The synergistic effect between adsorption and photocatalysis with recoverable properties have attracted wide attention, and it is of great significance to construct a three-dimensional network structure catalyst with the properties of easy separation and recycle. In this study, three-dimensional network structure 3D-rGO/BP/ZnO was synthesized by a one-step hydrothermal method, which possessed adsorption enrichment with photocatalytic degradation of RhB. Black phosphorous (BP) and ZnO were uniformly distributed and anchored into 3D-rGO structure, which was characterized by SEM, XRD, SEM, Raman, FTIR and XPS. The 3D-rGO network structure promoted pollutant enrichment, providing a preferable platform for the interaction between RhB and 3D-rGO/BP/ZnO. Three-dimensional structures with different BP loads were selected to analyze adsorption and catalytic capacity. The adsorption experiments showed the pseudo-second-order kinetic model and Freundlich model were appropriate for describing adsorption behavior. The photocatalytic experiment revealed that 3D-rGO/7-BP/ZnO had the best photocatalytic performance, which degrade 93.0% of RhB in 120 min 3D-rGO/BP/ZnO heterostructure could boost the separation of photogenerated electrons and holes. Species capture experiments showed that superoxide radicals (·O 2 −) were the main active species. After three catalytic cycles, the photocatalysts exhibited excellent stability. This study offered a fresh perspective on the effective use of photocatalyst in environmental rehabilitation. [Display omitted] • BP and ZnO are successfully anchored into the 3D Graphene network structure. • The activity is ascribed to the synergistic effect of photocatalysis and adsorption. • The introduction of BP and rGO can boost the separation of electrons and holes. • The 3D-rGO/BP/ZnO composites composite shows a convenient recyclable operability.
