- Abstract
- 금 나노입자는 뛰어난 특성을 가지고 있기 때문에, 많은 연구에서 지지체로 많이 사용됩니다. 그 독특한 특성과 여러 표면 기능은 환경, 에너지, 촉매 분야에서 큰 주목을 받고 있습니다. 이러한 점에서, 금 나노입자를 기반으로한 복합체를 마찰전기 나노발전기(TENG)와 광촉매에 적용하였습니다. 금 나노입자를 TENG에 적용하면, TENG의 유전 특성을 향상시킬 수 있습니다. 금 나노입자를 포함한 다공성 PDMS 복합체는 TENG의 출력 성능을 증대시켰습니다. 광촉매로 사용한 경우에는, 금 나노입자와 반도체의 복합재료를 통해 광촉매 특성을 향상시켰습니다. 또한, 사슬과 같은 구조로 개질된 금 나노입자는 타이타늄과 결합하여 합성하였으며, 이 구조는 메틸렌 블루의 분해를 보여주었습니다.
Gold nanoparticle has good properties and often used as supporting material in many studies. Their unique properties and multiple surface functionalities have great attention in the field of environment, energy and catalytic. In this regard, we use Au nanoparticle-based composites for triboelectric nanogenerator (TENG) and photocatalytic applications. For the triboelectric nanogenerator application, Au NPs improves the dielectric properties of TENG’s active material. Au NPs-embedded porous PDMS composites have successfully enhanced the output performance of TENG. For the photocatalytic application, the combination of Au-semiconductor composites shows the enhancement of their photocatalytic activity. The modified chain-like Au NPs have been synthesized and combine with titanium. This structure has been demonstrated for the degradation of methylene blue
