Magnetic-Field-Regulated TiO2 {100} Facets: A Strategy for C-C Coupling in CO2 Photocatalytic Conversion

Abstract: Solar-driven CO 2 conversion is an attractive option for producing usable fuels and chemicals. However, traditionally synthesized TiO 2 materials suffer from the low activity of CO 2 conversion into multi-carbon products. Here, for the first time, strong magnetic fields were introduced into TiO 2 synthesis, and new TiO 2 {100} facets containing more active low-coordinate Ti atoms were developed. This is beneficial to the coupling of adsorbed CO*, which enables highly efficient CO 2 conversion into C 2 H 5 OH w… Show more

“…The absorption bands at 1467, 1435, and 1358 cm –1 could be assigned to the carbonates. [ 21 ] Moreover, the weaker peak at 2087 cm –1 corresponds to the *CO, [ 20c,22 ] which is a critical intermediate of final product CO. This result is consistent with the previous reports, [ 23 ] confirming that the reaction pathway of CO 2 RR involved the *COOH and *CO intermediates.…”

“…[7][8][9][10][11][12] Controlling the exposed facets in these nanocrystal-based materials could change the distance, the arrangement, and the density of the atoms on the surface, further optimizing the adsorption energy of the intermedia during the reaction. [13][14][15][16][17][18][19][20][21] Thus, many studies have shown that controlling surface structures of crystalline catalysts is important, and have reported that the exposed facet in nanocatalysts affected both reactivity and selectivity. [22][23][24][25][26] Porous crystalline materials have gained attentions due to their high surface areas, large pore volumes, tunable channel connectivities, and modifiable surfaces.…”

“…Jiang et al. [ 21 ] reported that the C2 product of a {100} crystal plane TiO 2 under an external magnetic field is 22 times that of the original TiO 2 , but the simultaneous production of various C1 products results in the imperfect selectivity of CC coupling, less than 90%. Therefore, the selectivity of CO 2 PR still has a lot of meaningful research space.…”

“…Li et al [20] built a three-phase interface to make Pt at a suitable gas-liquid interface, and achieved a yield rate of 136 µmol g −1 h −1 and a selectivity of 65.5% of CH 4 , by adding Na 2 S and Na 2 SO 3 as a sacrificial agent.
