Carbon-dot confined in graphene-analogous boron nitride for enhanced oxidative desulfurization

As of late, graphene-like boron nitride (g-BN), has been created another schedule as aerobic catalysis, and have a profound effect on the key performance of the catalyst. In this paper, C-nanodots with low resistivity, were bounded through g-BN (C-dots/g-BN) to help electron versatility by a straight forward one-pot pathway. C-dots were bounded in graphene-analogous boron nitride (g-BN) via a one-step, in situ process at increased temperature, which could upgrade the interactions of C-dots and control the dimensions of C-dots in the scope of nearly 4-5 nm. The results demonstrated that C-dots/g-BN has a superior execution in high-impact oxidation of dibenzothiophene (DBT) in fuel oil with a reactant movement of 93.5%. Estimation showed that hydroxyl radicals produced from H2O2 as a result of the interaction with C-dots ended up a proficient catalyst in the framework. The C-dots had a synergetic impact to enhance the proficiency of H2O2 in the catalyst. The portrayal results showed that piece of the DBT was oxidized to its comparing sulfoxide which requires less oxidant than sulfone. Both of the oxidation items could be extracted in the oil phase on the catalyst. (C) 2022 The Authors. Published by Elsevier B.V. on behalf of King Saud University.

Automated summary

In this study, C-nanodots with low resistivity were combined with graphene-like boron nitride (g-BN) to form C-dots/g-BN catalyst. The catalyst showed superior performance in high-temperature oxidation reactions in fuel oil, with high catalytic activity and good controllability.
