摘要

•Porous cPTA/CNT/CNU nanorod is prepared by using PTA as both template and adhesive.•A g-C3N4 isotype heterojunction forms on the cPTA nanorod surface in cPTA/CNT/CNU.•Optimal cPTA/CNT/CNU nanorod can degrade 95% RhB within 1 h under visible light.•A multistep electron transfer path from CNU, CNT to cPTA forms in cPTA/CNT/CNU.•Porous cPTA nanorod increases light harvesting, active sites and molecule channels.
