Hydrothermal Synthesis - an overview

Hydrothermal Synthesis - an overview

Hydrothermal synthesis refers to material synthesis by chemical reaction performed within a sealed vessel filled with aqueous of reagents under temperatures above 100°C and autogenously high pressure. Different from the sol-gel and the coprecipitation methods (which will be described in S2.4), hydrothermal synthesis is usually carried out within specialized reaction vessels …

Hydrothermal Synthesis Autoclave Reactor (100 ML)

Hydrothermal Synthesis Autoclave Reactor (100 ML)

The reaction started by mixing a 0.375 g of Titanium Dioxide nanopowder (Degussa P25) with 50 mL of 10 M NaOH solution and stirring for 24 h. Then, sonication for 15 min was done to make sure no aggregation is left. Following this step, the mixture was heated in a sealed stainless-steel Teflon linear at 240 °C for 72 h.

The main synthesis involved the nitration of pyrene in HNO 3 at 80°C followed by the hydrothermal treatment in 0.2 M NaOH aqueous solutions at 200°C for 10 h. Post hydrothermal treatment the solution is dialyzed to get an overall yield of 63% black OH-GQD powder. The OH-GQDs in aqueous solution emit bright green fluorescence by UV irradiation.
