| description | <p dir="ltr">The avenues of catalysis and material science are always accepted and it is hoped that a state-of-the-art catalyst with exceptional intrinsic redox characteristics would be produced. This study focused on developing a multi-featured catalyst of high economical and commercial standards to meet the multi-directional applications of environmental and energy demands. Manganese (IV) oxide nanosheets made of fluffy-sheet-like g-C<sub>3</sub>N<sub>4</sub> material were successfully synthesized by pyrolysis method. The electron-rich g-C<sub>3</sub>N<sub>4</sub> network and semiconducting metallic oxides of MnO<sub>2</sub> nanosheets generated high electron density interfaces within the intra-composite structure. The input of active interfaces along with strong metal-to-support interactions achieved between two parallel nanosheets in MnO<sub>2</sub>/g-C<sub>3</sub>N<sub>4</sub> catalyst intrinsically boosted up its electrochemical and optical characteristics for it to be used in multi-catalytic fields. Successful trails of catalysts’ performance have been made in three major catalytic fields with enhanced activities such as heterogeneous catalysis (reduction of nitrobenzene with rate constant of “K = 0.734 min<sup>−1</sup>” and hydrogenation of styrene with “100% conversion” efficiency, including negligible change in five consecutive cycles), photocatalysis (degradation of methylene blue dye model within 20 min with negligible change in five consecutive cycles) and electrocatalysis (oxygen reduction reactions having comparable “diffusion-limited-current density” behaviour with that of the commercial Pt/C catalyst). The enhanced performance of catalysts in transforming chemicals, degrading organic pollutant species and producing sustainable energy resources from air oxygen can mitigate the challenges faced in environmental and energy crises, respectively.</p><h2>Other Information</h2><p dir="ltr">Published in: Journal of Colloid and Interface Science<br>License: <a href="http://creativecommons.org/licenses/by/4.0/" target="_blank">http://creativecommons.org/licenses/by/4.0/</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1016/j.jcis.2021.12.023" target="_blank">https://dx.doi.org/10.1016/j.jcis.2021.12.023</a></p> |
