“…Owing to the results of SEM, the N 2 adsorptiondesorption tests, and the UV-is absorption spectra, we constructed porous CuO-SiO 2 nanocomposites having unique morphologies (e.g., fluffy structures), high surface areas, and narrow optical band gaps. According to the literature (Table S9 †), [66][67][68][69][70] the band gap values of U400/PSSx/Cu 550 °C were close to those of other CuO composite materials. The synthesized CuO-SiO 2 nanocomposites can be used in adsorption-separation applications and as catalysts because of their unique morphologies, high specific surface areas, and narrow band gaps.…”

Carbon monoxide (CO) is well recognized as one of the key intermediates for carbon dioxide (CO2) electrolytic reduction to C2+ products, which has been a hot research field recently. Developing an efficient catalyst that focuses on achieving C-C coupling is highly important for the production of C2+ products. In the present work, we present a feasible approach via the combination of electrostatic assembly and the hydrothermal method of coupling silicon polyanions and copper salts to build an amorphous copper hybrid material wrapped in carbon-silica, denoted as CuO@C-SiO2-X (where X means preparation temperature), as an efficient electrocatalyst for carbon monoxide reduction mainly to liquid C2+ products. The CuO@C-SiO2-X catalyst demonstrated excellent electrocatalytic activity and selectivity, especially to C2+ liquid products with the highest Faradaic efficiency of 81.5%. Additionally, the catalyst showed good stability. The presence of carbon enhanced electronic conductivity, and the silica protected the amorphous CuO from aggregation into crystalline structures. The present work not only provides an efficient catalyst for CO electrocatalytic reduction to liquid C2+ chemicals but also offers a protocol for building Cu-based catalysts with high selectivity to C2+ products in CO reduction.
