Abstract

Treating diesel distillates containing polycyclic aromatic hydrocarbons (PAHs) not only reduces environmental pollution but also enhances the added value of diesel products, achieving resource recycling. In this study, an efficient and eco-friendly laser-induced method was employed to successfully synthesize a novel cathode hybrid material with a fluffy, porous structure (Zn_xMnO_x-rGO-C@LIG). By incorporating reduced graphene oxide (rGO) and diesel distillates into Zn_xMnO_x, the material’s electrical conductivity and surface area were significantly improved, thereby greatly boosting the performance of Zn-ion batteries (ZIBs). Furthermore, this work developed a Zn-ion hybrid supercapacitors (Zn-HSCs) device that combines ZIBs with supercapacitors, using an aqueous electrolyte to expand the voltage window. At a current density of 0.2 mA cm⁻², the Zn-HSCs achieved a specific capacitance of 806.3 mF cm⁻². As a novel energy storage device, Zn-HSCs exhibit advantages such as being non-toxic, with high power density and energy density.

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
