Abstract

This study explores the combination of SrTiO₃ (STO) with multiwalled carbon nanotubes (MWCNT) to evaluate its potential in water remediation and energy storage. A novel STO/MWCNT composite was developed through an environmentally friendly synthesis process with solvent free, enhancement of photocatalytic and supercapacitor properties. Under visible light irradiation, the STO/MWCNT degradation of methylene blue (MB), reaching 84.61 % efficiency within 120 min. To investigate the MB degradation mechanism, active-species trapping experiments revealed that hydroxyl radical ions play a dominant role in the process. Additionally, the optimized STO/MWCNT composite demonstrated excellent supercapacitor performance, with a specific capacitance (C_s) of 1189 F/g, significantly higher than bare STO (378 F/g) at a current density of 6 mA/g in 3 M KOH electrolyte. These findings highlight the remarkable photocatalytic and electrochemical capabilities of the STO/MWCNT composite.

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
