(471f) Heterostructured Nanocatalysts for Electrochemical Energy Conversion Reactions

Developing a clean and sustainable energy system is essential for the earth's sustainability. The hydrogen/water energy cycle, a clean and sustainable system, receives of great interest recently. Water splitting and formation are the key reactions in the hydrogen/water energy cycle. Developing active and cost effective nanocatalysts for water splitting and formation is important to water splitting for the production of clean H₂ energy sources and for the production of electricity efficiently. This work will present various nanocatalysts for electric driven water splitting and formation reactions, especially for hydrogen evolution reaction (HER), oxygen evolution reaction (OER), and oxygen reduction reaction (ORR). The M/LDHs, MO/LDHs, and MO/M heterostructured electrocatalysts were prepared by various interfacial engineering techniques. Combining advanced characterization and DFT computational techniques is capable of providing the insight of the heterostructured nanocatalysts for HER, OER and ORR. It was found that the heterostructured interface plays a vital role and provides a highly active catalyst for water splitting and formation. The design strategy for the HER or OER or ORR catalysts can be developed via the understanding of the interfacial properties and reactions.
