Development of inorganic nanocatalyst materials based on elemental integration chemistry

Abstract

This chapter discusses compositions, arrangements, and structures of inorganic nanocatalysts that electrochemically promotes material conversion using water as a hydrogen source and introduces the functions of the nanocatalysts. First, the author summarizes the controlling factors of inorganic nanocatalysts applicable to CO₂ reduction reactions, which are regarded as a critical technology for achieving carbon cycling. TiO₂-based catalysts electrochemically produce alcoholic compounds from organic acids and ketones, a new method for highly efficient power storage. Furthermore, thermoelectric conversion and amino acid synthesis on the TiO₂ electrocatalyst are introduced as an advanced application of electrochemical reduction of organic acids and ketones.
