Electrochemical CO<sub>2</sub> conversion is an important strategy to produce high-value carbon-containing molecules, such as ethylene and ethanol. Despite huge progress in recent years concerning CO<sub>2</sub> reduction catalyst development with increased selectivity, high selectivity for C<sub>2+</sub> products at high current densities is still a challenge. We report the development and optimization of a new surface Al-rich Cu/CuO<sub>x</sub> catalyst with high selectivity for C<sub>2+</sub>-products at high current densities of up to −800 mA cm<sup>−2</sup>.

Biocatalysis, the use of enzymes for synthesis, has emerged as a powerful tool for synthesis of chiral molecules in pharmaceutical and fine chemical industries. Natural enzymes offer inherent stereoselectivity, making them attractive catalysts for this purpose. Peroxidases and cytochrome P450s enzymes utilize an iron-heme cofactor to perform a diverse array of chemical transformations including CH2 hydroxylation, epoxidations, and sulfur-oxidations. Here, we report chiral biocatalytic oxidations in microemulsion media driven by horseradish peroxidase (HRP) coupled with a synthetic Cu2+-polymer

Using CO2 as the primary feedstock offers the potential for high-value utilization of CO2 while forging sustainable pathways for producing valuable products. Electrochemical CO2 reduction, have received extensive attentions for their potential to utilize renewable electricity as energy sources to upgrade CO2 into valuable fuels and chemicals. However, this process is typically limited to producing simple molecules, such as formate, carbon monoxide, ethanol, acetate, and n-propanol. It remains a grand challenge to convert CO2 into more complex molecules at high production rates due to the compl

Achieving efficient CO2 electroreduction for production of valuable chemicals requires affordable, stable, and non-toxic catalysts. One of the most studied and promising products of CO2 reduction is formic acid/formate. The latter species is receiving increased attention as an energy vector [1] or energy storage media (e.g., in CO2 redox flow batteries [2]). At present, the practical application of CO2 reduction to formate still faces challenges due to the lack of electrocatalysts capable of operating at high current densities (> 200 mA cm−2) with low degradation over long-duration operatio

We proposed a concept of an artificial-photosynthetic system to produce pure formic acid using CO2, water, and solar energy, generating no waste, as illustrated in Fig. 1.1 The system consists of an artificial-photosynthetic reaction process and a product isolation process. We proved the concept by small-scale experiments, and constructed a practically large-sized solar-driven CO2 electrolyzer as the first step toward widespread use of artificial photosynthesis.2,3 We adopted a single-compartment configuration of the solar-driven CO2 electrolyzer without ion-exchange membranes and a near-neutr

AbstractThe electrocatalytic conversion of carbon dioxide (CO2) into valuable multicarbon (C2+) compounds offers a promising approach to mitigate CO2 emissions and harness renewable energy. However, achieving precise selectivity for specific C2+ products, such as ethylene and ethanol, remains a formidable challenge. This study shows that incorporating elemental boron (B) into copper (Cu) catalysts provides additional adsorption sites for *CO intermediates, enhancing the selectivity of desirable C2+ products. Additionally, using a nickel single‐atom catalyst (Ni‐SAC) as a *CO source increases l
