Rapid, High‐Temperature, In Situ Microwave Synthesis of Bulk Nanocatalysts

Abstract: Carbon‐black‐supported nanoparticles (CNPs) have attracted considerable attention for their intriguing catalytic properties and promising applications. The traditional liquid synthesis of CNPs commonly involves demanding operation conditions and complex pre‐ or post‐treatments, which are time consuming and energy inefficient. Herein, a rapid, scalable, and universal strategy is reported to synthesize highly dispersed metal nanoparticles embedded in a carbon matrix via microwave irradiation of carbon black with… Show more

“…Microwave heating is an effective way to induce thermal energy and has been used for the synthesis of organic and high-quality carbon materials, as well as carbon-loaded nanomaterials. We demonstrate in this work the use of microwave heating for the rapid and facile synthesis of HEA-NPs, as illustrated in Figure . The partially reduced graphene oxide film in argon at ∼570 K (named rGO-570 film) is employed as a model substrate.…”

“…Some noble and transition metal nanoparticles have also shown their capability in improving the OER performance [80] . For example, there have been published methods of loading Ru on modified graphene oxide or carbon black [81][82][83] . Batteries using these materials could be charged below 4 V. Some researchers have also devoted their attention to gel electrolytes.…”

“…Consequently, the metal NPs, including Ru, Pd, and Ir with a uniform size of~20 nm, were synthesized successfully, confirming the universal synthesis of NPs by MH. Moreover, Zhong et al [56] synthesized Ru, Pt, Pd, and Au NPs loaded on a carbon black matrix by MH. Taking Ru as a demonstration, a certain amount of commercial carbon black was first immersed in Ru 3+ solution, followed by freeze-drying to obtain a solid mixture.…”
