A paired electrocatalysis strategy for intermolecular oxidative cross-dehydrocoupling between styrenes and ethers or -methylphenol derivatives using ketone as a mild oxidant is described. This approach enables the generation of Csp carbon-centered radicals through anodic oxidation, followed by reductive coupling of ketones at the cathode, ultimately yielding valuable oxidative alkylation products.

Nickel electrocatalysis has emerged as a powerful strategy for sustainable C─H activation, offering an environmentally benign alternative to traditional methods based on stoichiometric oxidants. We, herein, report a nickela-electrocatalyzed approach for the expedient synthesis of β-arylated pyrroles via a unique multiple dehydrogenative C─H activation approach. Hence, direct C─C bond formation between pyrroles and arenes was enabled, obviating the need for prefunctionalized substrates.

Furfural (FF) is a biomass-derived platform molecule characterized by an aldehyde group attached to a furan ring. The selective electrochemical hydrogenation (ECH) of the aldehyde group into hydroxymethyl offers a sustainable approach for converting FF into valuable furfuryl alcohol (FA) chemical. Efficient catalyst that balances active hydrogen (H*) generation and FF adsorption is crucial for electrochemical FF-to-FA conversion.

The electrochemical nitrate-to-ammonia conversion (NORR) offers a sustainable route for nitrogen utilization, yet its efficiency is limited by poor nitrate adsorption and sluggish reaction kinetics. Here, a mesoporous FeO electrocatalyst (meso-FeO) with dual geometric and electronic optimization is presented for enhanced NORR performance. Through an in situ electrochemical preactivation strategy (-1.

Regulating the electron-spin state of metal active sites is a rarely cultivated topic for oxygen electrocatalysis. Here, a dual-ligand metal-organic framework (DM) is developed to endow Co sites with crystal symmetry, reconfiguring their orbital degeneracy and electron spin state. The discretized spin-orbital configuration offers the accelerated transformation of the O-related intermediate by accepting electrons via partial d-orbital occupation and mediation of the hydroxyl adsorption strength through electron donation to O p-orbitals.

ConspectusGlobal energy's continuous reliance on fossil fuels has driven unprecedented CO emission growth, intensifying climate volatility through heightened frequency and severity of extreme weather events. These crises underscore the critical need for accelerating innovation in sustainable energy technologies capable of reconciling two urgent imperatives: ensuring reliable energy access while delivering measurable progress toward global decarbonization commitments. Electrocatalytic CO reduction reaction (CORR) technology implementation could not only help to reduce CO concentrations in the atmosphere but also provide new possibilities for renewable energy storage, thus playing a crucial role in driving the energy transition and achieving carbon neutrality.
