  • Spin Manipulation in a Metal-Organic Layer through Mechanical Exfoliation for Highly Selective CO2 Photoreduction

     View Summary

    The manipulation of Fe3+ spin states from high spin (HS; s=5/2) in bulk crystals to mixed spin lattices (with s=5/2 and low spin (LS); s=1/2) is demonstrated in a two-dimensional ultrathin metal-organic layer catalyst by mechanical exfoliation. The resulting catalyst has enhanced activity and selectivity for CO2 photoreduction (CO2RR) over the hydrogen evolution reaction (HER).

  • Amine-Functionalized Diamond Electrode for Boosting CO2 Reduction to CO

    Tatsuhiko Mikami, Takashi Yamamoto, Mai Tomisaki, Yasuaki Einaga

    ACS Sustainable Chemistry & Engineering (American Chemical Society)  10 ( 45 ) 14685 - 14692 2022.11

    Research paper (scientific journal), Joint Work, Corresponding author, Accepted

     View Summary

    Carbon capture, utilization, and storage (CCUS) have been attracting much attention as an initiative to achieve carbon neutrality. In the capture and storage strategy, amines are widely used for highly efficient separation and capturing of CO2 since amines react with CO2 to form carbamates. In the utilization strategy, CO2 electroreduction is a promising method to convert CO2 into value-added compounds because reaction conditions are relatively mild and easily controlled. In this work, toward combining CO2 capture and storage technologies and CO2 electroreduction, we focused on amine modification of the electrode surface, in which boron-doped diamond (BDD) was chosen as a sustainable electrode material. CO2 electroreduction using the amine-modified BDD was performed, and an applied potential dependence of the product selectivity was examined. In situ attenuated total reflectance-infrared measurements showed that the peak intensity of the stretching vibration of the carbonyl group at around 1640 cm-1 decreased as applied potentials became more negative. The effect of amine modification of the BDD surface lies in the formation of a C-N bond during CO2 electroreduction, resulting in the enhancement of the selectivity of CO production up to 8 times compared to the unmodified BDD.

  • Electro-conversion of cumene into acetophenone using boron-doped diamond electrodes

    Beilstein Journal of Organic Chemistry (Beilstein-Institut)  18   1154 - 1158 2022.09

    Research paper (scientific journal), Joint Work, Last author, Corresponding author, Accepted

     View Summary

    A straightforward electro-conversion of cumene into acetophenone has been reported using boron-doped diamond (BDD) electrodes.This particular conversion is driven by the addition reaction of a cathodically generated hydroperoxide anion to an anodically generated cumyl cation, where the BDD’s wide potential window enables the direct anodic oxidation of cumene into the cumyl cation. Since electricity is directly employed as the oxidizing and reducing reagents, the present protocol is easy to use, suitable for scale-up, and inherently safe.

  • Fabrication and electrochemical properties of boron-doped SiC

    Kazuki Uchiyama, Takashi Yamamoto, Yasuaki Einaga

    Carbon (Elsevier BV)  174   240 - 247 2021.04

    Corresponding author, Accepted,  ISSN  0008-6223

     View Summary

    Silicon carbide (SiC) has excellent properties such as chemical and physical stability, biocompatibility, and high thermal conductivity. However, electrical conductivity of SiC is not high enough for electrochemical applications, which has been a major challenge. Here, in order to improve the conductivity, we prepared boron-doped SiC (SiC:B) and evaluated the electrochemical properties. SiC and SiC:B were fabricated by a microwave plasma chemical vapor deposition method. Structural characterization revealed that the main phase of SiC:B is 3C–SiC where the concentration of doped boron could be controlled by tuning the growth conditions. Electrochemical properties were evaluated by cyclic voltammetry measurements, indicating that the reactivity and sensitivity of the SiC:B electrode was comparable of that of the glassy carbon electrode.
