A hollow porous copper oxide electrode lowers detection potential while improving sensitivity and anti-interference in pesticide sensing.
The Pechini sol-gel route integrates Co3O4, CuO, and MgO phases, controlling crystallinity, 50–70 nm crystallites, and granular morphology.
Engineered CuBr stepped terrace crystal surface accelerates ammonia adsorption kinetics, reducing response time from 75 seconds to 40 seconds.
Adding ferrous ions before reduction controls particle growth, resolving the trade-off between fine particle size and production efficiency.
Cuprous stannate replaces multiple additives to reduce formulation complexity while maintaining polymer strength and suppressing toxic combustion products.
