Abstract

Abstract: Water splitting is considered as a promising technology to solve energy shortage and environmental pollution. Since oxygen evolution reaction (OER) directly affects the efficiency of hydrogen evolution, the preparation of efficient and inexpensive OER catalysts is an urgent problem. "Low‐temperature immersion" (LTI) is expected to be a prospective strategy for electrocatalyst preparation due to its simplicity and energy‐saving advantages. However, there is almost no comprehensive overview on the progress of LTI engineering in the construction of non‐precious metal self‐supported electrocatalysts for OER. Herein, this review firstly introduces the principles and applications of LTI engineering‐assisted preparation of non‐precious metal self‐supported electrocatalysts in terms of etching and deposition. Then the mechanism of OER is analyzed from an amorphous viewpoint, and finally some perspective insights and future challenges of this method are discussed. Abstract : This paper reviews the latest research progress in the preparation of OER catalysts from a new perspective of "low‐temperature immersion" for the first time, which has attracted the attention of researchers for its simplicity and low energy consumption. The review firstly introduces the principles and applications of low‐temperature immersion engineering‐assisted preparation of non‐precious metal self‐supported electrocatalysts in terms of etching and deposition. Then the mechanism of OER is analyzed from an amorphous viewpoint, and finally some perspective insights and future challenges of this method are discussed.
