Inorganic nanocatalyst materials created based on elemental integration chemistry

Abstract

Electrochemical hydrogenation using renewable electricity and water as a hydrogen source upgrades wastage chemicals to valuable ones in an environmentally friendly manner. Arrangements and structures of inorganic nanocatalysts dictate their catalytic activities in the electrochemical process. This chapter first summarizes controlling factors of inorganic nanocatalysts in electrochemical CO₂ reduction reactions, which are regarded as a key process for achievement of carbon cycling. Novel electrochemical process promoted on TiO₂-based catalysts are introduced. Electronic power storage via alcohol production from organic acids and ketones, thermoelectric conversion and amino acid synthesis are examples for advanced usage of the electrochemical hydrogenation.
