Comments on “Interlayer Atomic Voids by Partial Cesium Defect in Layered Titanate Activate Photo(electro)catalytic H 2 and O 2 Generation”

Key Points

• The aim is to propose an alternative explanation for the formation of interlayer cesium voids in layered titanate materials.
• Analyzing the treatment process involving aqueous solution of cetyltrimethylammonium bromide and heat treatment at 700 °C.
• Investigating unintended proton exchange in the medium.
• Discussing thermal dehydration and dehydroxylation processes leading to anatase formation.
• The proposed explanation aligns with classical chemistry principles of layered materials.
• Unintended proton exchange may play a significant role in void formation.
• Thermal processes contribute to the transformation of titanates into defective structures.
