Preparations and remarkable catalytic cracking performances of Pt@FGS/JP-10 nanofluids

Enhanced Fuel Decomposition in the Presence of Colloidal Functionalized Graphene Sheet-Supported Platinum Nanoparticles

“…35,36 Recently, Liu et al 33 developed Pt-coated graphene structures, which have been stably dispersed in JP-10. While Liu et al 33 demonstrated significant improvement in fuel conversion for JP-10 with 0.5 wt % additions of Pt-coated graphene structures, there is still limited information for either the efficacy or the mechanisms of enhancement of FGS-stabilized Pt nanocomposites at hightemperature and high-pressure conditions. Moreover, theoretical and numerical analysis, coupled with fundamental pyrolysis experiments, is also needed to understand potential interactions between the catalyst substrate and deposited catalytic metal with the fuel.…”

“…An alternative approach to functionalizing the nanoparticles explored here was to pin the nanoparticles to a high-surface-area substrate that serves to form the stable colloid with the hydrocarbon fuel and simultaneously prevent the sintering of the attached uncoated nanoparticles. The use of an FGS as a high-surface-area substrate can provide new directions in the development of multifunctional catalysts, allowing for low loading concentration and high activity. − ,,,− It has been shown that nanoparticles of platinum preferentially nucleate and are pinned at the lattice defects of FGSs, providing a very effective mechanism to arrest their growth through coalescence (i.e., no sintering). , Recently, Liu et al developed Pt-coated graphene structures, which have been stably dispersed in JP-10.

Synthesis of a High-Stability Nanosized Pt-Loaded MgAl2O4 Catalyst for n-Decane Cracking with Enhanced Activity and Durability

“…The chemical heat sink of the EHF cracking reaction can be enhanced efficiently by catalysts. − In recent years, catalytic cracking has been proven to be an effective way to improve chemical heat sink by changing the selectivity of the target products. Appropriate catalysts can increase the heat-absorption capacity by improving the selectivity of preferred products (like low-carbon alkenes) and conversion.…”

“…Appropriate catalysts can increase the heat-absorption capacity by improving the selectivity of preferred products (like low-carbon alkenes) and conversion. Based on related literatures, − two kinds of catalysts, including pseudo-homogeneous catalysts − and wall-coated catalysts, − are broadly studied for the EHF cracking reaction.…”
