The optimized cupric oxide nanoparticles on gas diffusion electrodes exhibited ultra-high-rate CO₂ reduction reactions to multicarbon products with a current density of 1.7 A cm⁻² in neutral electrolytes.

CO₂ reduction in gas diffusion electrodes is modeled using direct numerical simulation, with species transport resolved in 2D throughout the catalyst layer, including steric effects. Modeling yields numerous ways to optimize GDE performance.

With electron-rich pyrimidine rings introduced, the obtained crystalline PCN is favored with rationally modulated band and electronic structures, resulting in efficient photocatalytic hydrogen evolution and benzyl alcohol selective oxidation.

Single-atomic Re on 1T-2H MoS₂ heterostructure demonstrates HER performance on par with Pt/C electrocatalyst. This good performance is attributed to the introduction of Re single atoms that promote phase transition and serve as active sites for water dissociation.

In a Rh/CrO_x core–shell cocatalyst for water-splitting photocatalysts, CrO_x serves as an electron pathway, transfers the photoexcited electrons from photocatalysts to Rh (reduction site), and improves the H₂ evolution activity.

Phase shuttling of Pb₃O₄ leads to the reconstructed β-PbO₂ phase and significantly enhances the electrochemical ozone production (EOP) through water oxidation.

The production of acetic acid from CO₂ is tuned by the atomic ordering and optimized chemical bonding in ternary chalcogenides.

Cr₁–O₄ as an active site in the Cr₁/ZSM-5 SAC can catalyze the DOM to form value-added C1 oxygenated products with a productivity of 21 100 μmol g_cat⁻¹ h⁻¹ and a selectivity of 99.8% at 50 °C within 30 min, which outperforms most state-of-the-art catalysts.

The defect-copper chalcopyrite CuGa₃Se₅ is a promising photocathode material for solar hydrogen generation. Here we assess its performance with photoelectrochemical measurements and vibrating Kelvin probe surface photovoltage spectroscopy.

Detailed investigation of photocatalysts, cocatalysts and redox mediators provides a Z-scheme overall water splitting system operating under long-wavelength visible light.
