AB  - In this work, a protonated graphitic carbon nitride (P-g-C(3)N(4))-coated 
      graphene oxide (GO) composite (GO/P-g-C(3)N(4)) was prepared via wet-chemistry 
      exfoliation, followed by a freeze-drying process. The GO/P-g-C(3)N(4) composite 
      was found to have an outstanding photodegradation performance effect on the 
      reactive red 195 (RR195) dye and very strong antibacterial properties. Both the 
      GO structure and the dispersed state of P-g-C(3)N(4) were found to play a 
      significant role in enhancing the photocatalytic activity of GO/P-g-C(3)N(4). The 
      GO/P-g-C(3)N(4) obtained via freeze-drying retained a large number of 
      oxygen-containing groups and showed higher catalytic activity and reusability 
      than the reduced GO (rGO)/g-C(3)N(4) obtained via thermal reduction. 
      Characterization of the samples indicates that GO/P-g-C(3)N(4) has a higher 
      specific surface area and photocurrent density than rGO/g-C(3)N(4); it is likely 
      that these properties lead to the superior photocatalytic activity observed in 
      GO/P-g-C(3)N(4). Adsorption energy calculations indicate that O(2) can be readily 
      adsorbed onto the GO surface, which results in stronger oxidizing superoxide 
      anion radicals ((*)O(2)(-)) and holes (h(+)); these active radicals can rapidly 
      degrade RR195 dyes. Moreover, broad-spectrum antibacterial activity (demonstrated 
      against Staphylococcus aureus and Escherichia coli) was observed in the case of 
      the GO/P-g-C(3)N(4) composite irradiated with visible light. This work offers new 
      insights into the design of cost-effective g-C(3)N(4)-based photocatalysts for 
      environmental remediation.
