Abstract

Amphiphilic SWCNH–In_0.2Cd_0.8S photocatalysts with various contents of amphiphilic SWCNHs have been prepared and characterized. The photocurrent density and H₂ production rate of the 0.38 wt% amphiphilic SWCNH–In_0.2Cd_0.8S photoelectrode (0.38 mA cm⁻² and 3.73 μmol h⁻¹ cm⁻², respectively) were 1.6 and 2.88 times higher, respectively, than those of the bare In_0.2Cd_0.8S photoelectrode. The improved photocatalytic hydrogen evolution efficiency of the 0.38 wt% amphiphilic SWCNH–In_0.2Cd_0.8S photoelectrode is attributed to a synergetic effect of the intrinsic properties of its components, including excellent charge transfer and separation at the interface between the amphiphilic SWCNHs and the In_0.2Cd_0.8S photocatalyst.

增强两亲性单壁纳米碳-In0.2Cd0.8S 复合材料的光催化活性，用于水分离

制备并表征了含有不同含量两亲性 SWCNH 的两亲性 SWCNH-In0.2Cd0.8S 光催化剂。0.38 wt% 两亲性 SWCNH-In0.2Cd0.8S 光电极的光电流密度和氢气产生率（分别为 0.38 mA cm-2 和 3.73 μmol h-1 cm-2）分别是裸 In0.2Cd0.8S 光电极的 1.6 倍和 2.88 倍。0.38 wt% 两亲性 SWCNH-In0.2Cd0.8S 光电极光催化氢进化效率的提高归因于其各组分内在特性的协同效应，包括两亲性 SWCNH 与 In0.2Cd0.8S 光催化剂界面上良好的电荷转移和分离。
