In situ preparation of polymeric cobalt phthalocyanine–decorated TiO2 nanorods for efficient photocatalytic CO2 reduction

Monolayer Molecular Functionalization Enabled by Acid–Base Interaction for High-Performance Photochemical CO2 Reduction

“…Its catalytic performance can be enhanced by both hybridization with carbon nanotubes and tuning of the electronic properties of the Pc ligand to enable more efficient production of CO or generation of liquid products such as methanol. − However, there has been only a limited number of studies exploring CoPc as a catalyst for photochemical CO 2 reduction. Additionally, previous studies commonly use CoPc as a light absorber but not a cocatalyst. − Recently, Ouyang et al constructed a molecular assembly of a CoPc cocatalyst and a pyridine-appended iridium photosensitizer, which gave quantum yields of up to 27.9% for CO 2 reduction to CO but relies on noble metal materials . Similar molecular structures, such as Co quaterpyridine complexes and polymeric CoPc, have been loaded onto CN x to generate systems for CO 2 photoreduction. ,, Nevertheless, the reaction rate or turnover frequency (TOF) remains relatively low.…”

Progress and perspectives on 1D nanostructured catalysts applied in photo(electro)catalytic reduction of CO2

“…For example, the light-absorbing ability of the catalyst could be significantly improved by loading the polymeric cobalt phthalocyanines (CoPPcs) on TiO 2 NRs as a photosensitizer. 183 In addition, the heterojunction formed by p-type TiO 2 and n-type CoPPcs could promote the separation of carriers. Similarly, Yang et al anchored Cu 2 O NPs on TiO 2 NRs.…”

On the one hand, the working range of photocatalysts can be extended to visible light and even nearinfrared light.…”

A critical review on emerging photocatalysts for syngas generation via CO2 reduction under aqueous media: a sustainable paradigm

“…126 There are several excellent research/review articles on TiO 2 -based photocatalysts for CO 2 reduction with H 2 O into various upgraded products including CO, CH 4 , HCOOH, HCOH, and CH 3 OH. 26,127–129 However, in the following section, we have deliberately placed an emphasis on TiO 2 -based photocatalysts for CO 2 reduction with H 2 O for the production of syngas (CO + H 2 ) only.…”
