Abstract Catalytic conversion of CO 2 to valuable formate provides a pathway carbon neutrality. Indium (In), as promising catalyst, exhibits high selectivity toward due its suitable bonding ability *OCHO intermediates. However, it still suffers from the activation and protonation steps, leading low activity productivity. Here, an oxygen‐pinned stabilization AgIn single‐atom alloy (O p ‐Ag 1 In) is presented for efficiently converting into (≈92.03% Faradaic efficiency) with partial current density 13 mA cm −2 at −0.95 V vs RHE by using standard H‐type reactor. The O In electrocatalyst more effective in because activated sites catalyst regulate step RR formation sufficient amounts *OCHO, which are confirmed situ spectroscopic theoretical calculations. continuous production showcased 70 –2 24 h utilizing flow cell In.

Abstract As a pivotal bio‐based building block, 2,5‐furandicarboxylic acid (FDCA) holds immense and broad application potential in the chemistry industry. Its polymeric derivative, polyethylene furandicarboxylate (PEF), emerges as an appealing alternative to conventional petroleum‐based terephthalate (PET). The electrochemical route for oxidizing 5‐hydroxymethylfurfural (HMF) into FDCA presents significant advantages over thermochemical processes, without requirements of high temperature, pressure, chemical oxidants, precious metal catalysts, featuring higher energy efficiency. Furthermore, electrosynthesis at anode can be synergistically integrated with selective reduction reactions cathode, enabling simultaneous production two desirable value‐added products further enhancing overall utilization This work reviews advancements electrocatalytic HMF (EHTF), encompassing catalyst design, reaction mechanisms, coupling strategies, reactor configurations. It also indicates challenges opportunities EHTF provides insights future development directions.

Superseding the oxygen evolution reaction with thermodynamically favorable and economically attractive organic oxidation is crucial to acquiring eco-friendly hydrogen production via an electrochemical process coupled renewable energy. A bifunctional electrocatalyst, Ru@NixCo1–x(OH)2, featuring a dandelion-liked structure assembled into two-electrode configuration, requires voltage of 1.35 V for cathode H2 anode 2,5-furandicarboxylic acid. The heteronuclear bridging atoms at Ru–Ni sites accelerate water splitting through Volmer–Tafel mechanism enhance *H coverage, as demonstrated by in situ spectroscopy analysis. Simultaneously, Ru–Co serve adsorption 5-hydroxymethylfurfural, achieving 100% Faradic efficiency selectivity. Upon upscaling configuration 2 × cm2 membrane electrode assembly reactor, FDCA rate 243 mg/h was achieved, electricity savings approximately 0.67 kWh/m3 (H2). This work offers promising avenue concurrent biomass upgrading industrial practicability.

Abstract The more sluggish kinetics of hydrogen evolution catalysts in base as compare to that acid some degree restricts production performance hydroxide exchange membrane electrolyzers, especially when using earth‐abundant catalysts. Here a ternary nickel–copper–molybdenum catalyst is reported exhibits ≈5 times higher turnover frequency than without copper doping. X‐ray absorption near‐edge structure and valence band spectrum demonstrate the light doping into nickel–molybdenum alloy modulates electronic downshifts d ‐band center, resulting accelerated desorption, consolidated by H 2 temperature programmed desorption theoretical calculation. An electrolyzer employing this cathode nickel–iron anode, gives current density 1.7 A cm −2 at 2.0 V with pure‐water feed through which outperforms 2025 target proposed United States Department Energy, even operated continuously for over 1000 h decay rate low 0.5 mV −1 . Post‐mortem analysis discloses ionomer migration one key factors affecting long‐term durability. This work demonstrates feasibility low‐cost, water‐fed achieving industrial‐level lifetime.
