This novel material, composed of crystalline flakes, featured a broad absorption centered at 700¿nm, possibly due to charge transfer, and a 2.49¿eV band gap. Its catalytic performance was assessed for the treatment of effluents with the diazo dye Congo red, comparing it with that of boron carbon nitrogen oxide, BCNO. Both wide band gap semiconductors exhibited decolorizing activity in the dark, although the mechanisms were different and were not photocatalytic: BCNO was more effective towards the adsorption-coordination due to the presence of B-O, while C2N was effective towards the adsorption and the advancement of the oxidation reaction. Their kinetic constants (0.19 and 0.02 min-1 for BCNO and C2N, respectively) were comparable to those of intermetallic compounds studied for azo dyes degradation in dark conditions. In view of the high color removal efficiency (97% after 20¿min) and good reusability of BCNO, this study suggests a potential application of this catalyst for wastewater treatment, alone or in combination with C2N. 000084175 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000084175 590__ $$a3.408$$b2019 000084175 592__ $$a0.709$$b2019 000084175 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b115 / 314 = 0.366$$c2019$$dQ2$$eT2 000084175 593__ $$aMaterials Science (miscellaneous)$$c2019$$dQ2 000084175 593__ $$aCondensed Matter Physics$$c2019$$dQ2 000084175 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000084175 700__ $$0(orcid)0000-0003-2713-2786$$aMartín-Ramos, Pablo$$uUniversidad de Zaragoza 000084175 700__ $$aChamorro-Posada, Pedro 000084175 700__ $$aMeejoo-Smith, Siwaporn 000084175 700__ $$aVázquez-Cabo, José 000084175 700__ $$aRubiños-López, Óscar 000084175 700__ $$aLartundo-Rojas, Luis 000084175 700__ $$aSánchez-Árevalo, Francisco M. 000084175 700__ $$aTrakulmututa, Jirawat 000084175 700__ $$aRutto, Dario 000084175 700__ $$aDeebansok, Siraprapha 000084175 700__ $$aSrikhaow, Assadawoot 000084175 7102_ $$15011$$2500$$aUniversidad de Zaragoza$$bDpto.
