A ruthenium-based plasmonic hybrid photocatalyst for aqueous carbon dioxide conversion with a high reaction rate and selectivity

Abstract

A cis-ruthenium complex fixed on a plasmonic Au/TiO2 nanostructure efficiently converts CO2 into formic acid even in low pH water.

Recent Advances of Photocatalytic Hydrogenation of CO2 to Methanol

“…Plasmonic metal nanoparticles with high light absorptivity have been shown to represent a new class of photocatalysts with features that differ dramatically from those of typical semiconductor photocatalysts. Plasmonic nanoparticles have unique optical, electrical, and thermal properties [99][100][101][102][103][104][105][106][107]. In this section, we focused on plasmonic photocatalysts for the photoreduction of CO 2 to methanol.…”

Powering the next industrial revolution: transitioning from nonrenewable energy to solar fuelsviaCO2reduction

“…40,42,44,45,49,[88][89][90] Unlike the water splitting reaction achieved by PEC systems, CO 2 reduction is considerably more complex and presents challenges not otherwise present when H 2 O alone is the substrate of interest. [91][92][93][94][95][96][97][98][99][100][101] First, the generally low solubility and mass transfer of CO 2 in aqueous and organic electrolytes limits the productivity of most PEC cells. Additionally, when performing the reduction in the liquid phase, only C1 products are detected.…”

“…To realise this goal, several attempts have been made to create articial photosynthesis wherein incident light energy facilitates direct photoconversion of CO 2 into viable solar fuels. 63,95,[147][148][149][150][151][152][153][154][155] When considering the general mechanism of chemical reactivity of Cat4 on a quantum level, there are striking similarities to Cat2, especially when comparing to an integrated PEC device. While the following delineation could be qualied as a generality, we will consider such devices which do not require a bias potential or possess a dedicated photoelectrode as Cat4 systems for solar fuel generation.…”

Direct Z-Scheme Tannin–TiO2 Heterostructure for Photocatalytic Gold Ion Recovery from Electronic Waste

“…24 LSPR excitation can generate hot carriers, which can serve as a driving force for chemical reactions and the formation of nanocrystals. 25,26 Our recent work demonstrated that the photochemical activation of TA-coated polymer microspheres can facilitate the adsorption of metal ions. 27 However, the photochemical activity of TA was measured on an inert polymer substrate.…”

“…Moreover, once gold nanoparticles (AuNPs) are formed on the TA surface, localized surface plasmon resonance (LSPR) causes them to extend light absorption from UV light to visible or near-infrared (NIR) light . LSPR excitation can generate hot carriers, which can serve as a driving force for chemical reactions and the formation of nanocrystals. , …”
