We report the first use of polymeric carbon nitride (CN) for the catalytic selective oxidation of H₂S. The as-prepared CN with unique ultrathin “nanomeshes” structure exhibits excellent H₂S conversion and high S selectivity. In particular, the CN nanomesh also displays better durability in the desulfurization reaction than traditional catalysts, such as carbon- and iron-based materials.

聚合氮化碳纳米网作为一种高效，耐用的无金属催化剂，用于氧化脱硫

我们报道了聚合氮化碳（CN）首次用于H ₂ S的催化选择性氧化。制备的具有独特的超薄“纳米颗粒”结构的CN表现出出色的H ₂ S转化率和高S选择性。尤其是，CN纳米筛网在脱硫反应中也显示出比传统催化剂（例如碳基和铁基材料）更好的耐久性。
