Efficient preparation of nanocatalysts. Case study: green synthesis of supported Pt nanoparticles by using microemulsions and mangosteen peel extract

Abstract

The optimal approach to efficient nanocatalysts synthesis is to optimize both the yield and activity simultaneously. The optimization principle in this paper can also be more broadly applied to other multivariable processes.

Optimized Synthesis of FeNi/TiO2 Green Nanocatalyst for High-Quality Liquid Fuel Production via Mild Pyrolysis

“…The comprehensive data for optimizing the pyrolysis process using the central composite design method is presented in Table 3. We use the procedure published by Parapat et al [22] for the optimization. We note here that there were no replications for the variations.…”

“…This involves the utilization of mangosteen peel extract in the nanocatalyst synthesis at room temperature. It has been reported by Parapat et al [22] that mangosteen peel contains a phenolic compound, namely α-mangosteen, serving as the reducing agent in the mangosteen peel extract. This antioxidant plays a crucial role in the formation of nanoparticles.…”

“…Before synthesizing, we extracted the mangosteen peel using water as the solvent at 70°C for 30 minutes. With this mild extraction, the major bioactive substance (α-mangosteen) would be extracted [22]. Based on the reduction mechanisms of metal using antioxidants [41], the scheme of Fe 2+ and Ni 2+ reduction mechanism by αmangosteen is displayed in Figure 11.…”

“…Such flexibility in catalyst design enables the development of efficient and customized catalytic systems for the pyrolysis process. Researchers are still actively focusing on developing green and sustainable synthesis methods for catalyst preparation [21,22,23,24,25]. Utilizing natural and renewable resources as reducing agents can provide an eco-friendly alternative to conventional chemical reductants.…”

“…In this regard, mangosteen peel, a waste product generated by the food industry, has gained attention as a potential green and cost-effective source of reducing agents. Mangosteen peel is known to contain abundant bioactive compounds, including phenolics and antioxidants, which can serve as reducing agents and stabilizers during catalyst synthesis [22,23].…”
