Light-driven carbon dioxide reduction over the Ag-decorated modified TS-1 zeolite

Abstract

Light-driven reduction of CO2 to high value-added fuel has shown great potential in reducing CO2 emissions and solving energy crisis. Herein, Cu ions-exchanged mesoporous zeolite TS-1 (Cu-TS-1) with rich Ti3+-VO...

“…[160] Additionally, as DFT calculations support the elucidation of the reaction mechanism, in situ and operando characterization methods certainly help investigate the CO 2 reduction mechanism as ex situ analysis is inadequate to demonstrate what intermediates generate during reaction on the surface due to possible contamination of the surface and unintended transformation of materials. In some works covered in this review, what kinds of bonds were present in the intermediates was revealed by in situ infrared spectroscopy (FT-IR, ATR-IR, DRIFTS) and in situ Raman spectroscopy, [83,84,87,[106][107][108]110,112,124,129] and a chemical state of catalyst was monitored with in situ and operando XAS and operando APXPS. [102,108,125] Based on the results from these characterizations, more reliable reaction mechanisms were proposed.…”

“…Inspired by the zeolite properties of high surface area, ion exchange ability, and increasing stability of metal oxides originating from the micro-mesoporous structure and LSPR effect of plasmon particles of visible-light absorption, Li et al synthesized a TS-1 zeolite modified with Cu ions and Ag cocatalyst. [129] This Cu-modified TS-1 zeolite (Cu-TS-1) had a mesoporous structure with rich oxygen vacancies, and Cu existed mainly as Cu 2 O and CuO. Owing to the characteristic structure of zeolite, Cu species could be well dispersed and stabilized, and the concentration of CO 2 at the surface could increase under the reaction conditions.…”
