Abstract The synthesis of highly orderly hierarchical porous functional materials has always been a significant challenge in materials science. Herein, we employed natural materials to fabricate graphite carbonitride@wood-derived carbon (g-C3N4@WDC) with a micro-nano scale ordered interconnection porous structure using a simple two-step method and achieved the corresponding application dimensions. g-C3N4@WDC has the unique advantages of a wide pore size distribution, high ordered degree range, low manufacturing cost, and excellent mechanical strength. Furthermore, we have shown the heterotopic functional integration of the sample in photocatalysis and supercapacitors. As a result, excellent photocatalytic efficiency and high electrochemical capacity are obtained. These attributes meets the targets of green chemistry and sustainable development. This work is a demonstration of functionally integrated g-C3N4@WDC with an ordered interconnection porous structure and paves the way for using natural structures to prepare materials with high nanostructural-control and multifunctional integration for use in energy storage, adsorption, photocatalysis, environmental rehabilitation, oil–water separation, or other applications.
