Advanced Functional Materials, Volume 34, Issue 50, December 9, 2024.Wide‐bandgap and air‐stable perovskite‐inspired materials (PIMs) are low‐toxicity alternatives to lead‐halide perovskites (LHPs). However, the optoelectronic performance of PIMs is far inferior to that of the LHPs, particularly due to a high defect density.

ChemistrySelect, Volume 9, Issue 14, April 12, 2024.Zn/Al and Zn/Al−Co(0.3) hydrotalcites were synthesized via the co‐precipitation method. After the calcination process, both materials exhibited photocatalytic activity in phenol degradation. However, the incorporation of cobalt promotes the formation of surface defects such as oxygen vacancies, favoring the adsorption of oxygen species and enhancing ...
