Self-doped TiO2 nanotubes with surface modification by ionic liquids for enhanced photoreduction of CO2 to acetic acid

Synergy of Photo- and Photothermal-catalytic Synthesis of Methyl Propionate from Ethylene and Carbon Dioxide over B–TiO2/Ru

“…17 However, these reactions only convert CO 2 to C1 compounds, and few of them realized the growth of the carbon skeleton by photocatalysis of CO 2 . 18,19 Methyl propionate (MP), as an important chemical raw material, has wide applications in the fields of spices, drugs, and materials. 20,21 In recent years, the preparation of MP via methoxycarbonylation of ethylene (EMC) is an ideal and atomic-economic route.…”

“…At present, there are many reports of photocatalytic reduction of CO 2 to CO, CH 4 , HCOOH, or CH 3 OH . However, these reactions only convert CO 2 to C1 compounds, and few of them realized the growth of the carbon skeleton by photocatalysis of CO 2 . , …”

Exploring the effect of the reaction conditions on the mechanism of the photocatalytic reduction of CO2 in the vapor phase over Pt/TiO2: an operando FTIR study

“…2 Moreover, recent studies have also evidenced the formation of C2 products through C-C coupling mechanisms, such as ethane (C 2 H 6 ), ethanol (C 2 H 5 OH), ethylene (C 2 H 4 ) and acetic acid (CH 3 COOH). [3][4][5] Among the various semiconductors utilized as photocatalysts, titania (TiO 2 ) is widely employed due to its numerous advantages, including its low cost, low toxicity, and robust catalytic activity in the UV range. 6 However, limited photoresponse in the visible range (light-absorption onset of bulk titania typically occurs around 380-400 nm), fast charge recombination, and catalytic deactivation are significant factors that contribute to its insufficient photocatalytic performance.…”
