| Abstract |
Two dimensional materials play a major role in state-of-the-art innovations for energy conversion because of potential applications resulting from their unique properties. These materials additionally show inordinate potential towards the progress of hygienic power sources to deal with increasing environmental disputes at a time of skyrocketing energy demands. Herein, we report earth-abundant, few-layered, BaNbFeO/gC3N4 nanocomposites, which reduce photogenerated electron and hole recombination by effectively separating charge carriers to achieve a high photocatalytic efficiency. Accordingly, the BaNbFeO/gC3N4 system produced effective hydrogen (1,600 µmol∙h−1) as of water using Na2S/Na2SO3 aqueous solution with the irradiation of solar-light. The presence of few-layered BNFO in gC3N44 successfully separates photogenerated charge carriers, thereby enhancing shuttling of electrons on the surface to active edge sites. To the best of our knowledge, this few-layered BaNbFeO/gC3N4 system exhibits the most effective concert among altogether reported gC3N4 based materials. Notably, these findings will ample prospective for the development of enormously real photocatalytic systems due to its economically viable and extraordinary efficiency. |
