This review presents the synthesis, evaluation, and characterization of non-TiO₂-based photoanodes for photoelectrocatalytic (PEC) wastewater treatment, revealing the synthesis–structure–mechanism–activity relationship.

A review highlighting the current progress, challenges, and opportunities in integrated electrochemical CO₂ capture and conversion for the direct reduction of the captured CO₂-adduct.

Introducing a built-in electric field/external stimuli is an efficient strategy to promote the nitrate reduction reaction for ammonia production.

A self-renewal Fe–N–C catalyst with fourfold higher Fe loading and strong FePPc–CNT interactions, showing high ORR activity and stability in acid. A unique self-renewal mechanism sustains activity by exposing fresh Fe–N₄ sites over time.

In situ spectroscopies reveal the increase of Fe and Ni valence states during oxygen evolution in anion-exchange-membrane water electrolyzers (AEMWE) for hydrogen production.

A single-atom zinc catalyst prepared by loading zinc phthalocyanine on carbon nanotubes enables highly efficient transformation of biomass-derived furfural to hydrofuroin, a sustainable aviation fuel precursor, with near-unity efficiency.

Mo–Ni single atom pairs supported on N-doped carbon efficiently and selectively produce urea (yield of 11.3 mmol g⁻¹ h⁻¹ and 31.8%) from nitrates and CO₂ upon optimized pulsed electrochemical reduction conditions (−0.5/−0.7 V vs. RHE).

Simultaneous elevation of temperature and CO₂ pressure enables industrially relevant CO selectivity and current density in MEA electrolyzers, overcoming mass transport limitations of dilute CO₂ feedstocks.

Benzodithiophene-incorporated polymers, synthesized via a two-step polymerization process, enhance photocatalytic efficiency by optimizing donor–acceptor interactions within the polymer matrix and facilitating efficient charge separation.

Ir/terpyridine-based solid molecular catalysts facilitate efficient base-free formic acid dehydrogenation both in batch and continuous operation. A kinetic isotope effect study highlights β-hydride elimination as a rate-determining step.

The Lewis acidity of Ni²⁺ and Fe³⁺ ions in a layered double hydroxide (LDH) was enhanced by incorporating the lanthanide dopant Ce, tuning the surface electronic configurations to prefer OH* adsorption over Cl* adsorption.

During HIROF growth on metallic Ir, an anhydrous IrO₂ layer forms on all nanoparticles. As smaller nanoparticles are more oxophilic due to the Gibbs–Thomson effect, IrO₂ is more difficult to reduce. This impedes further oxidation and HIROF formation.

Engineering copper nanoparticles to achieve high dispersion and thermal stability with stable catalytic activity is crucial and challenging for the direct hydrogenation of CO₂ to oxygenates via tandem catalysis over hybridized catalysts.
