Three-dimensional microspheric g-C₃N₄coupled byBroussonetia papyriferabiochar: facile sodium alginate immobilization and excellent photocatalytic Cr(iv) reduction

Abstract

g-C3N4–Broussonetia papyrifera biochar–sodium alginate composites were prepared. Composite recyclability and activity for photocatalytic Cr(vi) reduction and the origin of enhanced photocatalytic activity relative to that of g-C3N4 were probed.

Fabrication of a Nanosized g-C3N4-Loaded Cellulose Microfiber Bundle to Induce Highly Efficient Water Treatment via Photodegradation

“…He et al employed chitosan-derived carbon as a carrier to inhibit charge recombination and increase the surface area. Jin and his group immobilized g-C 3 N 4 onto sodium alginate to reduce electron–hole recombination and to achieve catalyst recovery. Although the use of the aforementioned carriers has improved the photocatalytic efficiency and recyclability of photocatalysts to some extent, it has not effectively solved the issues of aggregation and dispersion of g-C 3 N 4 .…”
