Abstract:

Herein, we firstly report an ultrafast liquid Joule heating (ULJH) strategy for in situ fabrication and stabilization of NiFe-LDH nanosheets, enhancing the oxygen evolution reaction (OER). ULJH efficiently suppresses agglomeration, yielding ultrathin nanosheets with exposed active edges. At the same time, strong interfacial bonding ensures operational stability. The NiFe-LDH-JH demonstrates exceptional OER performance, achieving a current density of 100 mA cm^-2 at a low overpotential of 262 mV with minimal attenuation after 300 h of operation.

The Joule and Joule–Thomson Experiments

Consider an adiabatic system composed of two chambers, A and B, designed such that no heat flows into or out of the system. Initially, chamber A is filled with a gas at a fixed temperature T1, pressure p1, and volume V1, while chamber B is evacuated. The gas is then gradually forced through a rigid, porous barrier to chamber B, ultimately reaching temperature T2, pressure p2, and volume V2. A piston on the right side maintains a constant pressure (p2), which is lower than p1. The significant...
