研究人员通过水热法合成钨掺杂镍钛酸镍(WNiTiO3)纳米颗粒，系统研究了W掺杂浓度对NiTiO3物理化学及电学特性的影响。结果表明，W掺杂导致晶粒尺寸减小、带隙窄化(2.90→2.78 eV)，并显著提升H2S气敏性能，10 mM掺杂样品在250°C下对100 ppm H2S响应值达88.66，响应/恢复 ...

Hydrogen sulfide (H 2 S) poses an exceptionally high risk for industrial workers, especially those in the oil and natural gas industry. Oil fields rich in sulfur and H 2 S can lead to contamination of ...
