Ce/Gd Co-doping in NiFe LDH Engineered Oxygen Vacancies for Enhanced Oxygen Evolution

Puntos clave

• The research aims to examine how co-doping Ce and Gd in NiFe-LDH enhances oxygen vacancies and improves oxygen evolution performance.
• Co-doping cerium and gadolinium in nickel iron layered double hydroxide (NiFe-LDH)
• Evaluating the distribution of Ce and Gd during the oxygen evolution reaction (OER)
• Assessing the creation of oxygen vacancies
• Ce forms nano-islands of CeO2 while Gd is uniformly dispersed within the structure.
• Increased oxygen vacancies were observed, correlating with enhanced oxygen evolution performance.
