A one-pot synthesis of a monolithic Cu2O/Cu catalyst for efficient ozone decomposition

“…Then, problems such as weak adhesion between the substrate and catalyst powders, sophisticated multi-step or long term integration, and fabrication at high temperatures have been encountered. [23][24][25][26][27] In this study, we successfully propose a one-pot synthesis of the monolithic Cu 2 O nanocatalyst on the surface of a Cu foam by a facile chemical oxidation approach without using additives, which offer superior ozone catalytic performance with high stability and low production cost. This study provides not only a simple synthesis method of the supported catalyst, but also a highly active Cu 2 O/Cu ozone decomposition material.…”

High-performance light-driven heterogeneous CO2 catalysis with near-unity selectivity on metal phosphides

“…Considering only about one tenth of the active Ni 12 P 5 has been utilized in the 10.4 wt% Ni 12 P 5 /SiO 2 sample when compared to pristine Ni 12 P 5 , it is conceivable that the former would be more competitive overall, especially if the system was to be scaled-up. The photothermal effect on 10.4 wt% Ni 12 P 5 /SiO 2 sample was further quantified by using ASPEN Plus software to estimate the local temperature of the catalyst surface based on the experimentally measured CO 2 conversion at reaction equilibrium 4 . Under 2.3 W cm −2 irradiation and using a 5:1 ratio of CO 2 /H 2 , the photocatalytic reaction finally achieved 7.48% CO 2 conversion in the batch reactor after 11.5-h test ( Supplementary Fig.…”

“…n the field of heterogeneous catalysis, gaseous or liquid reactants undergo chemical reactions on the surface of a solid material. These reactions can be enabled thermochemically, electrochemically, biochemically or photochemically [1][2][3][4][5][6][7][8] . The surface reactivity of catalytically active sites is typically discussed in terms of electronic, geometric and support effects [9][10][11][12][13][14][15] .…”

Sub‐3 nm Ultrafine Cu2O for Visible Light Driven Nitrogen Fixation

“…[6] Cuprous oxide (Cu 2 O) is al ow-cost and visible light responsive material, already finding widespread application in photoelectrochemical/photocatalytic conversion processes. [7] Cu 2 Op ossesses appropriate conduction and valence band level for driving N 2 reduction and H 2 Oo xidation, respectively,m aking it an earideal candidate for visible light driven photocatalytic reduction of N 2 to NH 3 in pure water.However,toour knowledge, no prior work examining the photocatalytic performance of Cu 2 Of or N 2 reduction, motivating an exciting attempt and ad etailed investigation. It is worth noting that although the intrinsic properties of Cu 2 Om ake it very suitable as aN RR photocatalyst, the photocatalytic performance of Cu 2 Or emains suboptimal owing to the large size of most Cu 2 O photocatalysts synthesized to date (typically tens to hundreds of nanometers).…”
