This work demonstrates the formation of self‐ordered double‐walled ZrO 2 nanotube array via electrochemical anodization in glycerol‐based electrolyte. Compared with its counterpart of single‐walled ZrO 2 nanotube array, the tube wall of double‐walled ZrO 2 nanotube split into outer and inner layers for the decomposition of glycerol during anodization process. Moreover, the double‐walled structure showed its advantage of achieving improved utilization of light and higher specific surface area of nanotube array. Due to the unique double‐walled structure, the double‐walled ZrO 2 nanotube array exhibited better photocatalytic activity than the single‐walled ZrO 2 nanotube array.
