Over the past decades, a new branch of plasma research, the nanomaterial (NM) synthesis by plasma-liquid interactions (PLIs), is rapidly rising, mainly due to the recently developed various plasma sources operated from low to atmospheric pressures. The PLIs provide novel plasma-liquid interfaces where many physical and chemical processes take place. By exploiting these physical and chemical processes, various NMs ranging from noble metal nanoparticles to graphene nanosheets can be easily synthesized. The currently rapid development and increasingly wide utilization of the PLI method naturally lead to an urgent requirement for presenting a general review. This paper reviews the current status of research on plasma-liquid 2 interactions for nanomaterial syntheses. Focus is on the comprehensive understanding of the synthesis process and perceptive opinions on the present issues and future challenges in this subject.

“…There have been many reports which focused on bubbles in relation to the generation of plasma in a liquid by a variety of methods [32][33][34][35]. The behavior of bubbles and plasma generated by high frequency waves and microwaves is observed using a high speed camera [36][37][38][39]. Microwave plasma is generated when the electrode is heated to the saturation temperature of n-dodecane [33,40].…”

Abstract:The in-liquid plasma method is a technology in which plasma of several thousand degrees Kelvin is generated within bubbles in a liquid. The purpose of this study is to enhance the hydrogen production rate from waste oils by using in-liquid plasma. Two types of microwave in-liquid plasma apparatus are adopted for hydrogen production. One is a conventional MW (microwave) oven, the other is a microwave generator with a waveguide to apply the in-liquid plasma steam reforming method in n-dodecane. The produced gas is 58%-90% hydrogen in these methods. The hydrogen production rate is improved by stabilization of the bubble growth. The gas production rate by plasma feeding steam in n-dodecane is 1.4 times higher than that without feeding steam.

The components of liquid radiography waste may be harmful or useful, depending on the composition of the raw material. This paper aims to remove the hazardous content from liquid radiography waste, while recoving the silver nanoparticles. The microwave plasma method was adopted to achieve this purpose. First, the conventional microwave oven was modified to generate the plasma in 100mL liquid radiogrpahy waste at 500W. The plasma generation time was varied for 1, 3, 4, 7, and 10min. In the treated liquid, the total suspended solid (TSS) was analyzed through vultraviolet spectrophotmetry, the silver (Ag) was examined through atomic absorption spectrophometory, and the biological oxygen demand (BOD) and chemical oxygen demand (COD) were discussed by titration method. In addition, the recovered silver was identified by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The resultsshow that the microwave plasma method reduced the TSS by 99.36%, the Ag by 92.73%, the pH by 3.42%, the BOD by 57.13%, and the COD by 57.14%; In addition, spherical shaped silver nanoparticles were indentified at some peaks with average crystallite size ranging from 2.64nm to 65.64nm. The research findings shed important new light on the recycling of liquid radiography waste.
