Aiming to optimize SnO₂-NiO nanocomposite sensors for detection of hazardous gases, a series of xSnO₂-(1-x) NiO composite nanowebs with different compositions (x = 0.1, 0.3, 0.5, 0.7, and 0.9) were synthesized using an electrospinning process. The formation of long and continuous SnO₂-NiO nanowebs was verified. Depending on the composition, xSnO₂-(1-x) NiO composite nanowebs‎ showed either n-type (SnO₂-rich composition) or p-type (NiO-rich composition) gas-sensing behavior. The best sensing performance was obtained for the nanowebs of 0.5SnO₂-0.5NiO. The presence of plenty of p-n heterojunctions along with the high oxygen adsorption property of NiO were the main reasons for the high response to the NO₂ and C₆H₆ gases at this optimized composition.

为了优化用于检测有害气体的SnO ₂ -NiO纳米复合传感器，使用以下方法合成了一系列具有不同成分（x = 0.1、0.3、0.5、0.7和0.9）的xSnO _2-（1-x）NiO复合纳米网。静电纺丝过程。验证了长而连续的SnO ₂ -NiO纳米纤维网的形成。取决于组成，xSnO _2-（1-x）NiO复合纳米纤维网表现出n型（富SnO _2的组成）或p型（富NiO的组成）气敏行为。对于0.5SnO ₂ -0.5NiO的纳米纤维网，获得了最佳的感测性能。存在大量p - n异质结以及NiO的高氧吸附性能是在这种优化组成下对NO ₂和C ₆ H ₆气体产生高响应的主要原因。
