在不使用催化剂和模板剂的情况下，采用简单的合成方法，成功地制备了一种新型的N，C共掺杂的分级多孔ZnS可见光响应光催化剂。这是在可见光照射下工作的非金属掺杂硫化物半导体光催化剂的第一个实例。通过在开放大气条件下在300、400和500 °C下热分解异硫氰酸锌来形成N，C共掺杂的ZnS催化剂。考察了各种实验条件对催化剂形貌的影响。合成的催化剂的特征在于所需的分析技术。与未掺杂的ZnS相比，N，C共掺杂的催化剂具有结晶良好的纤锌矿结构，并且具有优异的可见光吸收。元素和XPS分析证实了ZnS中同时存在氮元素和碳元素。根据FTIR和XPS结果，讨论了氮和碳的化学性质。可见光在…
A new N, C codoped visible light responsive hierarchical porous ZnS photocatalysts have been successfully synthesized by using a simple procedure in large scale without using catalyst or template. This is a first example of a nonmetal doped sulfide semiconductor photocatalyst working under visible light irradiation. N, C codoped ZnS catalysts were formed by thermal decomposition of zinc isothiocyanate at 300, 400, and 500 °C under open atmospheric conditions. The influences of various experimental conditions on the morphology of the catalysts have been investigated. The synthesized catalysts were characterized by the required analytical techniques. The N, C codoped catalysts possess well-crystallized wurtzite structure and have excellent visible light absorption when compared to undoped ZnS. Elemental and XPS analyses confirmed the presence of both nitrogen and carbon elements in ZnS. The chemical natures of nitrogen and carbon have been discussed on the basis of FTIR and XPS results. The visible light in...
