Herein, a water-soluble molecular copper complex was investigated as a catalyst for O reduction in both water and an organic solvent. Although the quasi-stoichiometric oxygen reduction reaction (ORR) for the formation of HO was conducted in an organic solvent and revealed mechanistic insights into the ORR, the electrocatalytic production of HO was achieved in an aqueous medium.

Modulating the oxidation state of copper (Cu) is crucial for enhancing the electrocatalytic CO2 reduction reaction (CO2RR), particularly for facilitating deep reductions to produce methane (CH4) or multi-carbon (C2+) products. However, Cuδ+ sites are thermodynamically unstable, fluctuating their oxidation states under reaction conditions, which complicates their functionality. Incorporating interfacial metal oxides has emerged as an effective strategy for stabilizing these oxidation states.

ConspectusMolecular photoelectrocatalysis, which combines the merits of photocatalysis and organic electrosynthesis, including their green attributes and capacity to offer novel reactivity and selectivity, represents an emerging field in organic chemistry that addresses the growing demands for environmental sustainability and synthetic efficiency. This synergistic approach permits access to a wider range of redox potentials, facilitates redox transformations under gentler electrode potentials, and decreases the use of external harsh redox reagents. Despite these potential advantages, this area did not receive significant attention until 2019, when we and others reported the first examples of modern molecular photoelectrocatalysis.

Bicontinuous metal structures possess unique physical and chemical properties, such as efficient mass transport capability and abundant low-coordinated surface atoms, that make them highly desirable catalysts for various important chemical reactions. Here, we report a one-pot synthesis approach to fabricate bicontinuous Pd nanocubes without a sacrificial template or a dealloying process. The prepared bicontinuous Pd nanocubes have a porous structure consisting of continuous nanosized ligaments, which can enable high atom utilization efficiency and offer abundant low-coordinated surface atoms.

The electrocatalytic conversion of oxygen to hydrogen peroxide offers a promising pathway for sustainable energy production. However, the development of catalysts that are highly active, stable, and cost-effective for hydrogen peroxide synthesis remains a significant challenge. In this study, a novel polyacid-based metal-organic coordination compound (Cu-PW) was synthesized using a hydrothermal approach.

Electrocatalytic oxidation of cyclohexanol/cyclohexanonein water provides a promising strategy for obtaining adipic acid (AA), which is an essential feedstock in the polymer industry. However, this process is impeded by slow kinetics and limited Faradaic efficiency (FE) due to a poor understanding of the reaction mechanism. Herein, NiCo2O4/CeO2 is developed to enable the electrooxidation of cyclohexanol to AA with a 0.
