Development of electrochemical reduction process for selective oxidation of hydrocarbons with oxygen

Researcher
Outline

The aim of this study is developing an energy-saving process for the production of value-added chemicals. We focus on an electrochemical method for selective oxidation of hydrocarbons with molecular oxygen, which has been difficult to control until now. Active oxygen species promoting oxygen atom insertion into hydrocarbons would be generated by electrochemical reduction of molecular oxygen. The electron donor should be water rather than hydrogen. This innovative reaction technology will be achieved by a combination of catalytic and electrochemical approaches with chemical engineering approach controlling mass transfer and separation.

Active control of chemical reactions via electric field induced orbital deformation

Researcher
Outline

Applying large external electric field to a molecule will result in the deformation of the molecular orbital. In this research, 1. The reactivity change of molecules through orbital deformation will be investigated, and 2. A method to apply a strong electric field to large number (mole scale) of molecules by utilizing nanogap electrodes will be developed. This will lead to establish a new methodology to actively control a chemical reaction with external electric field.

Control of plasmon-induced chemical reaction by controlling molecular interfaces

Researcher
Outline

Localized surface plasmon (LSP) of metal nanostructures excited with light has been expected as a highly efficient way to convert light energy to chemical energy. This research obtains fundamental knowledge for the design of plasmonic catalysts providing efficient reaction pathways. The reaction pathways and mechanism of plasmon-induced chemical reactions are controlled by controlling the interface between molecules and metals. Furthermore, the control of the plasmon-induced reactions will be achieved on the basis of investigating the elementary process of the reactions at a single-molecule level.

Enhanced Photocatalytic Activity of Hetero-Nanoparticle via Quantum Cutting

Researcher
Outline

Photocatalysis, which converts light energy into chemical energy in fuel, has been attracted much attention, and improvement of their reaction efficiency has been extensively studied. In this research, I will demonstrate the new photocatalytic reaction using quantum cutting process (multiple exciton generation) peculiar to quantum dots. By using photoelectrochemical cell, ultra-high efficiency reaction with external quantum efficiency exceeding 100% at high energy irradiation will be approached. This will be achieved by formation of hetero junction in single semiconductor nanoparticle, which will separate the multiple exciton generated in the photocatalysts via type-II electronic energy structure at the hetero-interface.

I will develop the new catalyst containing hydride material and metal nanoparticles to lower the temperature and pressure of ammonia synthesis process.

Control of Chemical Reaction by Rabi Slitting

Researcher
Outline

How chemical reactions are influenced by molecular vibration is a long-standing question across fundamental physics and chemistry. Coupling of molecular vibration with the optical modes of a microcavity generates new polaritonic states in the infrared region. This phenomenon will be planted into the field of chemical synthesis, resulting in development of a new methodology to manipulate chemical reactions.

Development and Control of Near-IR Light Promoted Reaction Processes

Researcher
Outline

This project focuses on organic reaction processes with near-infrared (near-IR) light. Sunlight is a powerful and sustainable source for organic reaction processes, and visible light promoted organic reactions have been attracted in recent years. An absorption and excitation of a catalyst are required for proceeding the reaction. However, substrates absorbing in the visible light (visible light materials) can not apply to such reactions because both catalyst and substrate absorb the light simultaneously. To overcome this problem, catalysts absorbing near-IR light, which does not interact with visible light materials, are designed by the functionalization of azaporphyrin derivatives. This process may be a novel strategy for late-stage functionalization of visible light materials.
