　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

　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

　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

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.
