초록

$Cd_{0.5}Zn_{0.5}S/ZnO$ 형태의 복합체 광촉매를 침전법으로 제조하였고, 이들 화합물의 특성을 XRD, UV-vis DRS, PL 및 FE-SEM 등을 이용하여 조사하였다. 그리고 가시광선 조사 하에서의 로다민 B 분해반응에 대한 광촉매로서의 활성을 조사하였다. ZnO와는 달리 $Cd_{0.5}Zn_{0.5}S/ZnO$는 자외선 뿐만 아니라 가시광선 영역의 빛도 효율적으로 흡수하며 특히 $Cd_{0.5}Zn_{0.5}S$의 함량 증가에 따라 가시광선 영역의 빛에 대한 흡광도도 증가하였다. 또한 $Cd_{0.5}Zn_{0.5}S/ZnO$에 있어서 $Cd_{0.5}Zn_{0.5}S$의 함량이 증가할수록 최종 입자들의 크기가 작아지고 그 결과 비 표면적이 증가하였다. 로다민 B의 광분해 반응에 있어서는 $Cd_{0.5}Zn_{0.5}S$ 함량이 높은 $Cd_{0.5}Zn_{0.5}S/ZnO$ 촉매일수록 상대적으로 높은 광촉매 활성을 보여주었다. 그러므로 $Cd_{0.5}Zn_{0.5}S/ZnO$ 광촉매의 활성에 있어서는 촉매의 흡착능력 뿐만 아니라 $Cd_{0.5}Zn_{0.5}S$와 ZnO 사이의 heterojunction 효과도 중요하게 작용하는 것으로 보인다.

$Cd_{0.5}Zn_{0.5}S/ZnO$ composite photocatalysts were synthesized using the precipitation method and characterized by XRD, UV-vis DRS, PL and FE-SEM. Photocatalytic activities of the materials were evaluated by measuring the degradation of rhodamine B under visible light irradiation. Contrary to ZnO, $Cd_{0.5}Zn_{0.5}S/ZnO$ materials absorb visible light as well as UV and their absorption intensities in visible region increased with increasing the $Cd_{0.5}Zn_{0.5}S$ amount. The increment in the $Cd_{0.5}Zn_{0.5}S$ content in $Cd_{0.5}Zn_{0.5}S/ZnO$ also leads to reducing the particle size and consequently increasing the specific surface area. $Cd_{0.5}Zn_{0.5}S/ZnO$ materials with the larger $Cd_{0.5}Zn_{0.5}S$ content showed the higher activity in the photocatalytic degradation of rhodamine B under visible light irradiation. Therefore, the heterojunction effect between $Cd_{0.5}Zn_{0.5}S$ and ZnO as well as the adsorption capacity seems to give important contributions to the photocatalytic activity of the $Cd_{0.5}Zn_{0.5}S/ZnO$.
