Nitrogen doped tin oxide nanostructured catalysts for selective electrochemical reduction of carbon dioxide to formate

Electrochemical Reduction of Carbon Dioxide on Nitrogen-Doped Carbons: Insights from Isotopic Labeling Studies

Isotopic labeling experiments were performed to better understand the electrochemical reduction of carbon dioxide on nitrogen-doped porous carbon electrodes. By using nonequilibrated solutions of selectively labeled initial carbon sources (i.e., 13CO2 and H13CO3-), bicarbonate anion was identified as the predominant source of the carbon monoxide reduction product.

Metal-free boron-doped graphene for selective electroreduction of carbon dioxide to formic acid/formate.

Herein we report the electrocatalytic activity of boron-doped graphene for the reduction of CO2. Electrolysis takes place at low overpotentials leading exclusively to formate as the product (vis-à-vis benchmark Bi catalyst). Computational studies reveal mechanistic details of CO2 adsorption and subsequent conversion to formic acid/formate.

Highly effective sites and selectivity of nitrogen-doped graphene/CNT catalysts for CO2 electrochemical reduction

Metal-free catalysts, such as graphene/carbon nanostructures, are highly cost-effective to replace expensive noble metals for CO2 reduction if fundamental issues, such as active sites and selectivity, are clearly understood. Using both density functional theory (DFT) and ab initio molecular dynamic calculations, we show that the interplay of N-doping and curvature can effectively tune the activ...

Light Trapping on Plasmonic-Photonic Nanostructured Fluorine- Doped Tin Oxide

Plasmonic Au nanoparticles of ∼50−200 nm in diameter were generated via thermally assisted self-assembly from Au films evaporated on fluorine-doped tin oxide (FTO). A comparative study has been made on the light trapping effects of the plasmonic Au nanoparticles on original FTO and FTO with photonic nanopatterns fabricated using nanoimprint lithography. While strong localized surface plasmon re...
