Performance of photocatalyst based carbon nanodots from waste frying oil in water purification

Abstract

Abstract. Carbon Nanodots (C-Dots) from waste frying oil could be used as a photocatalyst in water purification with solar light irradiation. Performance of C-Dots as a photocatalyst was tested in the process of water purification with a given synthetic sewage methylene blue. The tested was also conducted by comparing the performance C-Dots made from frying oil, waste fryng oil as a photocatalyst and solution of methylene blue without photocatalyst C-Dots. Performance of C-Dots from waste frying oil were estimated by the results of absorbance spectrum. The results of measurement absorbance spectrum from the process of water purification with photocatalyst C-Dots showed that the highest intensity at a wavelength 664 nm of methylene blue decreased. The test results showed that the performance of photocatalyst CDots from waste frying oil was better in water purification. This estimated that number of particles C-dots is more in waste frying oil because have experieced repeated the heating process so that the higher particles concentration make the photocatalyst process more effective. The observation of the performance C-Dots from waste frying oil as a photocatalyst in the water purification processes become important invention for solving the problems of waste and water purification.

Carbon Dots: Synthesis, Properties and Applications

“…Hence, aiming at a distinct perspective, we will compile a general review on the recent progress of the CDs. We intend to spotlight the latest advances in the CDs research, focus on synthesis, PL mechanism, and applications of CDs in this feature review [34][35][36][37][38]. Specifically, we first mainly summarize the synthesis routes to produce the CDs from different resources in especially low cost, and environmentally friendly natural biomass in Section 2.…”

Facile synthesis of luminescent carbon dots from mangosteen peel by pyrolysis method

“…C-Dots are new carbon nanomaterials with size below 10 nm, first obtain during purification of single wall carbon nanotubes (SWNCTs) through electrophoresis in 2004 [3]. Small size and strong photoluminescent properties of C-Dots have shown great impact in various applications such as optoelectronic devices, photocatalyst, electrocatalyst and bioimaging [1,[4][5][6][7][8][9][10]. Moreover, C-Dots can be synthesized from natural carbon sources in low temperature that shows green, cheap and facile synthesis process.…”

Plant Extract-Derived Carbon Dots as Cosmetic Ingredients

“…Pyrolysis carbonization is a basic approach for preparing C-dots. It has may advantages, including low toxicity, convenience, and simplicity [13]. The C-dot preparation can often be completed in one step without excessive equipment or complicated processes (Figure 1a) [13].…”

“…It has may advantages, including low toxicity, convenience, and simplicity [13]. The C-dot preparation can often be completed in one step without excessive equipment or complicated processes (Figure 1a) [13]. This method involves heating organic materials in the absence of oxygen to convert them into carbon-rich materials.…”
