Solar-driven production of hydrogen and acetaldehyde from ethanol on Ni-Cu bimetallic catalysts with solar-to-fuels conversion efficiency up to 3.8 %

Photo-/thermal synergies in heterogeneous catalysis: Towards low-temperature (solar-driven) processing for sustainable energy and chemicals

“…A similar study of solar-driven ethanol dehydrogenation over Ni-promoted Cu/SiO2 at high activity and selectivity (absence of ethylene, the dehydration product) has just been reported by Luo et al [134] One key difference with the work of Nadeem and Idriss [132] is the significant activity even in the dark state. For example, the dark conversion rate over supported Cu reached ~30 mmol.gcat -1 h -1 and an accurate activation energy determination (Eapp = 92.4 kJ.mol -1 ) was obtained over the range 170-210 °C.…”

Coke and sintering resistant nickel atomically doped with ceria nanosheets for highly efficient solar driven hydrogen production from bioethanol

“…4e). As far as we know, the highest STH efficiency of sunlight driven ethanol dehydrogenation was reported in the study of Ye et al, 20 in which the photothermal ethanol dehydrogenation showed a 3.8% STH efficiency under 6 Suns irradiation. Therefore, the ESR STH efficiency was at least 4 times higher than the previous record.…”

“…Recently, photothermal catalysis has been found to drive ethanol dehydrogenation without fossil energy consumption. 20 However, the ambient solar (3 kW m −2 intensity) irradiated temperature of catalysts was only 130 °C, 20 unable to drive ESR. Therefore, increasing the solar illuminated temperature of catalysts is expected to realize solar driven ESR and solve its fossil energy consumption problem.…”

Coupled Copper–Zinc Catalysts for Electrochemical Reduction of Carbon Dioxide

“…[14][15][16] Owing to its unique feature, Cu is the most studied element and the investigations mainly focus on the effect of the oxidation states of Cu, the influence of the size and shape of the particles, and the development of various Cu-based materials including alloys, composites, complexes, and so on. [13,[17][18][19][20] Particularly, Cu-based bimetallic catalysts attract great interest as their features are highly tunable by changing the type and percentage of the secondary element. Early works showed that alloying Cu with other metals can enhance the selectivity for a specific product and can affect the onset potentials for the formation of some products.…”
