Xrd Spectra A And Xps Survey Spectrum B Of Zno Cu Ccg Prepared From The efficiency of co production was only 4%, whereas that of c 2 h 5 oh production was ~10%. c 2 h 5 oh was the product formed at the lowest potential among the co 2 reduction products requiring c. Uniform capping ligands free cu 2 o ncs, including cubic cu 2 o ncs (c cu 2 o) enclosed with {100} crystal planes with different size distributions of 682 ± 92 (denoted as c cu 2 o 682), 109 ±.

The electrochemical co 2 reduction reaction (eco 2 rr) on cu catalysts affords high value added products and is therefore of great practical significance. the outcome and kinetics of eco 2 rr remain insufficient, requiring essentially the optimized structure design for the employed cu catalyst, and also the fine synthesis controls. The reduction of mb, cr, and mo by the different catalysts corresponds to a pseudo first order kinetic model. zno cu ccg exhibits the highest k at 80 sec for the catalytic degradation of the three dyes. in addition, zno cu ccg, cu ccg, and zno ccg also exhibit higher k values than the pure zno cu, cu, and zno nps at all reaction times.

The cu 0 cu interface is further constructed by using the cu 2 o (111) and cu (111) surfaces to simulate the elementary steps of co 2 reduction to different c 2 products because it is found that the (111) surface of the cu 0 cu interface is the most stable one (table s6). the cu 2 o (111) and cu (111. This suggests that cu single atoms could stabilize the adsorption of co and facilitate its subsequent pcet process to generate hydrocarbons. for 1.4 cu 1 w 18 o 49 sample, apart from co production, it exhibited ch 4 and c 2 h 4 production rates of 5.7 and 0.33 µmol g −1 h −1, respectively, with a low selectivity of 6.7% for c 2 h 4 product.
