWE), but the growing demand for cost-effective electrolytic hydrogen pushes higher efficiency at lower costs. As a complex system, performance of PEMWE is governed by combination multiscale factors. This review summarizes latest from quantum to macroscopic scales. At level, electron spin configurations can be optimized enhance catalytic activity. nano and meso scales, advancements atomic structure optimization, crystal phase engineering, heterostructure design improve mass transport. macro scale, innovative techniques gas bubble management internal resistance reduction drive further gains under ampere-level operating conditions. These modifications level cascade through meso- macro-scales, affecting charge transfer, reaction kinetics, evolution management. Unlike conventional approaches that focus solely on one scale-either catalyst (e.g., atomic, or modifications) device porous transport layers design)-combining optimizations unlocks greater improvements. Finally, perspective future opportunities engineering anode toward commercial viability offered.
