Sodium niobate (NaNbO<jats:sub>3<\/jats:sub>) has received much attention in the field of photocatalysis due to its excellent photocatalytic properties. However, the application of NaNbO<jats:sub>3<\/jats:sub> in the field of photocatalysis is still limited by poor reaction to visible light and easy recombination of photo-generated carriers. Heterojunction with g-C<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub> to construct core\u2013shell structure can effectively improve the above problems. Combining the two can design a core\u2013shell composite material that is beneficial for photocatalytic reduction of CO<jats:sub>2<\/jats:sub>. Herein, we prepared a core\u2013shell heterojunction g-C<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>\/NaNbO<jats:sub>3<\/jats:sub> by uniformly impregnating urea on the surface of NaNbO<jats:sub>3<\/jats:sub> chromium nanofibers with NaNbO<jats:sub>3<\/jats:sub> nanofibers prepared by electrospinning as a catalyst carrier, and urea as a precursor of g-C<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>. The core\u2013shell structure of g-C<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>\/NaNbO<jats:sub>3<\/jats:sub> was verified by a series of characterization methods such as XPS, XRD, and TEM. It was found that under the same conditions, the methanol yield of core\u2013shell g-C<jats:sub>3<\/jats:sub>N<jats:sub>4<\/jats:sub>\/NaNbO<jats:sub>3<\/jats:sub> was 12.86 <jats:italic>\u03bc<\/jats:italic>mol\u00b7g<jats:sup>\u22121<\/jats:sup>\u00b7h<jats:sup>\u22121<\/jats:sup>, which is twice that of pure NaNbO<jats:sub>3<\/jats:sub> (6.67 <jats:italic>\u03bc<\/jats:italic>mol\u00b7g<jats:sup>\u22121<\/jats:sup>\u00b7h<jats:sup>\u22121<\/jats:sup>).
