Innovative Optimized Design of CeO₂/SnO₂ Composites for Power Equipment Oil Achieving Breakthrough in High-Performance H₂ Gas Sensing.

ABSTRACT: Monitoring changes in the dissolved gas compositional within transformer oil, particularly hydrogen (H₂), is vital for early fault diagnosis. Among various sensing materials, SnO₂ shows promise for H₂ gas detection but faces challenges, such as high operating temperatures, poor selectivity, and slow response/recovery kinetics. This study successfully synthesizes a series of CeO₂/SnO₂ composite materials with varying Ce/Sn molar ratios using a hydrothermal method, followed by calcination. The impact of the composite ratio on its microstructure, surface chemistry, and H₂ gas-sensing performance has been systematically explored. The strategic incorporation of CeO₂ significantly boosts the surface oxygen vacancy conce
