Upcycling Spent Cu‐Containing Catalysts to CuO Humidity Sensors for Physiological Detection: Calcination Temperature Optimization

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT To achieve high‐value utilization of spent catalysts, we recovered copper (Cu) from Cu‐bearing spent catalysts via acid‐base leaching to fabricate CuO and systematically studied how calcination temperature affects their microstructure and humidity‐sensing performance. Characterizations show that CuO‐500 (calcined at 500°C) has a large specific
